Saft to supply Li-ion batteries for RRS Sir David Attenborough polar vessel

Image Coming Soon - 1Saft will supply two Seanergy lithium-ion battery systems to Rolls-Royce Marine for integration in the hybrid propulsion system for polar research vessel RRS Sir David Attenborough.

The new vessel is being commissioned by the UK’s Natural Environment Research Council (NERC) for operation by the British Antarctic Survey. Rolls-Royce Marine has designed and will equip the RRS Sir David Attenborough. It is being built at Cammell Laird in Birkenhead, to which Saft will deliver the two battery systems in December 2017.

A Rolls-Royce diesel-electric propulsion system will be powered by new Bergen B33:45 engines that will operate in combination with two Saft patent-pending Li-ion Super-Phosphate high-power batteries.

Integrated into the vessel’s control and automation system, the batteries will provide a combined 1,450kWh capacity with a maximum voltage of 1,011V. They will help deliver the peak power required by the vessel, such as when operating in a dynamic positioning mode, and have been sized to enable the vessel to be self-sufficient in fuel during voyages of up to 19,000 nautical miles.

The Li-ion batteries will also help push the vessel through ice up to 1m thick, while towing equipment over the side. It will do so with extremely low underwater radiated noise, avoiding disturbing marine mammals and fish shoals or interference with survey equipment.

Helge Gjerde, offshore and merchant solutions president, Rolls-Royce Marine, said, “Our brief is to ensure that the RRS Sir David Attenborough is the very best-equipped ship of its type. There can be no compromise on any aspect of the vessel’s systems. That’s why we have selected Saft Li-ion battery technology as its proven safety, performance and reliability is the perfect complement to our hybrid propulsion systems.”

When the 128m-long ship enters service in 2019 it will carry out oceanographic and other scientific work in the Arctic and Antarctic, as well as transporting supplies to Antarctic research stations.

Finland’s oldest ferry converted to all-electric power

Image Coming Soon - 1Föri ferry, the oldest operating ferry in Finland, has become the nation’s first all-electric passenger vessel after being fitted with an electric propulsion system. The Föri initially entered service in 1904 after the city of Turku commissioned local shipyard Aktiebolaget Vulcan to build a city commuter ferry to take passengers across the Aura River to Åbo. It was officially relaunched last month.

Turku commissioned local boatyard Mobimar to complete the upgrade, and the vessel was dry-docked there in March this year. Mobimar oversaw the removal of the boat’s diesel-powered hydraulic motor and its old control system. The new installed system is 8 tonnes lighter, consisting of two Visedo Marine permanent magnet motor drives and two Visedo Marine DC/DC converters that control the ferry’s DC grid. The new vessel draws power from batteries that are charged overnight, with the new power system making it possible to run on one or two motors with uninterrupted operation.

Mobimar project manager, Antti Immonen, said, “For such a sensitive project we needed a partner who could deliver a new permanent magnet motor and charging technology built for purpose. There was no off-the-shelf solution. We were already impressed by Visedo during a previous collaboration to modernise a Korean Mark V65 submarine. There are now 240,000 passengers who have dived to depth below the Yellow Sea in a submarine with a Visedo-powered system. And we used some of the same components in the Föri.”

Toyota tests Japan’s first hybrid leisure boat in Tokyo

Image Coming Soon - 1Japanese car maker Toyota has developed Japan’s first leisure craft with a parallel hybrid system and will conduct a feasibility study from July 2018 to March 2021 in Tokyo.

In addition to its use for the maintenance of piers and other port facilities at the Port of Tokyo, PONAM-28V will be used for visits to Tokyo 2020 Olympic and Paralympic Games venues along the Tokyo Bay waterfront, as well as for canal tours at the Port of Tokyo.

PONAM-28V features a 3-litre internal combustion engine alongside a 36kW electric motor paired with an 11kWh lithium-ion battery pack. The internal combustion engine provides 256hp, and the electric motor provides 48hp and 347Nm of torque.

The Tokyo metropolitan government will provide the hybrid boat’s operational data to Toyota to help validate the overall performance of the hybrid system and to verify the convenience and improvement areas of hybrid boats.

ABB to power and remotely monitor new BW Group LNG FSRU vessel

Image Coming Soon - 1ABB will supply the power and electric propulsion system to BW Group’s new Floating Storage and Regasification Unit (FSRU), which will also be remotely connected to ABB’s Collaborative Operations Centers.

The equipment on board will provide data to the shore-side centres, allowing ABB and the vessel owner to take a proactive approach to maintenance throughout the lifetime of the vessel. “The modern power system must be both efficient and connected,” said Juha Koskela, managing director of ABB’s marine and ports business. “Our hardware will optimise fuel efficiency on board and the Collaborative Operations Centers will monitor the vessel, allowing a more informed approach to maintenance.”

ABB’s power generation and distribution system, along with the electric propulsion system, will work in conjunction with the duel-fuel diesel engine plant to maximise uptime. Much of ABB’s scope of supply of generators, switchboards, transformers, main propulsion drives and motors will transmit performance data via sensors. This information is automatically monitored from shore at the Collaborative Operations Centers, and ABB will work with the customer during routine and urgent maintenance cases.

The 174,000m3 capacity FSRU has been ordered from Daewoo Shipbuilding & Marine Engineering Co (DSME). The membrane-type vessel is expected to be delivered by DSME’s Okpo yard in 2019.

Siemens developing electric propulsion system for two new Norwegian ferries

Siemens has announced it is developing electric propulsion power and control technology, including batteries, for two new Norwegian passenger/car ferries operated by FosenNamsos Sjø AS.

The two vessels will work the 7.2km route between Flakk and Rørvik on Norway’s west coast, and each one will have loading capacity for 130 cars and space for 390 passengers. They are due to go into service in 2019.

Both ferries will use Siemens BlueDrive PlusC technology, which includes remote connection and monitoring support system EcoMain, a remote control system and energy management system, as well as an electric motor, switchgear and generators. The integrated control and automation system is for ferries and the shore-based charging stations, where the ferries and shore are to be monitored and controlled with a wi-fi solution.

BlueDrive PlusC’s power electronic technology will enable the ferries to operate on pure battery operation or together with diesel or gas engines at fixed or variable speeds, thus allowing motors to supply their maximum power at any load-dependent number of revolutions per minute.

According to Siemens, emissions, vibrations and noise will be eliminated while the vessels operate in pure electric mode. Furthermore, the electricity used will be climate-neutral because Norway generates its electric power from renewable energy sources, meaning no greenhouse gases will be created in the generation of electrical energy.

Rolls-Royce to provide automatic crossing system for FosenNamsos’ new hybrid ferries

Rolls-Royce has signed a deal with Norwegian shipbuilder Kleven to supply its automatic crossing system for two new double-ended plug-in battery-hybrid ferries being built for Norwegian ferry company FosenNamsos Sjø.

The system will control the ferries as they cross the fjord between Flakk and Rørvik connecting the peninsula of Fosen with Trondheim, ensuring safe and energy-efficient transit back and forth by automatically controlling the vessel’s acceleration, deceleration, speed and track. Two Rolls-Royce Azipull thrusters respond adaptively to environmental conditions to ensure optimal behaviour and maximise efficiency.

The captain supervises the automatic system and can intervene using conventional manoeuvring systems if needed. In the first deliveries the captain will manoeuvre the ferry manually until the last few metres to the dock. If the captain is unable to take manual control, the system stops the vessel and keeps it positioned until further action can be taken.

Jann Peter Strand, product manager, automation and control, Rolls-Royce Marine, said, “These additional orders for the automatic crossing system mean it is fast becoming the industry standard for double-ended ferry control systems, helping the customers meet their contractual need to ensure predictable energy consumption optimised for varying environmental conditions.”

Construction of the Multi Maritime-designed vessels will take place at the Kleven-owned Myklebust Verft Shipyard in Norway, starting in May. The vessels are due for delivery in late 2018 and will begin operation on 1 January 2019.

This order follows Rolls-Royce’s announcement of the sale of its first automatic crossing system to Norwegian ferry company Fjord1. Fjord1 will use the system to control two new double-ended battery ferries as they cross between Anda and Lote on the 1,330km-long E39, which connects communities along the west coast of Norway.

US passenger/vehicle diesel-powered ferry to be converted into all-electric vessel

Image Coming Soon - 1The Alabama Department of Transportation (ALDOT) has announced that the Gee’s Bend Ferry will be transformed from diesel-powered into a battery-electric vessel. The conversion is a joint federal-state project with a US$1m grant through the US Environmental Protection Agency.

According to state officials, it will become the first zero-emission passenger/vehicle ferry of its type in the USA. ALDOT estimates that each of the vessel’s four diesel engines runs up to 2,700 hours annually. As such, switching from diesel to electric power is expected to eliminate diesel fuel emissions and reduce the ferry’s operating expenses.

The ferry runs five round-trip voyages a day, 362 days a year, between the town of Camden and the rural community of Gee’s Bend in Wilcox County. An interim ferry will run until the power conversion is done in 2018. Funding for the conversion is part of the National Clean Diesel Funding Assistance Program.

“It is exciting that the state of Alabama will lead the nation with the use of this clean technology,” transportation spokesman Tony Harris said in a statement. “This is an opportunity for the Alabama Department of Transportation to showcase innovations, while maintaining this important passenger ferry service for the people of Wilcox County.”

A number of other organisations are involved in the project, including Seattle-based Glosten, which conducted the feasibility study; HMS Ferries, also based in the state of Washington, which operates the Gee’s Bend Ferry for ALDOT; Siemens’ marine division; and Alabama Power, which will enhance electric service to the Gee’s Bend Ferry terminal on the Camden side of the river.

Maersk Tankers, Norsepower, ETI and Shell collaborate to test wind propulsion technology

Image Coming Soon - 1Norsepower, in partnership with Maersk Tankers, Energy Technologies Institute (ETI) and Shell Shipping & Maritime, has announced it will install and trial Flettner rotor sails on board a Maersk Tankers-owned vessel.

The project will be the first installation of wind-powered energy technology on a product tanker vessel, and will provide insights into fuel savings and operational experience. The rotor sails will be fitted during the first half of 2018, before undergoing testing and data analysis at sea until the end of 2019.

Maersk Tankers will supply a 109,647-deadweight tonne Long Range 2 product tanker vessel that will be retrofitted with two 30m tall by 5m diameter Norsepower Rotor Sails. Combined, these are expected to reduce average fuel consumption on typical global shipping routes by 7-10%.

The project is majority funded by the UK’s ETI with contributions from Maersk Tankers and Norsepower. Shell will act as project coordinator, and provide operational and terminal/port consultancy to the project team, and Maersk Tankers will provide technical and operational insight.

Of the partnership, Andrew Scott, programme manager, HDV marine and offshore renewable energy, ETI, said, “Flettner rotors have the potential to reduce ship fuel consumption substantially, especially on tankers and dry bulk carriers. It is one of the few fuel-saving technologies that could offer double-digit percentage improvements. To date, there has been insufficient full-scale demonstration on a suitable ocean-going marine vessel to prove the technology benefits and operational impact.

“Demonstrating the technology in this project will make it more attractive to shipping companies and investors, and could play a significant role in reducing the fuel costs and improving the environmental impact of shipping in the future.”

Norwegian Maritime Authority to support development of hydrogen as marine fuel

Norway’s state-run Norwegian Maritime Authority (NMA) has expressed interest in using hydrogen as an alternative source of fuel for marine operations. The NMA also wants to partner with organizations within the industry to develop the new technology.

NMA senior surveyor, Kolbjørn Berge, said, “It is our opinion that the use of hydrogen as marine fuel is fully achievable, provided that the process is properly organized. The legislation does not hinder the development; on the contrary, it allows for new and innovative thinking when it comes to design and development of technology.

“The important thing is that the overall safety level is as high as for conventional oil-powered machinery, and there will be requirements for risk analysis and explosion analysis to ensure safe use.”

Norwegian Public Roads Administration is also currently preparing to challenge companies, shipyards and technology environments to build a hydrogen-powered ferry. The proposed project is expected to enable zero-emission technology for routes not suitable for electric operations.

In January the authority announced its involvement in the HYBRIDShips innovation project, which was initiated by Fiskerstrand Holding. The project seeks to develop the world’s first hydrogen-powered ferry, and will bring forward NMA’s approval process for the use of hydrogen as fuel in maritime transport.

NG3 releases Self Mooring and Release Technology system

Image Coming Soon - 1NG3, a startup company aiming to improve the energy efficiency and environmental footprint of the shipping and harbor industries, has released its Self Mooring and Release Technology (SMART) system.

Designed to automatically secure and release a mooring line to a vessel in seconds, the solution’s main technical feature is a self-locking hook, which, as a vessel approaches a quay, is automatically inserted into a ship-side receiving slot as a video tracking system automatically monitors the vessel’s position.

SMART has been specifically designed for short sea ferries, with a single SMART unit located mid ship; however, for larger vessels the required mooring capability can be met with several SMART units. According to NG3, this solution can maintain a vessel while quayside, even during short stops, thus avoiding use of the vessel’s main propulsion system and its subsequent emissions and fuel consumption outputs.

The system can be retrofitted on existing ships and terminals, and it allows for a reduction in power consumption and an increase in the time available to charge the battery from the shore.

ABS publishes Advisory on Hybrid Electric Power Systems

In an effort to provide “the critical information marine and offshore owners and operators need to make smarter decisions about energy generation and storage”, classification society ABS has published the ABS Advisory on Hybrid Electric Power Systems.

With an increased focus on compliance with environmental regulation and operational performance, ABS says many marine and offshore owners and operators are beginning to move their attention toward electric propulsion and alternative power sources.

As such, ABS explains that a measured approach was utilized in the development of the advisory, evaluating potential advantages and disadvantages, challenges and level of readiness for the primary hybrid-electric power systems and components that are best suited for marine and offshore applications.

The resulting list of technologies addressed in the advisory is noted to include lithium-ion batteries, supercapacitors, flywheel energy storage, fuel cells, wind and solar.

“In developing the advisory, we looked beyond the marine and offshore industries to determine how other sectors, like electric utilities and aerospace, have applied non-conventional power to products,” said Howard Fireman, ABS chief technology officer. “This advisory demonstrates our broad approach to analyzing information – identifying and evaluating how technology transfer can deliver comprehensive and practical tools for the marine and offshore industries.”

ABS says it worked with Sandia National Laboratories, among other project partners, to study the technical, economic and regulatory feasibility of building the SF-BREEZE, a zero-emission, hydrogen fuel cell-powered, high-speed passenger vessel, a concept for which ABS has issued a conditional Approval in Principle.

“Our work with Sandia Labs and the project team provided practical knowledge that was integrated directly into development of the ABS Advisory on Hybrid Electric Power Systems,” explains ABS.

World's first electrically powered boat for fish farming goes into operation in Norway

Image Coming Soon - 1The world's first battery-powered work boat for fish farming has been brought into operation in Norway. The Elfrida electric boat is used off the coast of Central Norway by Salmar Farming, a Norwegian salmon farmer.

Siemens developed and supplied the complete electrical propulsion and control system to the local shipbuilding company, Ørnli Slipp. The ship is equipped with Siemens’ BlueDrive PlusC propulsion system, which incorporates an energy management system, thruster and propeller controls, and EcoMain remote monitoring. The propulsion technology was developed in Trondheim, Norway, and is based on solutions designed for offshore ships.

The double-hulled boat, which is used to transport feed and equipment, to repair or relocate fish cages, check anchorages, and make inspections, is around 14m long and 8m wide. It requires around 50 minutes for its daily trip, sailing out of its home port of the Island of Frøya to the fish hatchery, which lies 12km off the coast. With BlueDrive PlusC, 100% battery operation is possible throughout a normal working day of about eight hours.

According to Siemens, Salmar Farming’s fishing fleet, which currently consumes 400 million liters of diesel each year, could reduce its fuel consumption by 80% by converting to electric propulsion, contributing toward the 40% reduction of CO2, to which the Norwegian government has committed itself.

All American Marine to build battery-electric hybrid ferry for Red and White fleet

Image Coming Soon - 1All American Marine (AAM) has signed a deal for the construction of a new battery-electric hybrid passenger vessel to be delivered to Red and White Fleet of San Francisco, California. The contract for the new 600-passenger aluminum monohull was signed at the Passenger Vessel Association’s annual Maritrends Conference, where it was also announced that Red and White Fleet will receive its new craft in late spring 2018.

The new vessel, to be named Enhydra, will be the first aluminum-hulled, lithium-ion battery-electric hybrid vessel built from the keel up under US Coast Guard subchapter-K passenger vessel regulations and the latest guidelines for structural fire protection.

AAM has partnered with BAE Systems to design and integrate the complete battery-electric hybrid system. BAE Systems will supply its HybriDrive propulsion system that includes a generator, control system, and AC electric traction motor. The generator will mount to a variable speed Cummins QSL9 410 diesel engine. According to AAM, the motor generator offers diesel-electric operation of the AC traction motor, which is coupled directly to the propulsion shaft. With this configuration, AAM says that torque is immediately available for the propeller and the speed can be precisely controlled without the need for a reduction gear.

The hybrid system will also use battery power from two 80kWh lithium-ion battery packs. The batteries will come from Corvus Energy and are supplied under its Orca Energy line. The BAE HybridDrive system can automatically use full electric battery operation at slower speeds and when maneuvering in and out of the harbor. At higher speeds, the generator will automatically engage and augment the additional power demands of the traction motor.

Red and White Fleet’s vice president of operations, Joe Burgard, said: “We see the propulsion configuration on the Enhydra as phase one in our move toward the full electrification of our fleet. Stay tuned for phase two.”

Rolls-Royce wins propulsion contract for US Coast Guard’s new Offshore Patrol Cutter

The hybrid solution was developed by Rolls Royce. In addition, Bellona, a non-profit organization working to meet and fight climate challenges, has been central to the project. Set to be launched in 2018, the MS Roald Amundsen’s inaugural season includes expedition voyages to Antarctica and the Chilean fjords.

Scandlines deploys two hybrid ferries on Rostock-Gedser route

Image Coming Soon - 1M/V Berlin and M/V Copenhagen, two new hybrid passenger and vehicle ferries operated by Scandlines, have entered service on the Rostock-Gedser route between Germany and Denmark, replacing two former Great Belt ferries that were no longer able to meet capacity requirements.

Both vessels, which were constructed at Danish shipyard Fayard, have been fitted with combined diesel mechanic and electric propulsion systems, including lithium-ion battery banks. According to Scandlines, this combination will enable the ferries to adjust their respective engine outputs and reduce fuel consumption by almost one-third per crossing per car compared to the route’s former ferries. And in the event that any of the diesel engines stops unintentionally, each vessel can rely on a redundant power supply.

Exhaust gas cleaners, called closed-loop scrubbers, have also been installed on both vessels. The scrubbers clean a minimum of 90% of the sulphur and particulate matter out of the exhaust gas, thereby emitting water vapour from the funnel of the ferry.

At 18,000kW, the vessels operate at speeds of up to 22kts (41km/h), and the 48.9km between Rostock and Gedser is covered in 1 hour and 45 minutes. With space for 460 cars, or 96 lorries, the capacity on the route has more than doubled. Furthermore, Scandlines has extended the timetable, with up to 21 daily departures.

Foreship appoints head of new technology for energy-saving agenda

Image Coming Soon - 1Naval architect and engineering company Foreship has appointed ship energy expert Jan-Erik Räsänen as its head of new technology with effect from March 1, 2017. Based in Helsinki, Räsänen will focus on helping owners implement energy-saving measures already developed by Foreship. He will also offer expertise on the application of digitalization, hybrid, battery and fuel cell technologies in shipping.

In a 20-year period with ABB, Räsänen played a leading role in advancing energy management and decision support through software and the adoption of battery technologies on working vessels, with landmark projects including the retrofit of the complete power and propulsion systems for two of the world´s largest emission-free electric ferries.

“This is a critical moment for shipping, given the range of technologies and many combinations available, and different views on whether battery technology is best installed at newbuild stage or during a retrofit,” said Räsänen. “Foreship’s involvement in design projects from the very beginning, where the potential for true innovation is at its greatest, offers the best platform for my experience. I am convinced that one of the main cruise ship players will make a commitment to battery power before the end of this year, and Foreship’s goal is to consider the complete picture and design the best-performing ship. Technical objectivity is best achieved at this early stage, before suppliers become involved.

“Cruise owners are aware that battery technology has been proving itself in the ferry market, especially in the commuter sector,” added Räsänen. “The basic technologies we have in our hands today will be around for the coming 5-10 years. However, costs are likely to fall over the next two years, while I expect different battery chemistries to serve energy and power applications. This is a decisive moment for alternative energy sources in shipping.”

Color Line signs LOI on world’s largest hybrid vessel

Image Coming Soon - 1Norwegian cruise and transport shipping company Color Line and shipbuilder Ulstein Verft have agreed on a Letter of Intent (LOI) for the construction of the world’s largest plug-in hybrid vessel.

To be designed by Fosen, the vessel, currently dubbed Color Hybrid, will be 160m long and have a capacity of 2,000 passengers and about 500 cars. It is planned to service the Sandefjord-Strömstad route from summer 2019.

The ship will use battery power into and out of the fjord to Sandefjord, meaning it will not emit any greenhouse gases or nitrogen and sulfur compounds in this area.

“The signing of the LOI represents a significant step to realizing the world’s largest plug-in hybrid ship,” said Trond Kleivdal, group president, Color Line. “It is very gratifying that the Norwegian shipbuilding industry has proved its competitiveness internationally.”

With shore power facilities already at ports in Oslo, Larvik and Kristiansand, the installation at Sandefjord means that all Color Line Norwegian ports will have shore power facilities.

Asia’s first hybrid ferry heralds cleaner sea travel

Image Coming Soon - 1The Taiwanese harbor city of Kaohsiung has launched a new hybrid ferry, which aims to curb greenhouse and diesel emissions for marine passenger transport across the region.

Kaohsiung recently relaunched the Cijin Island passenger ferry, retrofitted with a Visedo Marine electric propulsion system to replace the original diesel engine. It heralds Asia’s first hybrid-electric ferry and, if successful, the Kaohsiung city government plans to retrofit the rest of its diesel fleet to help reduce pollution levels around Taiwan’s largest harbor.

Visedo, a Finnish manufacturer of electric drivetrains for marine vessels, worked alongside Taiwan’s Ship and Ocean Industries R&D Center, also known as SOIC, to complete the retrofit.

Kaohsiung’s new e-ferry, Ferry Happiness, will halve daily fuel consumption while transporting 15,000 passengers every day to Cijin Island, a popular tourist destination in Taiwan, at a top speed of nine knots.

Launching from berth every 15 minutes, the ferry will help share the eight million passengers who travel the 650m route every year. It’s estimated the electric propulsion will save more than 25,000 liters of fuel every year.

Visedo retrofitted the 100-ton, 23m-long vessel with an electric system to replace the original 300hp diesel engine. The powertrain was designed to ensure pure-electric cruising for half the ferry’s operation time; with fast shore charging, this pure-electric percentage can be higher.

Visedo CEO Kimmo Rauma said, “Given the geography, ferries are a vital mode of public transport across East and Southeast Asia but they are also the most energy intensive per kilometer traveled. Until now, diesel ferries have been a dirty but necessary part of life around harbors like Kaohsiung.

“Visedo has developed a cost-effective and efficient alternative, so rather than waiting until a vessel’s service life ends, harbor cities can swap noisy, dirty and expensive diesel for silent electric powertrains that are more efficient, can halve fuel costs and emit no fumes or oil pollution.”

ABB progresses with electrification of world’s largest electric ferries

Image Coming Soon - 1A project to convert two HH Ferries vessels into the world’s largest emission-free ferries is progressing after ABB revealed that Öresund DryDocks has been selected to carry out the work.

Representing a US$32.7m investment – US$13m of which is being co-financed by INEA, the EU’s executive agency for innovation and network – M/F Tycho Brahe and M/F Aurora will both be fitted with 4.16MW of batteries and the containers with the battery racks will be lifted on board in February 2017. The dry-docking of Tycho Brahe will begin in April and will start operating as a fully electric ferry immediately upon completion. Aurora will undergo the same process in October 2017.

This project also includes the installation of four fully automated shore-side charging arms, which are currently under construction in ABB’s factories. Civil work will be completed at the quayside in Helsingör and Helsingborg in the beginning of next year.

Henrik Rørbæk, CEO of HH Ferries, said, “Our conversion of the Tycho Brahe and Aurora ferries to battery operation is an essential part of our environmental strategy to reduce emissions and reduce the environmental footprint of our operations on Öresund. We are proud of the initiative, which is the largest single project investment in the company’s history.”

ABB’s delivery for modernizing the ferries includes batteries, an energy-storage control system and Onboard DC Grid technology. At both ends of the route ABB will supply the first automated shore-side charging stations using an ABB industrial robot, to optimize the connection time and therefore maximize the charging period.

The two ferries will operate completely on battery power between Helsingør (Denmark) and Helsingborg (Sweden), a distance of approximately 4km carrying more than 7.4 million passengers and 1.9 million vehicles annually. According to ABB, the new battery solution will help lower total emissions across the fleet by more than 50% from the current diesel operated vessels. The combined battery power of 8,320kWh for the two ferries is the equivalent of 10,700 car batteries.

Derecktor to build second Hybrid Series vessel

Image Coming Soon - 1Derecktor Shipyards has announced that its next project will provide an alternative transportation platform for organic food shipping just off the northeast coast of the USA.

Powered by a BAE HybriDrive propulsion system utilizing Cummins QSB6.7 diesel engines, the Organic Market Delivery vessel is based on a 19m aluminum catamaran platform designed for efficient operation in coastal waters. Configured to carry 9,000 lb of protected refrigerated cargo and 3,000 lb of deck cargo, the vessel can travel emission-free for three hours before its lithium battery needs to be recharged.

Along with Harbor Harvest, Derecktor is creating an eco-friendly marine coastal network that will integrate a retail space along with the support of an organic farm market in the Connecticut/Long Island Gold Coast and Long Island Sound area. The US ship constructor says the trade routes have already been tested to confirm the fuel efficiency and battery life, and the vessel will be able to be charged at shore-side facilities along its route.

Scandlines’ new hybrid ferry uses Corvus Energy ESS

Scandlines’ latest hybrid ferry, M/V Copenhagen, will utilize a low-emission and fuel-saving diesel electric hybrid propulsion system powered by a Corvus Energy ESS (Energy Storage System). M/V Copenhagen is the sixth Scandlines hybrid ferry to use a Corvus ESS.

The new hybrid ferry will soon join its sister ship, M/V Berlin, which is also powered by a Corvus ESS, in servicing the crossing between Rostock, Germany, and Gedser, Denmark. M/V Copenhagen is 169.5m long and 25.4m wide, providing capacity for 460 cars or 96 transport trucks, and 1,300 passengers. The main engines provide an output of 18,000kW, with a further 4,500kW available from the Corvus ESS, resulting in a speed of 21kts on the 105-minute-long crossing.

M/V Copenhagen uses an optimized propulsion system consisting of propellers and two thrusters, which can be rotated through 360° and are used in narrow waterways or during maneuvers in port. On the emissions front, the vessel has four scrubbers that remove harmful substances from the exhaust gases such as sulfur oxides and fine particles.

Energy-saving solutions are used wherever possible to reduce the amount of energy required to run the vessel, including LED lighting throughout and the use of variable-frequency controls to optimize energy usage. When consumption is lower, excess energy is stored in the Corvus ESS. This energy is then released when consumption is higher than generator production.

Norwegian Electric Systems wins TFL hybrid ferry contract

Image Coming Soon - 1Norwegian Electric Systems (NES) has signed a US$3.5m contract with Remontowa Shipbuilding, in Gdansk, Poland, for the delivery of two LMG Design hybrid propulsion systems for two new ferries operated by Transport for London.

The ferries will operate along the route between Woolwich and North Woolwich on the River Thames, in London, UK. The current Woolwich ferry has been in operation since 1889 and carries around 20,000 vehicles and 2.6 million passengers per year across the River Thames.

NES’s package consists of converters forming a DC-grid system with four battery systems, two of each located on each side of the DC-bus for redundancy. In addition, water-cooled permanent magnet motors and four direct-driven propellers are used for the main propulsion.

“We have had good and close contact with Remontowa and LMG Design during this sales process,” said Fridtjof Erichsen, regional sales manager, NES. “We are proud to have won this contract. It proves once again that NES is at the forefront of hybrid propulsion technology.”

WE Tech and Switch to provide generator solution for Toll Shipping’s two new vessels

WE Tech Solutions and technology specialist Switch have been selected to provide their permanent magnet shaft generator solution to Toll Shipping, Australia’s two new roll-on/roll-off (ro-ro) vessels.

Delivery of the equipment, which includes WE Tech’s variable-frequency drive technology and Switch’s PM shaft generator solution, is scheduled to begin by August next year. The solution, to be equipped in the two 12,000 deadweight tonnage ro-ro vessels, will help the main engine of the ship to operate at variable speeds.

Additionally, both the online direct-drive shaft generators will generate power of up to 3,400kW for the ship’s electrical network. Once completed, the new vessels, to be built at Jinling Shipyard in China, will replace Toll’s existing ro-ro vessels.

WE Tech Solutions’ sales manager, Martin Andtfolk, said, “Thanks to WE Drive, the propulsion machinery can be operated at optimal duty points at all vessel speeds. This saves an enormous amount of fuel and substantially decreases environmentally harmful emissions. The solution also efficiently distributes power to the bow thrusters.”

The company also noted that its solution would help save fuel when the vessels are in the harbor. The equipment further delivers up to 3,000kW of cleaner and cheaper shore power for the vessels’ electrical network, reducing the need for using auxiliary generators.

Currently, Toll Shipping provides shipping services between Tasmania and mainland Australia.

Toshiba integrates fuel cell system into experimental hybrid vessel

Toshiba Corporation Energy System and Solutions Company (ESS) has integrated a hydrogen fuel cell system into an experimental vessel called Raicho N. The 14m-long boat has a cruising speed of 8kts and was developed as part of a joint research project by NREG Toshiba Building, a group company of Nomura Real Estate Group, and the Tokyo University of Marine Science and Technology.

“We installed two stationary pure hydrogen fuel cells on the boat, both with an output of 3.5kW,” said Hiroyuki Ota, general manager of ESS’s New Energy Solution Projects Team. “We now have the boat that runs on clean energy sources with zero-carbon emission, which produces high power output in a short period of time.

Raicho N started its proving tests in October 2016. NREG Toshiba Building and Tokyo University of Marine Science and Technology are to identify issues of seaborne use of pure hydrogen fuel cell systems, aiming to commercialize the hydrogen-powered vessel by 2020.

The results will also be reflected in safety guidelines for fuel cell boats, which are to be developed by Japan’s Ministry of Land, Infrastructure, Transport and Tourism.

Li-ion battery tech discussion

Following reader response to the cover story in the latest issue of Electric & Hybrid Marine Technology International (click here to read now), we asked experts across the maritime sector whether lithium-ion should be pursued for battery systems powering electric and hybrid marine applications. Here’s what they had to say...

Stephen Tartaglia, engineering manager, Lithionics Battery

Lithium-ion chemistries fall into two categories: organic (iron phosphate) and inorganic (NMC, NCM, NCA called nickelates or cobalt-bearing chemistries). Iron phosphate exists in nature and all other lithium chemistries are synthesised covalent bonds. The failure mode leading to thermal runaway events is the breakdown of the covalent oxygen bonds. We’re in favour of using iron phosphate. Additionally, we’re against using all other chemistries in the marine environment. Now, not all iron phosphate cells are created equal; there are still good and bad. But the sad truth is that the world community is not being properly informed of the differences between lithium-ion chemistries. Some well-funded companies push the lower-cost, environmentally hazardous and less-safe inorganic chemistries. Iron phosphate does not fall into the same camp. It is more expensive, RoHS compliant and green, and, inherently (naturally) safer.

Graeme Hawksley, founder and managing director, Hybrid Marine

We’ve been following lithium-ion battery technology development for quite some time, and although it’s capable of being safe in a marine environment, I don’t think we’ve reached the point where we fully understand what it takes to be so. As a system integrator it’s very difficult to make safety decisions based on battery manufacturers’ claims. Every supplier says its lithium-ion technology is entirely safe, but we have no way of making judgments here. The performance offered has many advantages over lead-acid when considering hybrid systems, but we have not embraced this technology due to the high cost and safety concerns.

Tania Berry, senior technology specialist, electrotechnical systems, Lloyd’s Register

Lithium-ion should be pursued but the approvals process needs reappraisal. Lloyd’s Register takes an integrated approach. As a classification society we’re involved from the concept design phase in order to ensure the safety of the battery installation, not only as part of the vessel’s electrical system but as part of the whole ship as a system. This identifies potential safety issues from the outset. But with the extensive range of cell chemistries, it isn’t considered appropriate to use prescriptive rules. We’re moving on from the usual type approval process to allow manufacturers to adopt new cell chemistries as technology evolves. As such, we’ll carry out an Approval in Principle for proposed battery management systems and adopt a risk-based approach to accepting specific designs.

Greg Atkinson, director and chief technology officer, Eco Marine Power

Though lithium-ion has a higher energy density compared with lead-acid, newer lead-acid batteries can now match the cycle life of lithium-ion batteries and cost considerably less. If there’s limited space on a vessel or if weight is a critical issue, then perhaps lithium-ion is the best solution. However, lithium-ion batteries generally require a more complicated charging circuit than lead-acid batteries, plus protective circuitry to prevent thermal runaway. Some lithium-ion battery packs also require a dedicated cooling system, substantial mounting frame or battery case and, if retrofitted to a ship, the fire protection system may need to be upgraded. It may also be complicated (or not possible) to transport lithium-ion batteries by air, whereas lead-acid batteries can be loaded as cargo onto aircraft. This makes it easier to support projects globally and supply spares quickly if needed.

Tim Tiek, CEO, Super B

In recent years the demand for energy storage has grown quickly. Several battery solutions have been used and we see the market trending towards lithium-ion because of its high charge/discharge performance, long maintenance-free lifetime and low weight. However, many different lithium-ion chemistries and battery designs exist, with big differences in safety, reliability, lifetime, efficiency and overall performance. For marine applications, Super B favours modular lithium iron phosphate-based batteries with integrated BMS. This design ensures maximum safety and meets demanding lifetime requirements. This has been our philosophy for many years and we’re glad to see this confirmed by industry experts, customers and formal type approval companies.

Pieter Dijkstra, managing director, Visedo Marine

Supplier selection is crucial in battery safety and should be focused on much more by the marine market. It’d be best if all battery suppliers followed the same general testing rules. If they don’t, then they shouldn’t be allowed to enter the market. A four-level safety system testing guideline should be adhered to, starting at cell safety through to module safety, battery system safety and up to total drivetrain safety. Then, only the best and safest cells and chemistries will provide the base for a complete system. Unfortunately, some battery systems today are built with used cells, and their lack of safety is covered up by the battery’s module structure, cooling system and BMS. However, covering up flaws of a cell design through production techniques and choice of chemistry doesn’t solve the underlying problems of the cells themselves. Some suppliers approach the market with a ‘you only live once’ attitude and try to convince you to take a gamble. This puts huge pressure on system design and price, and flushes safety down the drain.

Andreas Kristoffersen, head of section, electrical systems, DNV GL Maritime

For maritime applications the challenge with lithium-ion comes in terms of managing the risks related to a thermal runaway, possible gas development and fire/explosion hazards. The challenge can be met by ensuring a safe design of the battery system itself, and by taking necessary safety precautions in the space in which the batteries are installed. The former can be verified through a general type approval of the battery system, which is a comprehensive assessment and testing of the battery design and control system; the latter has to be evaluated case by case based on the chosen battery system and vessel design. Alternative chemistries such as lithium-air and lithium-sulphur, which have superior energy density, or magnesium-ion or aluminium-ion, which could be more cost competitive, or even graphene, which could bend both cost and efficiency curves, may find their way into the maritime and offshore industry in the future. But as of today, they are not production-ready technologies and also face the challenge of scaling up production to industrial volumes.

Fini Hansen, technical superintendent of fleet management, Scandlines

We’ll be pursing lithium-ion battery technology – we’re confident in it. Our top priorities are safety, reliability and long lifetime. Marine applications are totally different to phones and electronics – there is much more safety prevention in marine installations. As such, we can be supplied with a marine type-approved lithium polymer NMC technology battery module that’s well suited to powering a powerful and lightweight diesel-electric vessel. We’ve sourced one that is highly rugged, comes sealed in an aluminium casing and can withstand 50 gravities of impact and 8g five-axis continuous vibration.

Tatsuya Ohno, research and development, naval machinery, Kawasaki Heavy Industries

We’ll pursue it. There are many kinds of lithium-ion battery in the world – all with quite different characteristics. Although some lithium-ion batteries pursue high power or high energy, for ship propulsion the most important thing is safety. So, if you select the cell properly, checking against strict and appropriate test requirements, I think there’s less risk of firing in the way the Samsung batteries have. A ship should allow for a much more rigorously controlled environment. The classification requirements are prudent: you need to design the battery room with cooling, firefighting and ventilation systems.

E-ferry automation and control technology supplier revealed

Image Coming Soon - 1Valmet will supply automation and remote control technology for electric ferry concept, E-ferry, in the second quarter of 2017.

Compared with a similar-sized diesel-powered ferry, the fully electric-powered vessel is expected to deliver annual CO2 emissions savings of about 2,000 tons and NOx emissions savings of 41.5 tons. Furthermore, with a 4.2MWh battery system, the vessel is reported to offer the highest capacity of any electric ferry to date.

The order for Valmet’s automation and remote control technology was made by Visedo Marine, which is supplying the E-ferry’s electric propulsion system. “Valmet’s solution is technically excellent, and the company was able to present strong references,” said Hanna Huppunen, director of service at Visedo Marine. “The technology is a good complement to Visedo’s drivetrain system in the E-ferry.”

E-ferry, which has received funding from the European Union’s Horizon 2020 research and innovation programme, is slated to operate in the Baltic Sea, running between the island of Aeroe and the Danish mainland.

New electric rudder drive unveiled by Hanse Yachts

Image Coming Soon - 1Hanse Yachts has introduced the 315 e-motion rudder drive, offering improved manoeuvrability as well as emission-free and near-silent propulsion in recreational applications.

The new drive, which was developed in cooperation with Jefa and Torqeedo, has a 4kW electric motor that not only replaces the diesel engine and its components, but also the complete sail drive.

Along with the engine, a folding propeller has been integrated into the rudder shaft. The engine directs the thrust in the respective direction of the rudder. According to Hanse, the extended rudder angle of 100° allows the 315 e-motion rudder drive to turn from standstill on its own axis, forwards and backwards.

The system consists of two to four lithium-ion batteries, which propel the yacht at 4.5kts as far as 30 nautical miles. At lower speeds, the range is extended significantly; the maximum speed is 6.1kts.

Scandlines names new hybrid ferry

Image Coming Soon - 1The second of Scandlines’ two new hybrid ferries for the Rostock-Gedser route has been named Copenhagen. Together with sister vessel Berlin, the new hybrid ferry will connect the capital cities of Germany and Denmark.

“It has been interesting, challenging and sometimes frustrating to be part of this project,” said Scandlines chief executive Søren Poulsgaard Jensen. “On the other hand, we have all had to do our best to succeed. I am immensely proud to be able to welcome everyone on board our new ferry, even though I know there is still some finishing to be done so it will take a few weeks before the ferry goes into service.”

Copenhagen is currently undergoing testing and, in late November, it will start its sea trials, where manoeuvrability will be tested under usual and unusual conditions. Scandlines expects Copenhagen to go into operation before the end of the year.

Cavotec secures major MoorMaster equipment and servicing orders

Image Coming Soon - 1Marine systems supplier Cavotec has won major MoorMaster automated mooring orders worth US$10.7m from existing MoorMaster customer, the Port of Salalah in Oman, for use at two container berths.

The company is to supply 16 MoorMaster MM400E15 units for container Berths 3 and 4 at Salalah. A three-year maintenance contract has also been signed – a renewal of an existing agreement – which will see Cavotec on-site service teams working with the port to provide support at all five MoorMaster berths.

“We’re delighted to continue our work with Cavotec, helping to improve safety and optimise operations with MoorMaster,” said Joe Schofield, Port of Salalah COO. MoorMaster units were first trialled at Salalah in 2006, and the technology was then introduced at Berths 1 and 5. The technology has successfully reduced excessive vessel motion, common to the port, caused in part by long waves that occur during the Khareef monsoon season.

The new units – eight each at Berths 3 and 4 – are scheduled for installation before the 2017 Khareef season. Earlier this year, and prior to the 2016 Khareef season, eight MM400E15 units were installed at Berth 6.

Corvus Energy’s Orca ESS selected to power hybrid cargo transport vessel

Image Coming Soon - 1Halvorsen Power System has selected Corvus Energy as the supplier of the lithium-based energy storage system (ESS) for a retrofit of a hybrid cargo transport vessel called MS Hannah Kristina. Corvus will supply its Orca Energy solution to provide all required energy to the vessel during harbour operations, resulting in zero emissions.

The hybrid cargo transport vessel will utilise a 1,000kWh Orca Energy ESS to provide 100% of the vessel’s energy requirements during harbour operations. This not only reduces fuel and operating costs but also drastically reduces the environmental impact of the vessel.

“The Orca Energy ESS from Corvus was an extremely compelling solution for this application,” said Hans Petter Heggebø, CEO at Halvorsen Power Systems. “By combining industry-leading safety, performance and economic feasibility, Corvus has achieved the ultimate maritime ESS with Orca. We really enjoy working closely with the skilled and enthusiastic Covus team in Bergen.”

World’s first expedition ships with hybrid propulsion

Image Coming Soon - 1Norwegian coastal exploration travel company, Hurtigruten, will invest in a hybrid propulsion solution for two new 530-passenger expeditionary ships in a bid to reduce fuel consumption in the Arctic and Antarctic.

According to Hurtigruten, the 20,000-ton ships, constructed at Kleven Yards in Norway, will be the world’s first expeditionary ships with hybrid propulsion; at US$15m, they represent the largest singular investments in the 123-year history of the company. Enova, a Norwegian government enterprise that promotes eco-friendly energy production and consumption, is contributing US$5.5m to the project.

The hybrid ships will be built in two phases. The first ship, which will be delivered in July 2018, will be equipped with an auxiliary electric engine that will reduce CO2 emissions by 20%, or 6,400 tons per year compared with conventional ships. Meanwhile, the second vessel, which will be delivered in July 2019, will feature a hybrid engine that can power the entire ship for longer periods of time and distances, into fjords and in vulnerable areas. The technology, which has been developed by Rolls-Royce and Bellona, a non-profit organization that works to address climate change, will allow for sailing for up to 30 minutes on battery-powered propulsion.

“The future of shipping is, without a doubt, silent and emission free,” said Daniel Skjeldam, CEO of Hurtigruten. “We will use our new expeditionary ships as groundbreakers for this new technology, and show the world that hybrid propulsion on large ships is possible today.”

Color Line to build world’s largest hybrid ferry

Image Coming Soon - 1Norwegian ferry operator Color Line says it will build the world’s largest hybrid ferry and put it into operation on the route between Sandefjord and Strømstad from 2020.

Set to feature a plug-in hybrid propulsion system, the vessel’s batteries can be recharged via a shore-to-ship power cable or via its onboard generators. The ferry will be able to enter and exit the fjord to Sandefjord on full battery power.

Currently called Color Hybrid, the ferry will be 160m long and have a capacity of 2,000 passengers and 430-500 cars.

The Switch acquires Wärtsilä’s marine drives business

The Switch, a technology specialist of advanced drivetrains, has acquired Wärtsilä’s marine drives business, encompassing specialized megawatt-class power drives for marine applications.

As part of the Yaskawa-backed deal, The Switch will gain part of Wärtsilä’s Electrical & Automation (E&A) test center and manufacturing facilities in Stord, Norway. The Switch will then become a supply chain partner of Wärtsilä for marine drives while also being able to open up the product offering to other customers. The business transition from Wärtsilä to The Switch is due for completion once operations have been transferred to The Switch.

“The Wärtsilä drive products are specially made without compromise for marine applications,” said Jukka-Pekka Mäkinen, president and CEO of The Switch. “These products are ready for integration with various other systems because of their superior communication features, including de facto industry-standard interfaces and remote management possibilities. It is also possible to separate the logistics for cabinets and power modules by shipping them later to avoid damage during the long installation times at shipyards.”

Image Coming Soon - 1Wärtsilä has selected Corvus Energy as the supplier of the lithium-ion-based energy storage system (ESS) for a new hybrid ferry being built for UK-based Wightlink Ferries. The company will supply its next-generation Orca Energy ESS solution.

The new ferry, entering into service in 2018, will serve the crossing between the Isle of Wight and the English mainland 20 times per day, carrying up to 178 vehicles and more than 1,000 passengers.

“This new environmentally friendly ferry represents our third major vessel project with Wärtsilä, and we are pleased that the industry-leading innovation in safety, reliability and performance of Orca ESS is being recognized,” said Halvard Hauso, executive VP, sales and marketing, of Corvus Energy.

Xalt Energy to supply battery cells for world’s largest electric ferries

Xalt Energy, with Plan B Energy Storage (PBES), has announced the cell supply contract for the two largest battery-powered ferries in the world.

Each of the two Scandlines Helsingborg-Helsingör ferries will have 4.16MWh batteries to provide power for primary propulsion. The electric ferries will carry more than 7.4 million passengers and 1.9 million vehicles annually with zero emissions.

The energy storage system was designed by PBES, with a proprietary liquid cooling system. The thermal management system maintains optimal internal temperatures to maximize the lifespan of the Xalt high-power lithium cells.

“The Xalt quality processes are the best in the world,” said Grant Brown, vice president of marketing for PBES. “The resulting products are capable of higher discharge rates, better performance, and ultimately far greater cycle life than their competitors. By maintaining optimal core temperatures for the cells, PBES modules maximize the lifespan of the cells.”

The Innovation and Networks Executive Agency, the European Union’s executive body for innovation and networks, is supporting the project with an investment of US$14.1m.

Saft wins lithium-ion battery contract for Zoza luxury mega-yacht

Image Coming Soon - 1Saft has won a lithium-ion battery system contract from the future owner of the Zoza luxury mega-yacht, representing the company’s first such contract in the luxury yacht market.

Project Zoza is the working name for the mega-yacht under construction by Benetti in Livorno, Italy. It will reportedly be one of the largest and most advanced private hybrid luxury yachts in the world, featuring a propulsion system with six main engines and an electrical powerplant featuring two battery systems with a total capacity of 3MWh.

The batteries will enable silent propulsion, as well as peak shaving and zero-emission operation in harbor. The two batteries will deliver power at 600V using Saft’s high-energy air-cooled lithium-ion Super-Iron Phosphate (SLFP) electrochemistry.

Saft is also creating a customized mechanical structure to integrate into the hull and alongside other equipment. It will supply the battery systems as well as battery management, control, safety and communication systems.

Vincenzo Poerio, CEO of Benetti, said, “We selected Saft batteries because of their high level of performance and Saft’s flexibility to customize the mechanical design of the battery system. Saft’s marine battery technology has been adopted by some of the world’s most innovative and prestigious vessels for applications where environmental performance, safety and cost efficiency are essential.”

Siemens wins Fjord1 electric ferry contract

Image Coming Soon - 1Siemens will supply propulsion systems for two new battery ferries. Operated by Fjord1, the all-electric ferries will ply the E39 Anda-Lote route on the west coast of Norway. Both will have a cargo capacity of 120 cars, 12 trailers and 349 passengers. Operation on the 2.4km-long route will start in January 2018.

On board each of the two ferries, Siemens will install its electric propulsion solution BlueDrive PlusC, which includes lithium-ion batteries as energy storage and thruster and remote control for the propellers, an energy management system and an integrated alarm and monitoring system. The ship’s energy storage system is charged at each side of the crossing, with a shore connection to the local grid, and is monitored from the ferries based on wi-fi communication.

Currently, the ferries are operated with diesel engines. They run every 20 minutes from 06:40hrs to 22:00hrs and with reduced frequency during the night. The Anda-Lote route is the first ferry connection where the country’s Road Administration requires the use of zero-emission technology. The tender dictated that one of the ferries must be based on zero emissions and that the second could be a low-emissions ferry. Fjord1 ended up choosing two electric battery-powered ferries, giving a better overall return both financially and for the environment.

“Once the infrastructure is in place on land, it makes sense to make the most of the investments with two ferries,” said Arild Austrheim, maritime technical director at Fjord1. Therefore, we chose to go for the most environmentally friendly option.”

Royal Caribbean Cruises’ new ships to be powered by LNG and hydrogen fuel cells

Image Coming Soon - 1The newest class of ships from Royal Caribbean Cruises (RCL) will be powered by LNG and introduce the use of fuel cell technology.

The company has signed a memorandum of understanding with shipbuilder Meyer Turku for the new class of vessel under the project name Icon, and the vessels will be delivered in the second quarters of 2022 and 2024. In the meantime, RCL will begin testing fuel cell technology on an existing Oasis-class ship in 2017, and will also run progressively larger fuel cell projects on new Quantum class vessels being built in the next several years.

“We believe fuel cells offer very interesting design possibilities,” said Harri Kulovaara, RCC’s chief of ship design. “As the technology becomes smaller and more efficient, fuel cells become more viable in a significant way to power the ship’s hotel functions. We will begin testing those possibilities as soon as we can, and look to maximize their use when Icon class debuts.”

Kulovaara added that RCL has been eyeing fuel cells for nearly a decade, and believes the technology is now at a stage of development that justifies investment. “There is a long lead time for Icon class, and we will use that time to work with Meyer Turku to adapt fuel cell technology for maritime use.” He also said that additional regulatory standards would need to be developed for the technology.

Hydrogen-powered passenger ferry project under way in San Francisco Bay

Image Coming Soon - 1Sandia National Laboratories, which recently signed a cooperative research and development agreement (CRADA) with San Francisco-based company Red and White Fleet, has announced SF-BREEZE (San Francisco Bay Renewable Energy Electric vessel with Zero Emissions), a high-speed hydrogen fuel cell passenger ferry and hydrogen refueling station.

The US Department of Transportation’s Maritime Administration (MARAD) is funding a detailed feasibility study, led by Sandia, to examine the technical, regulatory and economic aspects of the project. The feasibility study will determine if it is possible to build a boat powered by hydrogen fuel cells that is both large and fast enough.

The high-speed passenger ferry would use about 1,000kg of hydrogen per day (an average hydrogen fuel cell car typically uses less than 5kg of hydrogen per week). To support the ferry and other potential users, the refueling station would have a capacity of 1,500kg a day – about twice the size of the largest hydrogen refueling station in the world. It would also be the first hydrogen refueling station to simultaneously serve land and marine uses. The feasibility study will also examine the design, location, regulatory constraints and economics of the station.

The outcome of the feasibility study will be a ‘Go/No-Go’ recommendation to proceed with the actual design and build of the ferry and hydrogen station. If the recommendation is a ‘Go’, the study will identify the best paths forward for a successful project. Sandia intends that the feasibility study, regardless of the outcome, will be useful to others nationally and around the world who are looking at hydrogen fuel cell vessels as clean energy alternatives.

ABB launches new Azipod propulsion model

Image Coming Soon - 1ABB is launching a new Azipod podded electric propulsion unit that it says is up to 10% more efficient than previous versions. The new linear flow Azipod XL features a nozzle with stator plates, which directs the water flow from the propeller to reduce the turbulence and energy loss and to give the optimum thrust for the vessel.

According to the company, Azipod XL represents the biggest jump in the systems’ fuel efficiency in recent years. In a statement, it said that “if the newest model replaced all existing Azipod units it would save the shipping industry 2.2 million tons of fuel, and 7 million tons of carbon dioxide, over the next 25 years”.

“The new Azipod XL is completely in step with the needs of the maritime industry,” said Juha Koskela, managing director of ABB’s Marine and Ports business. “Ship owners always want solutions that improve their bottom line while more stringent emission regulations are pushing operators to utilize the most efficient propulsion system possible.”

Azimuth propulsion works by drawing water into the propeller and pulling the vessel, therefore the addition of a nozzle will optimize the water flow as it leaves the propeller. All improvements have been tested extensively using scaled versions in laboratory conditions. Furthermore, Azipod XL can be designed to give high bollard pull thrust at lower speed and still have good characteristics at higher speeds.

Peace Boat and DNV GL sign Ecoship collaboration agreement

Image Coming Soon - 1Peace Boat, the Japan-based international non-profit NGO, and classification society DNV GL have signed a memorandum of understanding (MOU) to co-develop the Ecoship cruise ship.

The MOU, which was signed at this year’s SMM trade fair, will see the partners work together on the design, construction and operation phases of Peace Boat’s Ecoship and the promotion of the Ecoship as a flagship for climate action and for sustainability in shipping.

Architectural naval design company Oliver Design has based the Ecoship design on biophilic principles, incorporating cutting edge technology to improve efficiency, reduce waste and minimize environmental impacts. Some of the most notable features include: ten masts to harness wind energy for propulsion, solar panel-covered sails and a 6,000m2 topdeck solar farm, a closed-loop water system to reuse, purify and repurpose water, waste heat recovery systems where it is hoped that 80% of the energy normally lost in the air and in the water can be reclaimed for use.

“The cruise industry is growing so fast, particularly in East Asia, and the need to mitigate the environmental impact of such expansion is very important,” said Yoshioka Tatsuya, founder and director of Peace Boat. “Through its technical characteristics and in the programs that it carries out we hope it will encourage a model for 'green' cruising and further innovations in the cruise industry.”

New diesel-electric propulsion system developed for excursion vessel

Image Coming Soon - 1Emerson Electric has announced that Leroy-Somer, Control Techniques and Mayday Electronics have developed a high-performance diesel-electric propulsion system for a new Corsican excursion vessel.

The parallel hybrid system, which, according to the partnership, is at the leading edge of hybrid technology, was developed for CNB PRO, of Construction Naval Bordeaux (Bénéteau Group), and its client, Nave VA, which recently acquired a new model CNB PRO 20 Hybrid vessel.

Equipped with two 800hp motors and a Dyneo range LSRPM series permanent magnet 750-3,000rpm synchronous motor, the vessel switches to electric power in port and protected areas, with optimal efficiency achieved when operated at low speeds. In electric mode, it has a maximum speed of 8 knots and can endure 6-8 hours of operation at 6 knots. Recharging takes no longer than 6 hours and uses a harbor three-phase supply or the on-board electrical generator. The electric propulsion system also provides redundancy.

According to CNB PRO, 140 litres of fuel per hour – or 70 litres per engine – can be saved by using electric propulsion, and notes that the US$400,000 to US$455,000 investment that is involved in such a battery set can show a return on investment within less than four seasons of operation.

"The fact that the diesel engine can be shut down in order to use the electric propulsion system helps to preserve it,” said Pierre Lompech of CNB PRO. “Its service life can therefore be doubled, depending on the applications.”

Norsepower receives US$3m funding to develop world’s largest rotor sail

Image Coming Soon - 1Norsepower will receive US$3m in funding from the European Commission and the Finnish government’s funding agency for innovation, Tekes, to further research and development of its Norsepower rotor sail solution technology, including development of the world’s largest Flettner rotor.

Norsepower’s rotor sail solution is a modernized version of the Flettner rotor; a spinning cylinder that uses the Magnus effect to harness wind power to generate forward thrust. The solution is fully automated and senses whenever the wind is strong enough to deliver fuel savings, at which point the rotors start automatically.

According to the company, the new rotor sail models will be suited for tankers, bulk carriers, large ro-pax, and full size passenger vessels where smaller rotor sails would be inefficient. The new models will also be designed to be suitable for ships voyaging globally, including the northern hemisphere and Arctic regions that have not yet seen auxiliary wind propulsion despite having favorable wind conditions. A record-breaking rotor sail model is planned to be 30m in height and 5m in diameter, with a maximum main-engine equivalent power output of more than 4MW.

Funding will also support the development and inclusion of multi-functional features within the system that may have otherwise not been possible, and will accelerate the new rotor sails’ time to market, as well as supporting manufacturing, assembling, land testing, fine tuning, and piloting of Norsepower’s medium-size (24m in height x 4m in diameter) rotor sail model.

Commenting on the funding, Tuomas Riski, CEO, Norsepower said: “We are extremely grateful to Tekes and to the European Commission. Their decisions are a clear vote of confidence in Norsepower’s ability to realize the commercial potential of our rotor sail solution. We intend to use this recognition and the momentum we have now created to accelerate its development and create the world’s largest rotor sail capable of bigger emissions reductions and better fuel savings.”

Two small rotor sails are currently installed onboard Bore’s M/S Estraden, a 9,700DWT Ro-Ro carrier. Measured and independently verified by NAPA, the rotor sail solution has delivered fuel consumption reductions of 6.1%.

General Motors and US Navy collaborating on fuel cell-powered UUV

Image Coming Soon - 1General Motors (GM), the Office of Naval Research (ONR) and the US Naval Research Laboratory (US NRL) are cooperating to incorporate automotive hydrogen fuel cell systems into the next generation of US Navy unmanned undersea vehicles (UUVs).

Under the ONR’s Innovative Naval Prototype program for Large Displacement UUVs, energy is a core technology in the US Navy’s goals for vehicles with more than 60 days’ endurance. The US NRL recently concluded an evaluation of a prototype UUV equipped with a GM fuel cell at the heart of the vehicle powertrain. The tests, a key step in the development of an at-sea prototype, were conducted in pools at the Naval Surface Warfare Center in Carderock, Maryland, USA.

“Our in-water experiments with an integrated prototype show that fuel cells can be game changers for autonomous underwater systems," said Frank Herr, ONR's department head for Ocean Battlespace Sensing. "Reliability, high energy, and cost effectiveness — all brought to us via GM's partnering — are particularly important as the US Navy looks to use UUVs as force multipliers."

Fjord1 orders two battery-powered ferries from Tersan Shipyard

Image Coming Soon - 1Norwegian ferry owner and operator Fjord1 has signed a newbuilding contract with Turkey-based Tersan Shipyard for two battery-powered ferries. The two vessels – co-developed by Norwegian ship design company Multi Maritime – are expected to commence operation from January 1, 2018, until 2027 on E39 Anda-Lote on the west coast of Norway.

“This will be the first ferry connection in Norway where the Road Administration requires use of zero-emission technology,” said Fjord1 in an official statement. “The new ferries are an important step towards more environmental friendly public transportation.”

Charging of the batteries will be made through fully automatic charging stations at the quayside. Battery capacity is expected be sufficient to continue operations for several hours without charging, for example during maintenance on grid or charging stations. In addition, the ferries will be equipped with biodiesel generators, which will enable potential operation as plug-in hybrids on other fjord crossings in the future. The ferries’ cargo capacity is 120 cars, 12 trailers and 349 passengers each. Construction of the two ships is scheduled to begin in October this year.

CUNY hybrid research vessel update

Image Coming Soon - 1Construction of the second vessel in a series of hybrid aluminum catamaran research vessels is underway at Derecktor’s New York shipyard. The 65m-long vessel, commissioned by The City University of New York (CUNY), in collaboration with the Science and Resilience Institute at Jamaica Bay (SRI@JB), will be operated out of Jamaica Bay, New York and will be used for research and educational purposes.

The design's hybrid propulsion system provides a battery-powered vessel with a variable speed diesel generator to recharge the batteries. A BAE Hybridrive system utilizes Corvus Energy lithium-polymer batteries to power an AC traction motor, which provides power to the shaft/propeller. As the batteries are drained the variable speed diesel generator turns itself on and off as needed, based on demand and state-of-charge of the batteries. The system also provides electrical power for hotel loads onboard the vessel. To minimize impact on the local waters, keel coolers will be used to reduce the wastewater discharge from the vessel.

"Given the versatile electrical source for hotel loads we have the perfect platform for high electrical demand applications,” said Micah Tucker, general manager, Derecktor, New York. “We also have seen increased interest given the silent operation of the electric motors. This proves to be a major contributor to the vessel's appeal to researchers.”

The build will take approximately 16 months with delivery anticipated in June 2017.

Hybrid engine to power Venetian water taxis

A diesel-electric powertrain for Venice water taxis is being developed by engineers from the University of Southampton to provide environmentally-friendly transport in the UNESCO World Heritage city.

Working with REAPsystems, a UK-based developer of advanced propulsion systems, the engineers are creating a diesel-electric engine that can be installed by any boat builder and fitted into all existing boats. The system uses the latest diesel engine technology paired with a high-power electric motor and inverter as well as a lithium-ion battery and advanced system control unit.

In the city, the vessel can be operated by pure electric power. During medium to high speed operation, the diesel engine automatically takes over. During diesel operation, the electric motor works as a generator, recharging the batteries and pushing the engine into a more efficient operation. The electric motor may also assist to reduce exhaust emissions.

Professor Suleiman Sharkh, head of mechatronics at the University of Southampton, said: "The benefits are clear: no noise, no pollution, no vibrations when operating in the city. Our demonstration with the water taxi will inform the local authorities, so they can tighten their regulations. Thus, the reduced maintenance cost and the halved fuel consumption will convince operators to switch to these green engines."

The hybrid taxi will be tested this summer to coincide with new legislation concerning pollution from waterborne traffic. A crowdfunding project has been launched to fund the development of the technology.

Delivery of Texelstroom hybrid ferry

Image Coming Soon - 1Following an agreement more than two years ago with northern Spanish shipyard LaNaval for the construction of a new ferry, Texelstroom, one of the world's first hybrid RoPax-ferries, has been delivered to Koninklijke N.V. Texels Eigen Stoomboot Onderneming (Royal TESO).

The vessel, which will transport up to 1,750 passengers and 350 vehicles between the port of Den Helder and the island of Texel, is powered by four Anglo Belgian Corporation-supplied main engines, comprising two dual fuel (CNG + diesel) generator sets that provide 2MW each at 1,000rpm and two diesel generator sets that each develop 2MW at 750rpm.

The 135m-long ferry will sail using its dual fuel engines every hour between 6am and 10pm. The engines have sufficient power in this tidal region for the approximately 20-minute crossing between the mainland and the largest Dutch Wadden Sea Island Texel. In normal weather conditions, Texelstroom will use only one dual fuel generating set during the majority of the crossing wherein the engine cooperates with the battery packs on board.

Redundancy was taken into account from the concept stage of the ferry. In cases of extreme urgency, the hybrid ferry can make the crossing from Texel to the mainland (and vice versa) at high speed. Therefore, two back-up diesel generating sets were also provided.

In addition, a 700m² solar photovoltaic panel field is installed on the roof of the ferry. The energy is stored in high capacity batteries that are part of the advanced energy management system. The energy can then be used at peak times for propulsion or onboard electricity consumption.

Cees de Waal, director of TESO, said: "With Texelstroom, TESO wanted to achieve its ambition where environmental benefits, cost control and quality improvement go together. The ship embodies the latest technologies for reducing emissions. This next-generation ferry will sail our passengers in a comfortable and efficient way across the Marsdiep. With regards to the propulsion, it was very important to choose environmentally friendly and reliable engines."

Yamaha Motor develops autonomous electric survey craft

Image Coming Soon - 1Yamaha Motor has announced the development of BREEZE10, an autonomous unmanned compact electric survey craft designed to support sounding work such as measuring the sediment levels of dams.

According to the company, BREEZE10 is an electric FRP craft measuring approximately 3m in length that enables easy mounting of measurement equipment such as narrow multi-beam sonar, which is becoming increasingly popular in measurement work, including domestic dam silt level measurement.

Operation in shallow locations is possible due to a special-purpose hull fitted with a Yamaha Motor 0.5kW electric motor, while a lithium-ion battery and onboard compact generator provide six hours of continuous operation. Three operating modes can be selected to suit the environment of the survey location: programmed auto-navigation mode, remote-controlled operation mode, and on-board joystick operation mode.

BREEZE10 uses GNSS (a satellite positioning system) positioning data and azimuth angle data, which allows unmanned autonomous navigation and, says Yamaha Motor, supports improvements in efficiency and labor-saving efforts for surveying the beds of bodies of water using sonar. Usage of the craft is expected to expand from the surveying field into surveillance and defense support in the future.

Norwegian Electric Systems launches new DC grid solution

Image Coming Soon - 1Norwegian Electric Systems (NES) has launched Odin’s Eye, a brand new DC grid solution that allows for the use of variable speed generator sets. It can be used in any vessel that requires a diesel-electric propulsion system, while batteries and shore connections can also be added. It features high levels of redundancy and ultra-rapid short circuit protection.

“We have always believed in DC grid solutions, they work, they save fuel use and have lower emissions,” said Paul Winson, senior vice president sales for NES. “However, we did not like the technology currently being offered because it was very expensive and limited in what it could do. We knew we could do better, so we set about finding a solution that is less expensive and offers more capability, including improved safety. It turns out we had the answer already.”

According to Winson, NES expanded its Quadro Drive frequency converter and connected it in a ring net solution. “Instead of being limited to just a two split switchboard, which means drastically over sizing the generators and propulsion motors, we can now split all the essential equipment up into separate autonomous islands. These islands can be configured to work together with closed bus-ties or independently with open bus-ties. Because we are using our existing well proven hardware we can keep our costs very low and avoid the risk of ‘new product development’.”

EST-Floattech introduces bulletproof nanotechnology batteries

Dutch lithium polymer energy storage system manufacturer EST-Floattech has announced Green Dolphin, a new product comprising fabricated Li-NMC batteries that employ technology on a nanoscale.

Originally developed by Kokam for defense applications such as submerged vessels, EST-Floattech is now commercializing nanotechnology for the marine industry due to the chemistry’s reported stability. According to the company, nanotechnology combines the energy density of Li-NMC and the extreme stability of Li-LTO, resulting in a cell that is supposedly almost immune to short circuits and overcharging.

Unlike conventional lithium cells, which build up a passive film on the surface of the anodes and cathodes – known as solid electrolyze interphase – that results in reduced conductivity, Green Dolphin’s cells are coated in nano-sized LFP and Nlto particles, which reportedly improve the conductivity of the lithium-ion electrodes, stabilizes performance and results in a longer life cycle.

Green Dolphin, a 14 x 2000Ah cell, is said to offer a cycle life of more than 6,000 cycles even at 100% depth of discharge. It has undergone various tests to prove its safety and functionality, including a ballistic test with a bullet fired at the pack, and several needle tests to induce short circuits. EST-Floattech claims that neither test stopped the cell from functioning and didn’t result in thermal runaway.

“In our efforts to develop the most stable and intelligent energy storage solution possible we are bringing nanotechnology to the marine industry’s commercial applications,” said Marco de Bos, managing director of EST-Floattech. “Green Dolphin has all the characteristics of a highly safe and long cycle life energy storage solution.”

The company expects to deliver Green Dolphin to the market by Q4 2016.

Zumwalt will then transit to its home port in San Diego, where mission systems activation will continue in parallel with a post-delivery availability.

First Caterpillar hybrid thruster ready for delivery

Image Coming Soon - 1Caterpillar Marine has announced that it is overseeing the delivery of its first hybrid thruster system to an undisclosed shipyard in Singapore. The system will be commissioned mid this year.

According to the manufacturer, the new propulsion set-up “outperforms diesel mechanical systems in all partial load conditions, and offers improved fuel economy and substantial through-life savings for a variety of offshore support vessels. For vessels spending a high amount of time in standby or DP service, the annual fuel savings can be as high as 35% – calculated across the entire operating profile of the vessel”.

The hybrid thruster system can also be used to downsize a vessel’s main engine so that engine load is optimised; it also allows the vessel to switch to diesel-electric mode for low DP operations or in standby. Caterpillar Marine says it believes the thruster represents “a significant new market contender, either for retrofit or installation at new-build stage”.

Jonas Granath, manager electrical design, Caterpillar Marine Solution Center, said, “With this new system, OSVs with DP will be able to use the diesel-electric mode and run off the smaller gensets with the propellers operating economically at a very low rpm. It is in exactly these conditions where our new marine hybrid thruster system offers the greatest benefits.”

Offshore Ship Designers introduces low-emission hybrid Azistern e-tug

What makes this particular Azistern tug different is that it is driven by a revolutionary podded drive and has a flexible and green electro/diesel-electric configuration.”

The hybrid power of the 22m LOA/50-ton BP Azistern-e is generated by two 970kW variable-speed gensets and supported by two 400kWh lithium battery packs. The low-emission tug can be delivered compliant with IMO Tier 3 requirements with an aftertreatment system suitable for ECA areas, and is also equipped with an energy management system. The uniform and optimised loading of the propulsion system has been designed to ensure low maintenance and fuel costs. Transient sailing and manoeuvring can be performed using the batteries with zero emissions.

New Rolls-Royce thrusters feature weight-saving carbon-fibre material

Image Coming Soon - 1A new generation of steerable thrusters being delivered to Italian yacht builder Benetti by Rolls-Royce makes extensive use of carbon-fibre material for the first time.

Designed initially for fast yachts, with further applications in passenger vessels and workboats, the new Azipull Carbon 65 (AZP C65) uses carbon fibre for load-carrying parts, resulting in a reduction of the propulsion system’s weight and a better vessel layout.

The first thruster in the series, AZP C65, is designed for a power rating of 2MW and fitted with a fixed pitch, pulling type propeller – meaning the propeller faces forward. The driveline is designed with two spiral bevel gear sets, installed in a supporting structure that ensures optimum load-carrying capacity in all operating conditions. The thruster can be steered using a hydraulic system.

Gary Nutter, Rolls-Royce EVP propulsion and engines, said, “This new development has greatly benefitted from the very good cooperation we have had with Azimut Benetti. Their skills as a yacht builder and their engagement with us in creating the perfect vessel are an inspiration.”

Taiwan’s largest shipyard places order with Siemens for advanced diesel-electric propulsion system

Image Coming Soon - 1 CSBC Corporation Taiwan has chosen Siemens to supply high-tech diesel-electric propulsion systems and other accessories for four 65,000-ton semi-submersible deck cargo vessels (SSDCVs).

The country’s largest shipyard is building the vessels for a customer in Singapore. Compared with conventional mechanical propulsion technologies, Siemens’ diesel-electric system will reduce fuel costs by up to 15% as a result of unique power management features. Likewise, associated propellers, rudders and thrusters will improve the vessel’s manoeuvrability when operating at low speeds. Each propulsion system includes an IDS comprising low-voltage propulsion motors and frequency converters that facilitate economic, energy-saving vessel operation, as the components are perfectly matched to each another. To protect the ocean from unnecessary pollution, ballast pump systems will help control and dispose of pollutants effectively.

“Our state-of-the-art diesel-electric propulsion systems are designed to enhance the fuel efficiency and manoeuvrability of marine vessels, while leveraging an associated pumping technology to protect the surrounding environment,” said Mario Azar, CEO of the Siemens Oil & Gas and Marine business unit. “We are pleased to be working closely with CSBC Corporation Taiwan on this important project, and with the overall adoption of our propulsion system in the oil and gas and marine industries we serve.”

Siemens will supply the complete diesel-electric propulsion systems for all four SSDCVs, to be delivered by the end of 2017. Each system, consisting of four 4,000kW low-voltage Simotics motors and four low-voltage Sinamics frequency converters as well as their corresponding transformers, creates an IDS. Due to optimum coordination of components, a cost-effective overall system has been developed that is distinguished by reliable operation and high availability. The scope of supply for each vessel also includes 6,980kW main generators, medium-voltage switchboards, power management systems, converters and transformers for ballast pump as well as distribution transformers, a controllable pitch propeller, flap rudder and a bow and stern tunnel thruster.

Leading marine propulsion developer set for takeover

Image Coming Soon - 1 International trading company Pon Holdings and private equity firm Parcom Capital have announced they’ve reached an agreement on the takeover of Imtech Marine. The details of the acquisition are currently being worked out.

After the takeover, Imtech Marine will continue to operate independently. Pon Holdings has built a great deal of international expertise in the maritime and offshore sectors, and Parcom Capital has been an active investor in these sectors.

Vard trawler to feature state-of-the-art Rolls-Royce hybrid technology

Image Coming Soon - 1 Norwegian shipbuilding company, Vard Group, has announced that Rolls-Royce will design and equip its new shrimp stern trawler, in a contract worth in excess of US$9m to the British engineering organisation.

The vessel, which has been ordered from Vard by a Canadian company, is of Rolls-Royce NVC 374 design and will be around 79m long, featuring an ICE 1A ice class hull. It will be equipped with a wide range of Rolls-Royce equipment, including a B33:45 main engine, Promas propulsion, and a power electric system with hybrid shaft generator (HSG). The Rolls-Royce package also includes a tunnel thruster, automation and winches.

The new vessel will be equipped with fishing winches driven by permanent magnet (PM) engines. The contract represents the first commercial sale of this innovative technology developed by Rolls-Royce. PM technology was first launched by Rolls-Royce to drive thrusters more efficiently, silently and with less vibration. The PM winch engine is particularly suited to applications that operate in harsh conditions and combine a need for sensitive control and rapid changes in pull and speed. Operational efficiency in ice, low emissions, crew comfort, safety and excellent seakeeping capabilities have been the main considerations in the development of the ship design and complete equipment package.

“Our ship design capability and advanced equipment help build the most effective and modern fishing vessels in the world,” said Monrad Hide, Rolls-Royce VP for special-purpose vessels. “Decades of world-class research, development and industry knowledge combined with close cooperation with our customers allow us to help them maximise the efficiency of their fishing operations. We’re delighted to once again be working with Vard on the construction of a sophisticated and highly capable vessel, and to also secure another contract for our new B33:45 engine, which is gaining popularity across a range of vessels since we launched it last year.”

The HSG is an advanced electric power control system for conditioning the electrical power coming from a shaft generator. It allows shaft speed to be reduced while maintaining a constant frequency for the electrical supply throughout the ship. This permits a much more flexible use of engine and propeller speed variations to maximise propeller and engine efficiencies by running them at their design points. This also has the benefit of improving fuel efficiency, reducing emissions and significantly reducing operating costs.

Wartsila and Cavotec to develop world’s first marine wireless charging and mooring concept

An agreement has been signed between Wärtsilä and Cavotec to jointly develop the world’s first combined induction charging and automatic mooring concept. The new project’s integrated system will be capable of transferring more than 1MW of electrical energy – some 300 times more than that of current chargers used by electric cars.

According to the OEM, wireless charging eliminates the cable connection between the vessel and shore, thereby securing and facilitating safe connections and disconnections. Wärtsilä adds that it also reduces maintenance, since wear and tear to physical connection lines is eliminated. Similarly, damage to electrical outlets caused by seawater, snow and ice is also avoided.

Cavotec’s mooring system is a vacuum-based automated mooring technology that eliminates the need for conventional mooring lines. Remote-controlled vacuum pads recessed into, or mounted on, the quayside, moor and release vessels in seconds.

“During recent years, wireless charging has been introduced for cars, buses and trains. Wärtsilä has now made this possible for marine vessels,” said Peter Rogers, director power products, Wärtsilä Marine Solutions. “This agreement with Cavotec will enable this technology to be delivered as an integrated charging and mooring system.”

Transfluid hybrid drivetrains to power German shipyard’s new vessels

Italian power transmission manufacturer, Transfluid Trasmissioni Industriali, has announced that it will produce hybrid drivetrains for yachts built by Bavaria Yachtbau, one of Germany’s largest shipyards and builders of catamarans and motorboats.

The Transfluid system consists of a hybrid module that integrates the clutch on which the electrical machine is mounted and connects directly to the flywheel of a diesel engine. The first vessel from Bavaria Yachtbau to be fitted with the system will be the new semi-displacement motor yacht Bavaria E40.

Testing of the first prototype will take place this spring, and the finished vessel is scheduled to be made available at the end of 2016. The addition of the hybrid drivetrain will enable Bavaria E40 to operate in diesel, pure-electric and diesel-electric mode during navigation at the push of a button.

“Bavaria Yachtbau has revolutionised yacht building in many ways in recent decades,” said Fabio Marcellino, product manager for the new Bavaria E40. ”Now, thanks to this collaboration with Transfluid, it has created the possibility to offer innovative, eco-friendly boats with hybrid propulsion for yachts for series production.”

This, according to Derecktor, will make the vessel suitable for use in highly sensitive research applications and create “one of the most forward-thinking and environmentally friendly vessels in operation today”.

Wärtsilä announces plans for zero-emissions ferry concept

A complete concept for a series of zero- and low-emissions shuttle ferries is being launched by Wärtsilä.

The concept has been developed by the OEM’s ship design and electrical and automation offices. The ferries are designed to run entirely on batteries or in a battery-engine hybrid configuration where the fuel options are LNG or biofuel. According to Wärtsilä, in plug-in operation the fuel consumption is reduced by 100% compared with conventional installations, and all local emissions are completely eliminated. With the plug-in hybrid configuration, emissions are reportedly reduced by up to 50%.

The concept features the company’s new wireless inductive charging system, eliminating physical cable connections and thus reducing wear and tear and enabling charging to begin immediately when the vessel arrives at quay.

The design also encompasses a complete electrical and automation package based on the company’s battery/hybrid solution. It also includes Wärtsilä azimuth propulsion units and a complete bridge control system. The ferry series can accommodate 60 to 120 cars on a single car deck.

ABB to power futuristic hybrid ferry on Norwegian fjords

Leading power and automation technology group, ABB, will provide a compact and lightweight version of its Onboard DC Grid system to a brand-new ferry concept that will operate on the Norwegian fjords.

Named Seasight, the futuristic-looking vessel, which is being built by Brødrene Aa, will carry up to 400 passengers between Flåm and Gudvangen along the Nærøyfjord in the west of Norway, a distance of around 32km.

ABB’s bespoke version of its maritime hybrid solution will manage and control the energy flow between the diesel engine, propeller and charging station. The Onboard DC Grid is designed to efficiently integrate energy storage into modern marine power systems through its DC infrastructure and integrated power and energy management system. In the case of Seasight, the Onboard DC Grid will transfer energy to the battery during charging, which will happen at both ends of the voyage, and while the diesel engines are running.

Once the ferry has arrived in the most scenic part of the fjord, it will switch to battery power, operating in almost complete silence at around 10 knots (approximately 18km/h). The Nærøyfjord, which is on UNESCO’s World Heritage List, remains largely unspoiled by human development and the ferry is designed with the surroundings in mind. Seasight will complete around 700 journeys a year for its owner, The Fjords, from May 2016.

“Regulation means Norway is leading the world in terms of battery power for passenger ferries,” said Sindre Sætre, ABB’s director of marine and ports in Norway. “Globally, battery power and hybrid technology are gaining importance in the maritime sector and we are delighted to be at the forefront of that process.”

The ferry design is inspired by a trail finding its way up a steep mountainside. It measures 40m in length and 15m in width. Outside the ferry, passengers will be able to climb all over the boat; the inside will feature panoramic views and 450 seats. The construction of the carbon-fibre vessel is already under way at Brødrene Aa, which also came up with the concept.

PBES announces world’s first commercialised thermal runaway suppression system

Battery storage system manufacturer PBES has announced what it describes as the world’s first ever commercialised thermal runaway suppression system. The new innovation – which represents the first fire-safe lithium battery system, managing safety at the cell level – is said to be capable of suppressing and preventing the effect of cascading thermal runaway including in systems that have sustained significant physical damage.

“The historic challenge for lithium batteries has always been that they can catch fire,” said Brent Perry, chief executive of PBES. “No more. Our team has developed a solution that effectively stops thermal runaway.”

The system is an industry first in terms of fire-safe lithium battery systems, and PBES claims that it solves the universal problem of safety, effectively removing a significant barrier in the marketplace. In multiple tests, without a single failure, PBES says it has demonstrated

kilowatt to megawatt scalability to control and eliminate thermal runaway. According to the company, until now thermal runaway mitigation in a commercially available product has never been achieved. Massachusetts Institute of Technology (MIT) is said to have successfully stopped thermal runaway, but this was in a lab setting using liquid nitrogen for cooling.

The incorporation of the patent-pending Thermal-Stop, CellCool and E-Vent systems, combined with the advanced energy management system, reportedly provides safety and protection from the cell level up to the system level, which PBES says leads to results that have never been achieved by competing lithium battery technologies.

“The harder a system works, the better energy storage can support it, and the faster the customer’s return on investment,” said Perry. “Modelled on the standards of the IEC and the third-party class group type approval criteria of DNV-GL, Lloyd’s Register and American Bureau of Shipping, PBES engineered solutions are the template for energy storage for the next 20 years.”

PBES lithium battery storage is suitable for renewable energy-to-grid, grid-based systems, industrial marine, port machinery, commercial transportation, data centre UPS, defence and homeland security, island and other off-grid or remote community applications. PBES solutions are currently offered with NMC and titanate cell chemistry, with performance starting at 3C RMS, and lifespan up to 10 years. Payback is typically within one to three years.

Japanese NGO reveals plans to develop world’s greenest cruise ship

Taiwan’s largest shipyard places order with Siemens for advanced diesel-electric propulsion system

CSBC Corporation Taiwan has chosen Siemens to supply high-tech diesel-electric propulsion systems and other accessories for four 65,000-ton semi-submersible deck cargo vessels (SSDCVs). The country’s largest shipyard is building the vessels for a customer in Singapore. Compared with conventional mechanical propulsion technologies, Siemens’ diesel-electric system will reduce fuel costs by up to 15%, due to unique power management features. Likewise, associated propellers, rudders and thrusters will improve the vessel’s manoeuvrability when operating at low speeds.

Each propulsion system includes an IDS comprising low-voltage propulsion motors and frequency converters that facilitate economic, energy-saving vessel operation, as the components are perfectly matched to one another. In order to protect the ocean from unnecessary pollution, ballast pump systems will help effectively control and dispose of pollutants.

“Our state-of-the-art diesel-electric propulsion systems are designed to enhance the fuel efficiency and manoeuvrability of marine vessels, while leveraging an associated pumping technology to protect the surrounding environment,” said Mario Azar, CEO of the Siemens Business Unit Oil & Gas and Marine. “We are pleased to be working closely with CSBC Corporation Taiwan on this important project, and with the overall adoption of our propulsion system in the oil and gas and marine industries we serve.”

Siemens will supply the complete diesel-electric propulsion systems for all four SSDCVs, to be delivered by the end of 2017. Each system, consisting of four 4,000kW low-voltage Simotics motors and four low-voltage Sinamics frequency converters as well as their corresponding transformers, creates an IDS. Due to optimum coordination of components, a cost-effective overall system has been developed that is distinguished by reliable operation and high availability. The scope of supply for each vessel also includes 6,980kW main generators, medium-voltage switchboards, power management systems, converters and transformers for ballast pump as well as distribution transformers, a controllable pitch propeller, flap rudder and a bow and stern tunnel thruster.

Leading marine propulsion developer set for takeover

International trading company Pon Holdings and private equity firm Parcom Capital have announced they’ve reached an agreement on the takeover of Imtech Marine. The details of the acquisition are currently being worked out.

Analysts say the advent of the new shareholders guarantees the continuity of Imtech Marine after its parent company, Royal Imtech, went bankrupt. Pon and Parcom say the takeover will allow the marine tech developer to realise its growth ambition, as well as safeguarding jobs, current orders for global customers and existing R&D projects.

René ten Brinke, director for global services at Imtech Marine, said, “We are extremely happy with Pon Holdings and Parcom Capital as the new owners of Imtech Marine. Both are highly professional companies, with extensive experience in the maritime industry; it couldn’t have been a better scenario for us. This new ownership aligns perfectly with the positive developments that have already been set in motion within Imtech Marine and will also further strengthen and accelerate the growth of our business.”

Imtech Marine employs nearly 2,500 staff at almost 100 offices in 30 countries, close to shipbuilding centres and along the shipping routes. After the takeover, Imtech Marine will continue to operate independently. Pon Holdings has built a great deal of international expertise in the maritime and offshore sectors, and Parcom Capital is an active investor in these sectors.

Vard trawler to feature state-of-the-art Rolls-Royce hybrid technology

Norwegian shipbuilding company, Vard Group, has announced that Rolls-Royce will design and equip its new shrimp stern trawler, in a contract worth in excess of US$9m to the British engineering organisation.

The vessel, which has been ordered from Vard by a Canadian company, is of Rolls-Royce NVC 374 design and will be around 79m long, featuring an ICE 1A ice class hull. It will be equipped with a wide range of Rolls-Royce equipment, including a B33:45 main engine, Promas propulsion and a power electric system with hybrid shaft generator (HSG). The Rolls-Royce package also includes a tunnel thruster, automation and winches.

The new vessel will be equipped with fishing winches driven by permanent-magnet (PM) engines. The contract represents the first commercial sale of this innovative technology developed by Rolls-Royce. PM technology was first launched by Rolls-Royce to drive thrusters more efficiently, silently and with less vibration. The PM winch engine is particularly suited to applications that operate in harsh conditions and combine a need for sensitive control and rapid changes in pull and speed.

Operational efficiency in ice, low emissions, crew comfort, safety and excellent seakeeping capabilities have been the main considerations in the development of the ship design and complete equipment package. “Our ship design capability and advanced equipment help build the most effective and modern fishing vessels in the world,” said Monrad Hide, Rolls-Royce VP for special-purpose vessels. “Decades of world-class research, development and industry knowledge combined with close cooperation with our customers allow us to help them maximize the efficiency of their fishing operations.

“We’re delighted to once again be working with Vard on the construction of a sophisticated and highly capable vessel, and to also secure another contract for our new B33:45 engine, which is gaining popularity across a range of vessels since we launched it last year.” The HSG is an advanced electric power control system for conditioning the electrical power coming from a shaft generator. It allows shaft speed to be reduced while maintaining a constant frequency for the electrical supply throughout the ship. This permits a much more flexible use of engine and propeller speed variations to maximise propeller and engine efficiencies by running them at their design points. This also has the benefit of improving fuel efficiency, reducing emissions and considerably reducing operating costs.

MARAD confirms hydrogen fuel cell ferry investment

The US Department of Transportation’s Maritime Administration (MARAD) has announced that it is providing US$500,000 to support a feasibility study for the design, construction and operation of a high-speed passenger ferry powered by hydrogen fuel cell technology and a hydrogen refueling station.

The fuel cell would provide power for the ferry’s propulsion and auxiliary electrical systems, and the hydrogen refueling station – which would be the largest in the world – would service the ferry, electric cars, buses and fleet vehicles, and other maritime vessels powered by fuel cells.

“This study is just one more way in which MARAD is working to find new and efficient technologies for use in the maritime industry that offer clean-fuel options to cut emissions,” said maritime administrator Paul Jaenichen. “The US maritime industry can play an important role in reducing the world’s carbon dioxide emissions and creating a more sustainable future for us all.”

MARAD has partnered on this project with Sandia National Laboratories of the US Department of Energy (DoE), which will lead the research effort. The study will examine the technical, regulatory and economic aspects of a high-speed hydrogen fuel cell vessel as a clean energy alternative.

This study is also part of ongoing work by MARAD’s Maritime Environmental and Technical Assistance Program (META) and the maritime industry to conduct research, testing, validation and documentation of fuel cells for marine applications. The work complements an ongoing joint project to demonstrate fuel cells to provide auxiliary power for other port and shipboard applications such as powering refrigerated containers and replacing diesel generators. Furthermore, MARAD is funding an effort to demonstrate a fuel cell for ship auxiliary power for its school ship Kennedy, which is used by Massachusetts Maritime Academy as a training vessel.

The META Program is administered by the Maritime Administration’s Office of Environment and designed to foster collaboration with maritime stakeholders to address emerging environmental challenges.

Saft secures important Li-ion battery contract with ImTech and CMAL

Leading battery development company, Saft, has announced it has won a key contract to supply state-of-the-art lithium-ion battery systems to Imtech Marine. The deal will see two Saft Seanergy systems at the heart of the diesel-electric hybrid propulsion system and energy management unit for Hybrid III, the roll-on roll-off (RORO) passenger and vehicle ferry designed for use on Scotland’s short sea crossing routes around the Clyde and Hebrides.

The new vessel, currently under construction by Ferguson Marine Engineering for CMAL, will be Scotland’s third hybrid ferry when it enters service later next year, carrying up to 150 passengers and 23 cars or two HGVs. It is being funded by the Scottish Government to help meet the target set in its Climate Change Delivery Plan to reduce CO2 emissions in the transport sector by at least 20% by 2020. It will have a service speed of nine knots; because it uses both diesel and electric power, its fuel consumption will be lower than a conventional ferry, leading to fuel and CO2 emissions that are at least one fifth lower than a conventional arrangement.

For Saft, the project represents a significant development: it is the company’s first contract with Imtech Marine, a leading supplier of hybrid propulsion systems for all types of vessels around the globe.

As a modular system, Seanergy can be scaled to meet any requirements up to 750V. The modules are based on Saft’s Li-ion Super Phosphate (SLFP) cell chemistry, which offers the advantage of improved high energy capability and optimized total cost of ownership when compared with standard Li-ion phosphate technologies. In January 2015, marine industry independent safety assessor Bureau Veritas delivered the highest quality assessment for the Seanergy modules, establishing that the design conforms to recognized industry quality and certification standards.

The two Seanergy systems, which provide a total of 800kWh of energy storage, can power the vessel in battery mode only and in hybrid mode in combination with a diesel generator. The batteries will be charged overnight from shore supply while the ferry is in port. When at sea, Imtech’s energy management system will balance the energy delivered by the diesel genset and battery systems to make propulsion as efficient and clean as possible, enabling the genset to run at peak efficiency.

MTU and Akasol create battery development partnership

MTU Friedrichshafen has formed a close development partnership with Darmstadt-based Akasol to develop and deliver battery systems for MTU’s hybrid and e-drive propulsion systems.

With the help of engineering know-how from Akasol, MTU, a company that’s part of Rolls-Royce, hopes to extend its current product range with hybrid propulsion systems for mobile applications in the marine, heavy-duty ground vehicle and rail sectors.

“I am very pleased that with MTU we have found an expert partner and one of the world’s most important manufacturers of propulsion systems,” said Lothar Holder, executive managing director of Akasol. “This partnership gives us completely new opportunities to further the development of high-performance lithium-ion battery systems. For us, this is a quantum leap.”

Christos Ramnialis, vice president of sales, service and network at MTU, added, “Since our companies have already cooperated together for several years, we are very pleased and looking forward to a closer cooperation between MTU Friedrichshafen and Akasol.”

GE Marine powers and propels next generation of UK navy vessels

GE Marine has been awarded a contract by BAE Systems to supply electrical power and propulsion to the first three Type 26 Global Combat Ships for the UK Ministry of Defence (MoD).

Type 26 Global Combat Ships are, according to GE Marine, multi-mission warships capable of joint and multinational operations across the full spectrum of warfare and defence, including complex combat operations, counter-piracy, and humanitarian and disaster relief work.

“Following on from the Type 26 Design, Development and Assessment (DDA) contract awarded to GE last year, we are pleased to continue the collaborative work to deliver a cost-effective power and propulsion system for the programme. Given GE’s track record in equipping vessels with proven naval designs, we have confidence in GE Marine as a reliable partner,” said Geoff Searle, Type 26 Global Combat Ship program director, BAE Systems Naval Ships.

Customers will reportedly benefit from an energy-efficient, robust and low-noise solution thanks to the use of advanced anti-vibration technology. The naval design, an arc-proof version of GE’s MV3000 marine converter, provides the variable-speed drive, reportedly enhancing safety, performance and maturity in the power and propulsion system.

GE also plays a role in de-risking the programme by testing its power and propulsion system at GE’s Marine Power Test Facility.

Nicholas Smith, marine solutions director, GE Power Conversion, said, “Built on the back of our latest products and technology supplied to the Type 45 Destroyers and QE Class aircraft carriers, we are excited to be playing a role in the new generation of combat ships. We are committed to delivering energy-efficient electrical power and propulsion solutions that will meet the future of naval capability.”

Visedo and Electric Power Conversion win Damen Eco-Liner propulsion contract

Finnish electric drivetrain specialist Visedo has won the order for the propulsion drivetrain of the Damen Eco-Liner. Visedo, together with its marine technology partner Electric Power Conversion, will deliver the Eco-Liner’s propulsion system consisting of 4 pcs 285kW LNG gensets and two pcs Visedo 500kW direct drive propulsion motors, hotel converters, bow thruster inverters and cargo pump inverters, as well as the SmoothTHRUST control algorithm.
Thanks to the heavy-duty design of Visedo’s PowerDRUM permanent-magnet motor and generators as well PowerMASTER inverters, the machine room layout for the vessel is not complex, with the generator and propulsion inverters placed directly into the electrical machine rather than in traditional large converter panels.

Power distribution from generators to propulsion will be done using the Visedo DC-bus distribution solution that was recently tested and approved by Bureau Veritas. The Visedo DC-distribution panel ensures a fully redundant and selective solution where any fault or short circuit condition is handled without compromising the functionality of the remaining installation, therefore allowing PS and SB systems to be constantly connected together.

By using the SmoothTHRUST algorithm for power generation and load sharing, full control of energy is achieved and all harmful effects to propulsion train and generator plant are avoided, resulting in a very stable generation and propulsion system that is immune to sudden loss of power.

The Eco-Liner is Damen’s new concept for an LNG-powered low-emission inland vessel that will reduce operational costs by at least 15%. It will be delivered during 2015.

Using permanent-magnet machines for generators and propulsion, the Visedo Marine drivetrain helps achieve this target due to its very high overall efficiency at a wide speed range.

Gearless torque drive breakthroughs

At this year’s Electric & Hybrid Marine World Expo, Torque Marine and its Dutch cooperation partner company, Sandfirden Technics, presented the very latest developments in gearless torque drives, and featured a Scania DI-16 natural gas engine connected with a watercooled permanent-magnet torque generator at the event.

Low operating costs, precise manoeuvring and a high starting torque at the lowest propeller speed, as well as low-noise operation, are some of the advantages of the technology.

In 2010, Torque Marine developed an advanced High Torque Power Drive (HTP) system, an innovative diesel-electric propulsion unit for all kinds of propulsions, including river-, coastal- and tugboat applications, bettering conventional applications with combustion engines and reduction gears.

After extensive research and development work, together with the development centre for ship technology, DST, in 2010 Torque Marine successfully converted a twin-propeller river freighter, the MV ENOK, with a Torque Drive System. With a length of 84m and a width of 9.5m, the ENOK can load 1,500 pieces of cargo at a load draft of 2.86m.

ENOK is one of the first motor vessels to have been equipped with a permanent-magnet motor as a gearless electrical direct drive. Since 2010, the vessel has been running in regular cargo service operations on European waterways.

Variable masterpiece from Cummins

Cummins was at Electric & Hybrid Marine World Expo, presenting the recently announced QSK50 engine that’s been optimised for variable-speed diesel-electric (VSDE) applications.

The QSK50 has been used in fixed-speed diesel-electric applications, as well as traditional propulsion and power generation, since its launch in 2006. Early reports published by system integrators show significantly reduced fuel consumption, reduced CO2 emissions and lower system weight for the complete VSDE package, compared with fixed-speed diesel-electric gensets.

Ready, genset, go

Volvo Penta will present an off-the-shelf marine genset at this year’s Electric & Hybrid Marine World Expo, underlining its many years’ involvement in diesel-electric and hybrid propulsion solutions. The D13 MG offers low fuel consumption (around 192gr/kW at 1,500rpm) as well as low emissions. Other benefits include standard worldwide service and documentation available in advance.

The company believes in the multiple engine concept in order to make applications more fuel efficient, reduce emissions and enable lower maintenance costs. Volvo Penta engines are ready for future emissions demands since they are prepared to integrate with any aftertreatment installation. Furthermore, Volvo Penta allows a very high backpressure on its engines, which results in a compact catalyst that could replace a standard muffler (in function and size).

New and available in parallel with the start of this year’s expo will be low-spec AUX engines for local-build marine gensets – that is, without an engine control system. These will enable local genset builders to independently build up control systems, reducing the cost of the base package of the AUX engines. Members of the Volvo Penta team will be pleased to explain how this will open up opportunities for genset builders and system integrators worldwide.

Reintjes alternative drive concept

Reintjes, a leading manufacturer of marine gearboxes for main drives with power ratings from 250-30,000kW, will present its innovative hybrid solution technology. The compact system achieves low energy consumption and far lower noise levels, and enables smooth running.

As visitors to the Amsterdam RAI will discover, the RHS technology offers a solution for numerous operating modes, with diesel or electric drives available for selection. Depending on what is required, both types of propulsion can be used within their optimal efficiency curves. In addition, a booster function is planned, which will offer the possibility of combining the diesel and electric drive for higher speeds or higher thrust.

RHS can be used as a PTI so that the necessary energy for slow-speed drive or booster application is provided by a genset or a battery pack on board. Optionally, the system can be used as a PTO. In this mode, the diesel engine drives the electrical machine, working as a generator, and provides electrical power to charge batteries or supply the onboard grid.

To enable easy installation, the combined electric motor and generator are already flanged to the gearbox and supplied with a frequency converter. Part of the Reintjes range, the RHS is suitable for fixed propeller applications and available with electric machines from 60-630kW.

Norwegian Electric Systems wins contracts for Estonian port authority

Norwegian Electric Systems has announced the successful contract signing of new orders with the Estonian port authority worth approximately US$11.65m. NES does most of its business in the offshore support vessel and self propelled jack-up vessel markets, but with a reduction in oil prices, it was important for the company to diversify into other, less vulnerable markets.

Last year, NES sold solutions to military naval vessels, fishing vessels and now, most recently, is set to deliver electrical propulsion solutions to state-of-the-art car ferries. The ferries have been designed by the innovative naval architects and engineers of LMG Marin, and are to be owned and operated by the Port of Tallinn. Previously, NES's only experience in the ferry market was the upgrading of a Norwegian ferry, Olav Dun, two years ago, much to the satisfaction of its owners.

A total of four ferries have been ordered. Two will be built by the Polish yard Remontowa, and two by the Turkish yard Sefine. Both yards are renowned for the quality of the vessels they produce.

“This is a triple first for us in Norwegian Electric Systems. These will be our first new-build car ferries, the first time we have sold to Sefine shipyard and the first time we have ever worked with Port of Tallinn,” said Fridtjof Erichsen, sales manager for Norwegian Electric Systems. “The competition, from Germany and the USA, to supply the electric propulsion systems for these vessels has been fierce, but Norwegian Electric Systems was able to offer the best technical solution along with highly competitive commercial terms. We look forward to working with our new partners in delivering car ferries that will serve the people of Estonia well for many years to come.”

Corvus Energy, BAE HybriDrive and Northern Lights power new hybrid research vessel

Corvus Energy, Northern Lights and BAE systems now power Spirit of the Sound, a floating marine education classroom and research vessel. The vessel, a 19.8m (65ft) catamaran, will operate in Long Island Sound for The Norwalk Aquarium in Connecticut.

The Corvus Energy lithium battery will provide the high-density energy storage for propulsion and house loads. Two 100kW diesel Lugger L1064A generators from Northern Lights will be used to recharge batteries, as well as providing a boost when propulsion demand outpaces battery capacity. BAE Systems provided a new design of hybrid marine propulsion (known as HybriDrive) that allows placement of individual components anywhere in the vessel, providing the best weight and space usage possible. A solar array and wind turbine provide supplementary power for the navigational and scientific equipment.

Combined, the technology will reduce diesel fuel consumption by an estimated 75% or more.

As Bob Kunkel, project manager and design integrator, explained, “The propulsion system does not rely on mechanical connections, only by cabling. This gives a vessel designer flexibility in where the components are located, and allows freedom for weight distribution and space savings measures.”
“We are very pleased Corvus Energy was selected to be part of this new educational vessel and to work with world-class marine partners such as BAE and Northern Lights,” said Corvus Energy CEO Andrew Morden. “We are proud to be part of what we believe to be the world’s most advanced and most environmentally responsible vessel of its type.”

The new vessel will offer both a climate-controlled indoor classroom and an outdoor research space with total capacity of 65, more than doubling that of the aquarium’s current boat. The aquarium expects to double the number of school children who can experience the programming out on Long Island Sound to approximately 10,000 a year. Running quietly on electric power will benefit wildlife and other boaters, as well as enhancing the delivery of educational programmes on board.

Wärtsilä high-tech engines to power environmentally sustainable Baltic Sea ferry

A new fast ro-pax ferry, ordered by the Estonia-based Tallink Grupp for its Tallinn-Helsinki route, will feature Wärtsilä dual-fuel (DF) engines running primarily on liquefied natural gas (LNG). The ship is to be built at the Meyer Turku shipyard in Finland and is scheduled to be in operation from the beginning of 2017. The contract with Wärtsilä was signed in February.

By opting for Wärtsilä’s DF engine technology with LNG used as the main fuel, the ship will comply with the International Maritime Organization’s (IMO) latest sulphur emissions legislation, which came into force in January 2015. The Baltic Sea is designated as a Sulphur Emissions Control Area (SECA). When operating in gas mode, the sulphur oxide (SOx) and particle emissions from the Wärtsilä DF engines are negligible at almost 0%. Furthermore, the nitrogen oxide (NOx) emissions are at least 85% below those specified in the current IMO regulations, and CO2 emissions are some 25% less than those of a conventional marine engine running on diesel fuel.

The full scope of supply includes three 12-cylinder Wärtsilä 50DF and two six-cylinder Wärtsilä 50DF main engines, as well as two Wärtsilä fixed-pitch propellers and propeller shaft lines. The equipment will be delivered to the yard in early 2016.

“The ferry will operate at fairly high speed and to very tight schedules,” said Mika Ojutkangas, general manager, sales, Wärtsilä Ship Power. “It is, therefore, important to the customer that the main engine propulsion is highly efficient and extremely reliable. Wärtsilä’s extensive track record is proof of our ability to meet these criteria. At the same time, we are the leading supplier of gas-fuelled solutions to the marine industry, and this was another reason for being awarded this important contract.”

“The Wärtsilä engines are more energy efficient and thus consume less fuel, and for a next-generation environmentally sustainable ferry that is what we were especially looking for,” said Tarvi-Carlos Tuulik, head of ship management at Tallink Grupp.

The new 212m ferry will have a gross tonnage of 49,000 and will carry 2,800 passengers.

Wärtsilä's 50DF engine can be run on natural gas, light fuel oil (LFO) or heavy fuel oil (HFO), and can smoothly switch between fuels while operating. It is designed to provide the same output regardless of the fuel. Both the gas admission and pilot fuel injection are electronically controlled. The engine functions are controlled by an advanced automation system that allows optimal running conditions to be set, independent of the ambient conditions or fuel type. The 50DF engine is designed to allow use of Wärtsilä's remote diagnosis and dynamic maintenance planning solutions. These features offer owners a significant reduction in operating costs by applying predictive maintenance principles and by optimising engine performance. One of the reasons for the strong success of this particular engine over the alternatives is its superior propulsion efficiency. The clear environmental advantages that operating on gas allows are another factor in the success of the technology.

Feadship launches the world’s first hybrid superyacht

Feadship has launched the 83.5m Savannah, the first superyacht to combine a single diesel engine, three gensets, batteries, propeller, azimuthing thruster and a streamlined hull shape. Offering fuel economies of 30%, the pioneering electromechanical propulsion platform marries Feadship’s past experience and forward-thinking approach with a pure custom creation. Further innovation comes in the form of a floating superstructure, an underwater lounge, the open aft deck areas and much more besides.

Inspired by the 2010 Feadship concept, Breathe, Savannah is a demonstration of cost-effective, cleaner propulsion that can be achieved within an entirely bespoke superyacht. Savannah has a dynamic hull shape with a very fine entry, uses one efficient medium-speed Wärtsilä main engine instead of two higher-rev diesel motors, a single central propeller shaft installation on the centreline and three gensets.

Redundancy is ensured by fitting a large contra-rotating and azimuthing stern thruster just aft of the main propeller. The design of the aft ship allows for a propeller that is 40% larger than normal. Combined with the power supplied by the thruster, the load on the propeller is only half that of a conventional twin-screw yacht. This results in a higher efficiency and fewer vibrations. In addition, the large stern thruster also ensures excellent manoeuvrability in marinas.

The complete design package offers major benefits in terms of fuel saving, and consists of five modes: manoeuvring, diesel-electrical, range, high speed and boost. Feadship claims that this guarantees a high level of reliability and a better engine load than any other superyacht afloat today. “It is not the individual technologies used on Savannah that are new in the yachting world – it is the way they have been combined,” says the owner’s project manager, Ted McCumber. “Feadship has leveraged on all the options available in the marine industry today to bring this hugely innovative system to completion.

“The possibility to choose between diesel, diesel-electric or fully electric is truly exceptional. Moreover, Savannah is the first yacht in the world to be running with an Azipull and a variable-pitch propeller. Only Feadship engineering and the rich experience of this yard could have successfully concluded a project of such scope and vision.”

Feadship director, Henk de Vries, is also keen to highlight the vessel’s fuel-saving capabilities. “As the first ever hybrid superyacht, Savannah offers incredible flexibility in operations and loading of the power plant. The result is fuel savings of some 30% compared with the best boats that we have launched to date.

“The way in which one gigantic propeller has been installed in front, with another electrically powered prop in its slipstream, has also never been applied on a yacht. A similar system has been used on board passenger ships in Japan, but that is an industrial solution, without the attention to comfort required on a Feadship. To achieve this on a superyacht entailed an exceptional degree of cooperation with Wärtsilä and all the other equipment manufacturers.
“Another major innovation is the batteries, which were suggested by the owner. These provide extra speed at the top end, allow proper loading of the generators at any speed, and facilitate super-quiet cruising at slow speeds without any engines turning. We have installed Li-ion batteries with no less than one million watts.

“More than a thousand people have been involved with the creation of Savannah since the contract was signed at the end of 2011. And the tremendous final result once again shows how Feadship is never afraid to venture into uncharted waters.”

Havyard increases holding in Norwegian Electric Systems

The Havyard Group now has a 50.5% ownership interest in the technology company Norwegian Electric Systems.

Before the acquisition, Havyard Group owned 37.9 % of Norwegian Electric Systems. By purchasing shares from companies belonging to Jan Berg and Frithjof Hustig, the group is now the company’s majority shareholder. After the acquisition, Berg’s and Hustig’s companies will own 32.28% and 6% (respectively) of Norwegian Electric Systems. The remaining shares in the company are owned by other key personnel. At his own request, Jan Berg will start in a new role in the company, while Tor Leif Mongstad will take over as the new CEO.

Havyard Group’s strategy is to develop and deliver ship technology through expertise in, and control of, the critical links in the value chain for the design and construction of advanced vessels. Increasingly, these ships have diesel-electric or hybrid propulsion systems, which are a critical and strongly integrated element in the overall ship design. This was why Havyard was involved in the start-up of Norwegian Electric Systems, and why the group has now acquired the majority of the shares in the company.

Geir Johan Bakke, president and CEO of Havyard Group, believes that it was natural for the Group to now play a more active role in Norwegian Electric Systems, in order to further develop the company. “Norwegian Electric Systems is an agenda-setter as regards the development of new, advanced ship designs based on diesel-electric or hybrid propulsion systems,” he explains. “Collaboration with the supplier of such products is decisive if we are to develop the best ships and deliver the agreed quality to our demanding customers – at the right time and on budget. Our main motivation for increasing our holding in Norwegian Electric Systems is that we want to contribute to developing even better products for our customers, whether they buy a system from Norwegian Electric Systems or a ship design or new-build from Havyard. This will result in value added for Havyard, Norwegian Electric Systems and our customers in the form of even better and more competitive products.”

Tor Leif Mongstad will take over from Jan Berg as CEO of Norwegian Electric Systems. At his own request, Jan Berg will become head of business development in the company. Norwegian Electric Systems will continue as an independent company with responsibility for its own product development, sales and production. However, there will be increased focus on realising synergies as a result of the collaboration with Havyard – for example, in relation to procurements and production.

“Synergies can be achieved in particular from the collaboration with Havyard Power & Systems, which also has products and expertise in electronics and electric systems,” says Mongstad. “One example is switchboard production. Another is Havyard Power & Systems’ expertise in electric designs and ship engineering, which will provide valuable input to Norwegian Electric Systems’ product development.

“In addition to the potential inherent in the existing diesel-electric systems, we believe that Norwegian Electric Systems’ newly developed hybrid battery diesel-electric propulsion system, Quest, will have a big market and substantial environmental benefits. It will mean big savings on fuel and will significantly reduce emissions to air.

“Until now, I have been a customer of Norwegian Electric Systems and, as such, have reaped the benefits of the excellent products they have delivered for Havyard’s new-builds. I am now looking forward to starting this job and contributing to continued positive development together with Norwegian Electric Systems’ highly capable organisation.”

Jan Berg, founder and former principal owner of Norwegian Electric Systems, is one of the pioneers in his field. He started as an apprentice electrician in 1964, and worked both as a ship’s electrician and on the sale and development of electric products and systems for several companies before becoming involved in founding Scandinavian Electric in 1984.

As he developed the company, Berg focused on overall expertise in electric systems and on delivering electronic services to the maritime industry, which became the company’s main market. Early on, the company started to deliver motors, generators and frequency converters to equipment suppliers, shipyards and shipping companies.

Berg believes that close collaboration and long-standing relations with good subcontractors were critical for the companies he has developed. “Close proximity to the experts in the products and systems we deliver is another critical success factor. Where other companies have had to rely on subcontractors and external consultants, we have focused on having this expertise in-house. It is easy to solve service-related challenges or problems with developing a new product when you can find the answer by popping in on a colleague in the office next door.”

Now that Mongstad is taking over as CEO of Norwegian Electric Systems, Berg will concentrate on developing selected markets. He will also be responsible for sales to some of the company’s big existing customers, and contribute to the company’s general business development. “I have known Tor Leif since the early 1990s, and we have cooperated on several levels for many years. In recent years, Tor Leif has also been a member of the board of Norwegian Electric Systems. We know each other well and complement each other, so I think we will make a great team that can take the company a step further. It will probably be a bit of a challenge not to be in charge any more, but I’m sure we will manage.”

Elkon wins propulsion system contract for two Seaspan
hybrid ferries

Elkon, a subsidiary of Imtech Marine, has been awarded a contract from Sedef Shipyard in Tuzla, Istanbul, for the delivery of the electrical equipment, propulsion system and services for two Canadian Seaspan hybrid ferries.

The two 148.9m, dual-fuelled (diesel and liquefied natural gas) ferries are propelled by a hybrid-electrical propulsion system and can accommodate up to 59 trailers. The state-of-the-art ferries will replace aging vessels and significantly reduce greenhouse gas emissions, say the partners, while ensuring the highest level of efficiency, performance and reliability.

For the new Seaspan hybrid vessels, Elkon will make a considerable contribution to reducing emissions, mainly by being responsible for the design, specification, production and installation of the complete electrical system, including the hybrid-electrical propulsion unit, battery pack and automation system. Discussing the win, Ali Can Yurdakul, Elkon marketing manager, said, “These vessels are complex and very innovative with the additional hybrid battery system.

Elkon is proud to have been awarded this contract from Sedef – a long-term partner of our company – to assist the yard in completing this innovative and sustainable project. Of course, we will make sure that everything is on time, of good quality and within budget.

“We have some 50 highly specialised electrical and mechanical engineers, and next to that, Elkon has more than 350 employees active in execution and installation of projects. We have delivered more than 500 vessels over the last 30 years.”

Elkon and Sedef Shipyard are based in the heart of the shipbuilding industry near Istanbul, and have worked with each other for more than two decades. Both Elkon and its parent company, Imtech Marine, have considerable industry experience in working on hybrid vessels.

Imtech Marine has been active in the Canadian market for many years and has offices in Vancouver, Halifax and Quebec. Most recently, Imtech Marine also supplied a hybrid propulsion system for the diesel-electric hybrid ferries operated by CMAL on the west coast of Scotland.

Seaspan Ferries Corporation has over 100 years of marine transportation experience operating to and from Vancouver Island. Construction on the ferries is scheduled to start in early 2015, and both are expected to be in operation by late 2016. Elkon’s dedicated project team will start installation on the two new vessels mid-2016.

Corvus launches air-cooled rack system for Li-ion
battery modules

Corvus Energy has unveiled its latest product innovation, the Cube air-cooled rack system, which has been designed for the company's popular AT6500 lithium-ion battery modules.

The standard AT6500 module is the world’s first lithium-ion battery to be specifically engineered for use in hybrid drive systems of commercial vessels. The innovative battery pack has helped define the hybrid movement in marine markets, having been deployed in more than 90% of large commercial marine systems worldwide. Heat buildup in these modules is exchanged with ambient air passively through a heat-sink.

The Cube air-cooled rack system provides a built-in duct and plenum system that facilitates circulation of cooled air around the modules. The system is highly configurable, with the ducting being able to be tuned to keep all modules in an array at the same temperature, regardless of where in the array they are located. Corvus says that not only does the Cube system prevent temperature gradients across large battery arrays, it also provides a meaningful improvement in power-handling capability.

The standard AT6500 system is the only one of its type to carry type approvals from DNV GL, Lloyd’s Register and American Bureau of Shipping.

Battery-powered cable ferry completes 4,000 trips

Scandinavia’s first lithium-ion-powered electric car ferry has successfully completed more than 4,000 trips. Sailing daily between Mjånes and Hisarøy in Norway for more than a year, the KF Hisarøy electric cable ferry was launched in September, 2013 with a new propulsion power system. This consists of a complete rechargeable battery system from Electrovaya in cooperation with Solund Verft, HAFS Elektro & Rør and Electrovaya’s subsidiary, Miljobil Grenland in Norway. The owner of the vessel is Wergeland Halsvik and Gulen Skyssbåtservice is the operator.

The 100kWh prototype battery system is based on Electrovaya’s SuperPolymer 2.0 technology and can help save up to approximately 180,750 liters of fuel consumption over the vessel’s expected lifetime. Overall, the KF Hisarøy has the potential to save about 500 tonnes of emissions: 480 tonnes of CO2, nine tonnes of particulate matter and volatile organic compounds, two tonnes of carbon monoxide and two tonnes of other emissions. The lithium-ion battery also eliminates fuel exhaust including the usual carcinogens from diesel exhaust.

The cable ferry is operating approximately 10 round trips per day between the mainland and the Hisarøy Island, a round-trip distance of about 1.6km. It is driven by two winches on board and the onboard lithium-ion battery system is recharged on the mainland between the round trips and overnight. KF Hisarøy is built to carry 49 passengers and six cars.

“Wergeland Halsvik is very pleased with the ferry and the battery system delivered from the yard and its cooperating partners,” said Hans Wergeland, owner of KF Hisarøy. “As this market grows, and the demand for environmentally friendly, zero carbon footprint energy solutions increases, this system is well suited to further opportunities in the marine sector.”

Innovative hybrid passenger ferries approach completion

The completion of two new vessels, the M/V Berlin and M/V Copenhagen, at Danish shipyard Fayard, remains on schedule, according to operator Scandlines. The two new passenger ferries are expected to be put into operation on the Rostock-Gedser route in the second half of 2015.

The ferries, which will replace the M/V Kronprins Frederik and M/V Prins Joachim, will both feature Scandlines’ innovative hybrid propulsion system combined with a scrubber that cleans the engine exhaust streams of pollutants such as sulphur and particulate matter and reduces emissions by at least 90%.

Scandlines says M/V Berlin and M/V Copenhagen are “tailor-made for the route and will offer ample space as each ferry will have a capacity of 1,300 passengers and 480 cars or 96 trucks compared to 977 passengers and 210 cars or 42 trucks today”.

During the last few months, engineers have worked to reduce the weight of both vessels, and a new bridge was installed on the M/V Berlin. As opposed to the original design, the bridge has been moved to the top deck to give navigators with better views. Navigation equipment has also been sent to the supplier for an update to avoid installing outdated equipment.

It is anticipated that as many as 500 people will be involved in the completion of both vessels, which includes the installation of closed-loop scrubbers, the replacement of cabling, installation of HVAC systems and new interior lightweight materials on decks 7 and 8.

Liquid-cooled energy storage system development

A high-power liquid-cooled energy storage system (ESS) is being used in the shore-based recharging stations of the new-build Nordled Ampere ferry.

The AT6500 ESS by Corvus Energy has been installed inside Siemens’ power management system and contains 224 AT6500 modules with a total capacity of 1.46MWh. Unlike other power management systems, the Siemens system allows for a significant portion of the battery capacity to reside on shore. According to the Corvus, the battery’s low impedance and advanced active cooling system, combined with Siemens high-power charging equipment, facilitates rapid battery-to-battery power transmission. The vessel’s onboard battery will reportedly be substantially replenished even during short turnarounds.

Sean Puchalski, vice president of business development at Corvus Energy, said, “The ESS is split into four parts: two vessel-¬mounted systems (one each end of the ferry) and two shore power stations (one each end of the route). This facilitates rapid recharging of the vessel-mounted batteries at either end of the voyage and reduces the need for expensive upgrades to electrical grid infrastructure at the ports.”

Nordled’s new ferry is expected to enter operation on the Lavik to Oppedal crossing on the Norwegian west coast in early 2015, and will produce no local emissions. Ampere has capacity for 120 cars and up to 360 passengers.

Ice breakers to receive electric systems worth US$4.7m

Norwegian Electric Systems (NES), a leading integrator of diesel-electric and hybrid-electric propulsion systems, has signed a new contract worth US$4.7m to supply the complete electric system for two new ice breakers (type HD843 ICE).

The vessel, which will be built at Havyard Shipyard in Leirvik, Norway, will feature a DNV ice class Icebreaker Ice 10 and will be winterised cold (-30ºC), which means the ship can break through ice more than 1m thick and can avoid icing.

NES previously signed for the delivery of its propulsion system to another icebreaker, hull no. 122, owned by Femco, which will be ready for handover in Q4 2015.

The company celebrated its fifth anniversary this summer, and has, during this period, commissioned 30 vessels worldwide with NES equipment installed. Another major new development is QUEST (Quadro Energy Storage Technology), which contributes to fuel savings, NOx and C02 reductions and places less demand on the running of multiple diesel gensets. NES says a number of products are currently in the R&D pipeline and will be launched in the first half of 2015.

Norwegian hybrid ferry MF Finnøy completes three-month trial

Corvus Energy has announced the completion of a three-month trial of the hybrid ferry MF Finnøy. The refit vessel used a 960V, 260kWh energy storage system (ESS) consisting of 40 Corvus Energy AT6500 advanced lithium polymer batteries. The ESS was integrated with the existing drive systems provided by Siemens AS, and powered by two 650kW diesel generators.

MF Finnøy, built in 1999, has a capacity of 350 passengers and 110 cars. It runs on the 20-minute crossing between Lauvvik and Oanes in Norway and spends about 10 minutes in harbour on each side, loading and off loading. The conversion of the diesel electric ferry to a battery hybrid design delivered reduced greenhouse gas emissions, improved maintenance costs and reduced fuel consumption.With the three-month trial complete, the owner will now assess the viability of completing a permanent conversion and installation, to realise ongoing cost reductions.

“This trial proves the Corvus energy storage product is an effective solution for modernisation of existing vessels, extending their usable lifespan and reducing costs for the operators,” said Sean Puchalski, vice president, Business Development of Corvus Energy.

First ever installation of integrated Aquarius MAS with marine solar power

Eco Marine Power (EMP) has installed an Aquarius Management & Automation System (MAS) integrated with a marine solar panel array on board the Blue Star Delos.

The Aquarius MAS, an alarm-handling, performance-monitoring and datalogging platform, has been installed as part of a joint renewable energy project with Blue Star Ferries. The approximately 2kW trial solar array on board the vessel is now in operation and providing a source of renewable energy for the ship.

The Aquarius MAS installed on Delos includes a KEI 3240 CPU/AGU, LCD touchscreen monitor, input/output link system (ILS), associated hubs, power supplies and charge controllers plus an FC-38 battery pack from Furukawa Battery, and flexible marine-grade solar panels from Solbian Energie Alternative.

In addition to monitoring the performance of the solar panel array, the Aquarius MAS will report on the status of the battery pack; when the ship is at sea, it will also display in real time the fuel consumption of the main engines and calculate emissions (CO2, NOx and SOx). The installation was carried out by Blue Star Ferries and EMP’s technical partner in Greece, Triad.
Greg Atkinson, chief technology officer at EMP, said: “The Aquarius MAS and solar power installation on Delos demonstrates that solar power on ships combined with a flexible datalogging and alarm-handling platform makes sense. Not only will the system allow Blue Star Ferries to monitor their fuel use and emissions, but it will also help the company reduce fuel consumption by tapping into the limitless and clean power provided by the sun.”

Cummins launches QSK50 optimised for variable-speed diesel electric applications

Cummins has announced the availability of its QSK50 marine engine for variable-speed diesel electric (VSDE) marine applications. The 50-litre platform has been used in traditional fixed-speed diesel electric applications, as well as traditional propulsion and power generation, since its launch in 2006.

Although Cummins says its existing ratings can be utilised in VSDE applications, the new 2,183hp at 1,800rpm QSK50 rating was optimised specifically for variable-speed applications and is designed to provide maximum fuel efficiency at all operating points. Further efficiency gains can be achieved via the power management system, according to the company. .

“Cummins will play a critical role in the advancement of this more efficient technology, supplying engines to system integrators for packaging into complete variable-speed diesel electric packages,” said Waldemar Marchetti, director of strategic growth – offshore. “We will continue to expand our product line, skills and capabilities, working with partner suppliers to design customised packages utilising the latest technology.”
Over the coming months, Cummins will also offer additional ratings optimised for VSDE, while at launch all ratings will meet IMO Tier II emissions at the ISO E2 and E3 test cycles.

Efficient MAN engine for new Alaskan workboat

The Ava Jane has become the first workboat to feature the highly efficient MAN EPA Tier 3 commercially rated propulsion engine.

MAN says it has specially adapted the internal elements of its entire new engine range without increasing consumption at full load, all in advance of the introduction of new, highly challenging exhaust regulations. The workboat, which will spend most of its life operating in the harsh waters of Bristol Bay in Alaska, is capable of travelling at more than 25 knots, with the straight six-cylinder able to produce 537kW (730hp).

Tough EPA Tier 3 regulations call for an additional 20% reduction in nitrous oxides (NOx) and a further 40% reduction in particle emissions compared with EPA Tier 2.

MAN offers a broad range of high-speed four-stroke diesel engines for use in commercial marine applications. For heavy-duty vessels – with unlimited operating hours and a full-load operation share of up to 100% – including for tugs and other workboats, MAN offers an output range from 190 to 735kW (258 to 1,000hp).

For medium-duty applications (up to 4,000 hours per year at a full-load operation share of up to 50%), including for ferries, fishing boats and passenger boats, the output range runs from 294 to 1,029kW (400 to 1,400hp). For light-duty applications (up to 1,000 hours per year at a full-load operation share of up to 20%), including for escorts, ambulances and police boats, MAN's engine range offers efficient six-, eight- and 12-cylinder engines providing 537 to 1,324kW (730 to 1,800hp).

MHI delivers super eco hybrid ship

Mitsubishi Heavy Industries (MHI) has delivered its super eco cargo-passenger ship, the Tachibana-Maru, to Tokai Kisen at the company’s Shimonoseki Shipyard and Machinery Works.

The groundbreaking vessel features a high-efficiency hybrid propulsion system that MHI says achieves outstanding energy savings, environmental load reduction and enhanced passenger comfort and safety.

Measuring 118m in length, 17m in width, and 8.95m in height, the 5,681 gross tonnage vessel has a service speed of 19 knots per hour and has already begun operations on a route between Tokyo and the Izu Islands.

MHI began construction of the advanced ship in March 2013. Its technical highlight is a high-tech tandem-hybrid contra-rotating propeller (CRP) propulsion system developed in-house by MHI engineers. The system is comprised of single-shaft propulsion propellers driven by low-speed marine diesel engine and electric-drive azimuth propulsion propellers that enable the direction of propulsion power to be freely changed. In comparison with conventional twin-shaft propulsion setups, the new system enables fewer appendages for propulsion systems such as skegs, shaft brackets and rudders. It also reduces water resistance, and improves energy-saving efficiency by allowing the use of only fuel-efficient low-speed diesel power in bays and channels where slower navigation speeds are required. The new propulsion system enables the Tachibana-Maru to achieve 15.6% higher fuel efficiency than the Salvia-Maru, a cargo-passenger ship built by MHI and currently in service at Tokai Kisen. In addition, the use of an electronically controlled fuel-injection system enables the main low-speed marine diesel engine to achieve higher combustion efficiency, thereby ensuring that the Tachibana-Maru emits less carbon dioxide and nitrogen oxides. The ship is also equipped with a system that utilises exhaust gas thermal energy more efficiently.

The propulsion system’s ability to deliver required power using only a single-shaft configuration, with the load shared between a single diesel engine and an electric drive system, ensures higher passenger comfort by reducing both noise and vibration. In addition, the electric-drive azimuth propulsion system can be used as a stern thruster in combination with the bow thruster to enhance safety and swiftness when approaching or departing the pier

Corvus Li-ion modules for new hybrid ferry

Corvus Energy and Spanish shipyard La Naval have announced the award of an energy storage contract for an advanced new hybrid ferry.

The new vessel, named Texelstroom, is being built for Dutch ferry operator TESO and will run between Texel Island and the Holland mainland. Texelstroom represents a new-generation vessel for the transportation of up to 1,750 persons and 350 vehicles. Powered by either low-sulphur (bio) diesel or CNG, the ferry will also have over 700m2 of solar panels to reduce its dependence on fossil fuels. The ferry’s advanced energy management system will utilise 252 Corvus Energy AT6500 48V lithium-ion modules.

The 1.6MWh battery capacity will be used to increase efficiency of the ferry and for backup power. This large battery reserve means that the entire ferry can be run on battery power alone in case of emergency. This energy storage system (ESS) also enables the designers to specify smaller generators, as the batteries can be used to provide short power-up and power-down capabilities. Class approved by Lloyd’s Register, the Corvus Energy system is the only Type Approved ESS for marine vessels in the market today.

“We are very pleased that Corvus’s energy storage system was selected for this innovative and leading-edge vessel,” said Andrew Morden, acting CEO of Corvus Energy. “We are very proud to partner with LaNaval in making the Texelstroom the world’s greenest passenger ferry.”

Cees de Waal, TESO director, added, “TESO’s investment in Texelstroom shows our ongoing commitment to increasing efficiency in our systems. These efficiencies will not only benefit the company and customers in terms of reduced costs, but also the environment in terms of reduced emissions.”

The adaptable and modular Corvus ESS allows vessel system integrators and designers an alternative source of energy to redesign systems and reduce system complexity and costs.

Shipyard De Hoop reveals first hybrid FSVs

Shipyard De Hoop has launched the first two of seven all-new hybrid-propelled Fast Supply Vessels (FSVs), which have been specifically designed to efficiently transport deck cargo and passengers to offshore oil fields.

The two new vessels – code numbered 455 and 456 – offer reduced emissions and improved consumption thanks to their state-of-the-art hybrid diesel-electric propulsion. At low speed and during manoeuvring, the FSVs operate by having only one diesel engine in use that drives a generator, which produces power for the two electric motors, driving the propeller shafts through the gearboxes and a bow thruster. Shipyard De Hoop says such a drivetrain arrangement offers crucial fuel savings at low speeds at up to 12 knots and when in dynamic positioning mode. At high speeds, both diesel engines of the FSVs will engage with their respective gearboxes to provide up to 4,700kW to the two propellers.

The DP2 class vessels have been designed to provide day accommodation for a total of 100 seated passengers and cargo capacity of 150 tons deck mounted. The 100m2 area that makes up the passenger accommodation includes comfortable seating, a self-service buffet enclosure and ample luggage storage. On-demand music and video entertainment facilities have also been installed.

The multi-chine all-steel hull of the FSVs has been optimised for fuel-efficient operation in both transit and DP mode. The lightweight steel construction has been designed and built according to Lloyd’s High Speed Craft regs; weight;saving measures have been realised through the use of high-tensile steel in combination with advanced construction techniques.

Now that the first two Shipyard De Hoop FSVs have been launched, the plan is for the remaining five vessels to be delivered across the rest of this year. The steel hulls of YN453, YN455, YN457 and YN459 are being built at the CSR facility in Rotterdam, and will be outfitted at De Hoop’s base in Lobith. The remaining hulls are being produced at Groningen Shipyards in Waterhuizen and will be outfitted at De Hoop’s Foxhol facility.

Carbon-neutral hybrid mega-yacht launched at the expo

Introduced at Electric & Hybrid Marine World Expo 2014, the SWATH Electra Glide Limousine Tender is said to be the world’s first carbon-neutral solar hybrid mega-yacht tender that, according to its makers, combines the environmental benefits of solar electric sustainability with the no sea sickness comfort of an anti-roll SWATH vessel.

Powered by twin 300hp Regen electric outboards, the Tender’s maximum speed is 45 knots. Even so, its makers say this state-of-the-art high-performance tender is far greener, more ergonomic and virtually silent. And unlike power from IC combustion engines, it is extremely efficient throughout its entire speed range. At 8 knots the 50kWh lithium-polymer batteries give the Tender a zero-carbon range of up to 40 nautical miles. The 20kW/day solar panels produce up to 7MW annually, which at 16 knots is enough energy to travel more than 1,000 carbon-neutral nautical miles.

In typical ship-to-shore commuting, the Tender’s Solbian solar array generates all the energy needed. If more power is required, a choice of diesel gensets up to 85kW extends the Tender’s range and boosts hotel services while recharging the batteries in under an hour.

Built by Nedship, other innovative features are the luxury of its 2m standing height and the convenience of its fully equipped galley and bar, which expands the utilisation of the Tender to day-trip expeditions, allowing for beaching in remote areas due to the SWATH twin-hull design.

Richard Sauter, head of design, commented, “The SWATH Electra Glide Tender takes us to an era of responsible luxury yachting, where zero-carbon solar power is a standard requirement and anti-roll, full standing spaciousness is taken for granted.”

LaNaval wins hybrid electric ferry project

LaNaval Shipyard in Spain has signed a groundbreaking contract to design a new hybrid-electric ferry for Dutch company Royal NV Texels Eigen Stoomboot Onderneming (TESO).

The ferry, which will be named Texelstroom, represents a new-generation vessel for the transportation of up to 1,750 people and some 350 vehicles. Just as importantly, the pioneering ferry, which measures 135m in length and 28m in width, will be powered by either diesel or natural gas in combination with electric battery technology that forms an integral part of the application’s advanced energy management. Furthermore, Texelstroom will boast over 7,000m2 of solar panels.

The new ferry will be used in continuous operation between the port of Den Helder, in the north of the Netherlands, and the island of Texel. LaNaval says it fought off fierce competition to win the Texelstroom contract, with TESO choosing the Spanish shipyard thanks to its technical and commercial leadership. The two-year project is said to represent a multi-million euro win as well as some 600,000 working/development hours.

New marine battery modules revealed

Saft has launched a new Seanergy range of lithium-ion battery modules that have been developed to offer the proven safety, performance and reliability advantages of Li-ion Super-Iron Phosphate (SLFP) chemistry in a fully integrated solution designed specifically for civil marine propulsion installations.

The new range includes a variety of energy and power modules that offer the flexibility and adaptability to create highly efficient, cost-effective battery systems to power full-electric and hybrid electric applications for a wide variety of vessels including work boats, ferries, offshore support, cruise liners and cargo ships.

“Silent, clean and cost-effective operations are now key priorities for the marine transportation industry,” says Didier Jouffroy, Saft’s marine products and applications manager. “That’s why Saft has responded by developing the Seanergy range that offers the advantages of our advanced SLFP battery chemistry in a safe, reliable and flexible modular package.”

Saft says that the trend for electric propulsion is being driven by the needs of the civil marine industry to demonstrate that it is sustainable and energy efficient. This means it has to adapt quickly to meet ever-tighter environmental regulations that aim to reduce emissions and noise nuisance while increasing efficiency. As a result, new concepts in ship architecture are now incorporating advanced battery technology for pure electric propulsion and hybrid systems, where the batteries work in conjunction with diesel generators, or possibly gas turbines, and electric motors.

The key advantages of Saft SLFP cell technology for marine applications are its increased safety, its lightweight and compact size, high efficiency, long calendar and cycling life, fast-charging capability and high power output – both continuous and in pulses – and the ability to deliver high voltages up to 1,000V.

Siemens drive technology for new Hyundai vessel

Siemens Drive Technologies has announced that it is supplying an integrated high-tech diesel-electric drive and power-generation propulsion solution for a multipurpose offshore construction vessel (MOCV) that's being built by Hyundai Heavy Industries for Toisa at the largest shipyard in the world in Ulsan, South Korea.

The MOCV, which will eventually be managed by Sealion Shipping, a global shipping and support services company, will be used for a variety of duties including underwater installations to a maximum depth of 3,500m. The integrated Siship propulsion solutions from Siemens will help improve the reliability and flexibility of the vessel as well as reduce its fuel consumption and overall running costs.

The partners say that with the new vessel, Toisa will set new standards in terms of flexibility and capacity. The vessel is designed for a wide range of duties, including ultra-deepwater installations and constructions for the oil and gas industry, the laying of undersea pipes and cables or the control of remotely operated vehicles. Consequently, the demands on flexibility, efficiency and reliability of the vessel are very high. For this reason, says Siemens, it is providing integrated solutions for marine propulsion (Siship Drive LV) as well as for onboard power generation (Siship Power MV).

Siship Drive LV is a diesel-electric drive solution featuring components that are optimally tailored to the design of the vessel. The azimuth thrusters, the retractable thrusters and the bow thruster are powered by five 3.4 megawatt and two 2.5 megawatt motors combined with seven marine-type Siship frequency converters. The converters are specially designed for harsh operating conditions in terms of the temperatures, vibrations and humidity levels prevalent in offshore vessels. The optimum interaction of motors and converters contributes to a rapid reaction capability of the different drives, thus increasing the flexibility of the vessel and enabling precise manoeuvring. Thanks to the integrated drive system, a high level of motor performance and a high degree of efficiency is achieved.

Six diesel generators feed the onboard power supply system, each with an output of four megawatts. As the generator output is continuously adapted to the actual energy demand, a significant reduction in fuel consumption is achieved, especially considering the fluctuating operation profile of a multipurpose offshore construction vessel. The power management system, which is also supplied by Siemens, ensures a stable generation of electricity so that the necessary power can be made available everywhere and any time.

Wärtsilä confirms arctic PSV order

A new platform supply vessel (PSV) to be built specifically for operating in harsh arctic conditions is to be designed and powered by Wärtsilä. The order marks the first confirmed contract for Wärtsilä Ship Design’s new series of arctic PSVs.

As part of the deal, Wärtsilä will supply an integrated package that includes machinery, and the electrical and automation systems, including the patented Wärtsilä Low Loss Concept (LLC). This highly redundant diesel-electric system provides additional reliability for continuous operation in various failure modes.

The ship will be built at the Kleven yard in Norway on behalf of REM Offshore AS, the Norwegian fleet owner. The vessel is scheduled for delivery in the first half of 2015, and will feature the latest developments of Wärtsilä Ship Design’s proven VS 485 design.

“Wärtsilä’s unique position as a total solutions provider to the marine sector has again been endorsed with this contract calling for both the ship design, and a comprehensive power solution. This significant order takes us a step further towards our goal of becoming a leading player in the market for ice class vessels,” said Magnus Miemois, VP of solutions at Wärtsilä Ship Power.

Åge Remøy, CEO of Rem Offshore AS, added, “There is increasing oil company exploration being carried out in northern Russia, Greenland, the Barents Sea and other arctic waters. This requires vessels specifically designed for these conditions, and Wärtsilä has shown that it can efficiently meet such needs.”

The ship will be strengthened and equipped for arctic operations, with the hull and propulsion fitted to comply with DNV ice class ICE 1B. This verifies that the vessel has sufficient strength, power and equipment to operate in arctic conditions. Furthermore, the vessel will be readied for cold-climate conditions according to the DNV class Winterized Basic guidelines. This notation includes requirements for maintaining safety and vessel operability in ice, under icing conditions, and at low temperatures. The new Wärtsilä design broadens the company’s very popular 485 range with an arctic option, combining the efficiency and high level of redundancy with arctic operational capability.

The Wärtsilä LLC will enable the vessel to fulfil the highest possible Environmental Regularity Number (ERN) of 99.99.99. The ERN rating represents the capability of a vessel to maintain its position and normal operations under certain weather conditions. As such, Wärtsilä is the first supplier capable of providing such a high ERN.

Corvus technology for new Scandlines hybrid ferries

Corvus Energy, an exhibitor at Electric & Hybrid Marine World Expo, has been selected by Scandlines as the energy storage system (ESS) provider for company’s next three hybrid ferries.

Based on the success of Scandline’s first hybrid, the MF Prinsesse Benedikte, the next hybrid applications will again use a 2.7MWh ESS technology consisting of Corvus Energy AT6500 advanced lithium polymer batteries integrated with Siemens drive systems. The newly refitted hybrid ferries will deliver significantly reduced greenhouse gas emissions, improved maintenance costs and optimised engine performance, resulting in greatly decreased operating expenses.

The ferries M/V Deutschland, M/V Schleswig-Holstein and M/V Prins Richard, in operation on the Puttgarden and Rødby route (alongside the MF Prinsesse Benedikte), will comprise the largest fleet of hybrid vessels in operation today. A vital economic link between Denmark and Germany, the ferries are in service 24 hours a day, 365 days a year and have sailings every 30 minutes from each side.

The system was put to the test on a recent crossing with several senior Scandlines executives, Denmark government officials, Lloyd’s Register engineers and Corvus Energy executive staff on board. With no notice, the diesel generators were purposely taken offline. Instantly sensing the loss of power from the generators, the Corvus Energy ESS seamlessly filled in the gap, and provided full power for all the ship’s systems without even a flicker in the lights.

“The 2.7MWh of modules are the most reliable and safe battery in the world, designed to operate both house and driveline systems,” stated Corvus Energy’s CEO Brent Perry. “Siemens, the integrator, is using this partnership opportunity as a template to develop a seamless, customer-based solution for current and future ferry fleets around the world. We are honoured to again provide energy storage for such a high-profile and important fleet, with esteemed partners like Siemens and Scandlines.”

Fassmer and AG Ems to build Heligoland ferry
