Multiple Hours | DNV to Class Two Hydrogen Ready Commissioning Service Operating Vessels for Edda Wind

The classification society DNV signed a contract on Wednesday April 6 to classify two new Commissioning Service Operation Vessels (CSOV), ordered by the Norwegian offshore wind operator Edda Wind, during the Nor-Shipping show.

The vessels to be built at the Colombo Shipyard in Sri Lanka are designed for service operations during the commissioning and operation of offshore wind farms, and are ready to use hydrogen as bunker fuel.

The planned hydrogen bunker fuel system will be based on the Liquid Organic Hydrogen Hydrogen Carrier (LOHC) design by Hydrogenious LOHC Maritime AS and will prepare ships for future zero-emissions operations.

They should be delivered under the Norwegian flag in January and July 2024.

Advanced CSOVs that offer both next-generation technology and comfortable accommodation are an important part of the value chain in a booming offshore wind segment that is expected to grow as demand for renewable energy soars globally. over the next decade, says DNV.

The new additions to Edda Wind’s fleet will function as mother ships for wind turbine technicians when carrying out commissioning and maintenance work on wind turbines, with accommodation for up to 97 technicians and 23 crew members.

Both CSOVs will be built to the Salt 0425 design and will measure 89.3 meters. They are mainly sister ships of a DNV-classified new build, which is currently under construction at the Spanish shipyard Astilleros Gondán.

Some of the key features include anti-listing and roll reduction systems to provide good working conditions on board and a motion-compensated gangway system with an adjustable pedestal to ensure safe and optimal connections to the turbines, even in harsh conditions. harsh weather conditions.

Håkon Vevang, commercial director of Edda Wind said: “The ordering of these purpose-built CSOVs will further strengthen Edda Wind’s leadership position in offshore wind, and we are very pleased to have DNV as a classification partner on this journey”,

“Considerable growth is expected in the offshore wind market over the coming decades, and this decision is a clear signal of Edda Wind’s ambition to be one of the world’s leading suppliers in this segment and to our commitment to ensuring our new builds are environmentally responsible.”

Thimira S Godakumbura, COO of Colombo Dockyard PLC said: “We are very pleased that Edda Wind has entrusted Colombo Dockyard PLC with the construction of these advanced vessels, and we look forward to working with Edda Wind as a client and DNV as a classification partner.”

“We are proud to have secured a place in these emerging markets and aim to strengthen our position in the future. This exciting project is certainly a milestone.

Tuva Flagstad-Andersen, Regional Director, Northern Europe Region at DNV, said: “We at DNV are very pleased to have been chosen as the preferred classification partner for these new builds and look forward to working closely with all partners.”

“CSOVs are among the most technically advanced vessels, with high demands on safety, maneuverability, digitization and comfort. I am convinced that our experience in the offshore sector will be very useful to us in order to ensure a successful delivery.
