NES, the Norwegian battery systems provider, has been selected by Fjord1 to provide hybrid system integration for three of its 125-capacity car ferries.
The Moldefjord-series ferries will be converted during the second half of 2020, with battery packs, integrated electrical and automation systems delivered by NES. Ferry berths will also be equipped with a land-based charging system to serve the updated vessels. Originally designed by LMG Marin of Bergen and built by Remontowa in Poland, the ferries will have their combustion engines replaced to become fully zero-emission.
“After several previous deliveries to our ferries, we have gained good experience with NES,” says Nils Kristian Berge, project director at Fjord1.
The world’s leading international event for electric and hybrid marine technology has revealed its preliminary program for the 2020 conference. Electric & Hybrid Marine World Expo and Conference 2020 will be held June 23-25 at the Amsterdam RAI, the Netherlands, and will once again provide an exceptional opportunity to see industry leaders share their innovations, knowledge and insights through a comprehensive and diverse range of conferences and panel discussions. Highlights include:
Dr Makhlouf Benatmane, Marine navy solutions leader, GE Power Conversion will discuss the HMS Queen Elizabeth aircraft carrier (QNLZ), the first aircraft carrier in the world to utilize integrated full electric power and propulsion system IFEP.
A study by UMAS and the Energy Transitions Commission for the Getting to Zero Coalition has concluded that the collective investment required to meet the global target of halving shipping emissions between 2030 and 2050 is between US$1tn and US$1.4tn. The figure equates to a required investment of US$50bn to US$70bn annually over 20 years.
“We need to understand the scale of the challenge to solve it,” says Johannah Christensen, managing director at the Global Maritime Forum, a partner of the Getting to Zero Coalition. “Shipping’s shift to zero carbon energy sources calls for significant infrastructure investments.
Torqeedo, the German electric and hybrid drive manufacturer, has supplied a battery-electric system to the Swedish Sea Rescue Society.
The Rescue Mercedes Eliasson Sanne is the first vessel in the fleet to have parallel diesel and electric motors, allowing it to operate for up to 90 minutes on electric power alone at a speed of 6kts. Dual Torqeedo Deep Blue 50kW electric motors are powered by two 10kWh Deep Blue lithium-ion batteries, combining with the primary twin-650 horsepower Scania diesel units.
“We use the electric mode when entering and leaving port through Sweden’s environmentally sensitive waterways,” said Lars Samuelsson, head of the Maritime Department.
Praxis Automation Technology, the Dutch marine technology firm, has joined forces with Arksen to develop hybrid propulsion and vessel management systems for its explorer yachts.
The companies are working on the systems engineering of the Arksen 85, with the first vessel due to enter production early this year, and will feature a full hybrid propulsion package supplied by Praxis. The predicted range of the vessel will 7,000 nautical miles on a single tank of fuel, and will be supported by solar charging to offer silent operation.
“When deciding upon the powering and propulsion for the Arksen range of vessels, it was vitally important that we found not only the most suitable equipment package, but the right partner to work with on the development of this most crucial of vessel systems,” says Jim Mair, Arksen’s technical director.
Dutch ESS company EST-Floattech will provide a 1.6MWh energy supply system for the Norwegian trawler Nordbas, operated by NordnesGruppen. Following a retrofitting at the Kleven shipyard in Norway, the Nordbas will feature a battery solution based on EST’s GO1050 air-cooled system, allowing the vessel to operate diesel-free for hours and be charged via renewable sources.
“Due to our high energy density and modular design, EST-Floattech has been able to design this large ESS solution into a very limited battery room,” said general manager Jannik Stanger of EST-Floattech. “It is inspiring to work with companies that integrate both well-established and new technology and focus so much on the reuse of materials for reduced environmental footprint.”
DNV-GL certified, the system will be delivered complete with a specified exhaust system and battery control system for maximum safety during operation.
DNV GL, the industry risk management provider, has delivered a report making recommendations for increased battery safety on board electrified sea vessels.
Produced in collaboration with marine authorities, battery manufacturers, system integrators, shipyards and shipowners, as well as suppliers of fire extinguisher systems, the report has taken input from stakeholders in the USA, Denmark and Norway, and examines the risk of explosions and fire, as well as looking at extinguishing systems.
Research conducted for the report shows how fire behaves when it is enclosed in a battery compartment, the gases that are released in such an event, and how effective different fire extinguishing systems are in tackling such fires.
The latest hybrid service operation vessel for Bernhard Schulte, the maritime solutions company, has been floated out ahead of sea trials beginning in March.
The Yno 315 is the third offshore wind vessel built by Ulstein for Bernhard Schulte, with this latest vessel benefiting from a new energy management system. Developed especially for this application, the system manages the energy flow between the vessel’s switchboard and the batteries, and is able to manage peak shaving and spinning reserve for maximum efficiency. During lab tests the system demonstrated that the vessel could be operated on a single diesel engine during dynamic positioning operations.
