Vard Electro has announced an order from Siem Offshore that will see the company deliver its largest battery package to date. The batteries will be used to retrofit one of the Norwegian company’s vessels as it upgrades its fleet to run on hybrid power to reduce fuel costs and lower emissions.
The supply package for the Siem Offshore subsea construction vessel will consist of a Vard Electro SeaQ Energy Storage System (ESS), two battery packs and a DC link. Installation is scheduled for early 2022 ahead of the ship carrying out work in the wind sector.
Following the installation, the vessel will be able to maneuver in harbors and other restricted areas in a fully electric mode, resulting in zero emissions running and an estimated 20% fuel saving.
Cleantech company Cavotec has won orders from two of the world’s largest container shipping lines for its shore power connection systems. The orders are reportedly worth more than €6.5m (US$7.5m).
Booked in the third quarter of 2021, the orders are for Cavotec’s prefabricated PowerFit shore power connection modules, which will be retrofitted to existing container vessels. These systems will enable the vessels to safely and efficiently connect to shoreside electrical power and will be installed on both sides of the ships to allow for further electrical connections. The delivery of the equipment is scheduled over the next two years.
Exmar and Lattice have signed an agreement for the joint development of a new type of CO2 carrier vessel.
To aid in the decarbonization of shipping, the sector is seeking to utilize carbon capture utilization and storage (CCUS). To make CCUS projects achievable and sustainable, CO2 needs to be transported in an economical way, on a large scale.
The agreement signed between the companies is for the design of a 40,500m3 capacity CO2 carrier vessel, capable of also transporting LPG and ammonia. With the initial Panamax beam vessel concept measuring 195m-long, the ship can be optimized to meet a variety of transportation needs in a cost-effective manner.
Singapore-based shipbuilder Strategic Marine has announced an order for six Strat Cat 27 (SC27) crew transfer vessels for Sam Pan Marine, also based in Singapore, which has the option to expand the order for a further six vessels.
Built in conjunction with design partner BMT, the SC27 has been designed and developed to be environmentally and operationally flexible. The crew transfer vessel has the option to be fitted with a hybrid propulsion system to reduce the boat’s carbon footprint and cut noise and vibration levels. This will reduce the number of hours that the main engines run, resulting in less maintenance and lower emission levels.
Japan-based Yanmar Power Technology (YPT) claims to have carried out the world’s first 70MPa high-pressure hydrogen refueling of a ship.
The demonstration test boat was equipped with a hydrogen fuel cell system and the 70MPa high-pressure refueling was carried out in cooperation with the Toyota Tsusho Corporation. For the test, a specially licensed high-pressure facility was leveraged, along with a newly developed prototype long hydrogen refueling hose.
By utilizing high-pressure hydrogen refueling, the test vessel achieved a cruising time that was three times longer than when a traditional refueling process was used.
Yanmar will use the results of the test to further the market deployment of hydrogen fuel cell systems.
The latest stage of the Scottish-led HySeas III project has seen renderings completed of a proposed hydrogen fuel cell-powered ferry. The project is aiming for the vessel to become Europe’s first sea-going ferry to use the clean propulsion solution.
The proposed ferry is double-ended and has the capacity to carry 120 passengers and 16 cars or, alternatively, two trucks. Designed to store energy from renewable sources, the vessel will serve routes between Kirkwall and Shapinsay in Orkney, where wind power is used to generate hydrogen fuel. The ferry will also be capable of operating to and from other ports where hydrogen becomes available in the future.
A new fast crew supply (FCS) vessel, named the FCS 7011, will be fitted with a Danfoss Editron electric drivetrain.
Selected by designer Damen Shipyards as the propulsion system provider, Danfoss will supply the 74m-long ship with a hybrid-electric marine system consisting of DC distribution boards running around 700V DC, four shaft generators and an Editron load and control system.
In addition, the FCS vessel will benefit from propulsion from four main engines that, through a gearbox, will drive the Hamilton HT900 waterjets and the Danfoss Editron shaft generators. This will improve fuel consumption and passenger comfort due to lower levels of noise and vibration.
Developer of deep-water offshore wind projects Mayflower Wind has signed an agreement with Gladding-Hearn Shipbuilding/Duclos Corporation of Somerset, Massachusetts, for the specification, design and manufacture of a hybrid diesel-electric crew transfer vessel (CTV).
A host of technologies will be applied to the CTV including lithium-ion battery energy storage to create a hybrid vessel capable of full electrification in the future. This will result in fuel savings and the reduction of emissions when carrying out maritime operations.
“Mayflower Wind aims to develop the most innovative, fuel-efficient CTV built in the USA,” commented Michael Brown, CEO, Mayflower Wind.
