DNV to class Edda Wind CSOVs for hydrogen operations

DNV and Norwegian offshore wind operator Edda Wind have entered into a classification contract for two new commissioning service operation vessels (CSOVs).

The Salt Ship-designed, 89.3-metre-long vessels will be built at Colombo Dockyard in Sri Lanka. Once in service, they will be used for commissioning and operation of offshore wind farms.

The vessels will function as mother ships for technicians as they perform commissioning and maintenance work on wind turbines. Accommodations will be available for 97 technicians and 23 crewmembers on each vessel.

The CSOVs will also be prepared for hydrogen operations. The planned hydrogen fuel system will be based on the liquid organic hydrogen carrier (LOHC) design by Hydrogenious LOHC Maritime.

The vessels are scheduled for delivery in January 2024 and July 2024, respectively.
