At the Nor-Shipping trade fair today, DNV signed a classification contract for two new Commissioning Service Operation Vessels(CSOVs), ordered by the Norwegian pure play offshore wind operator Edda Wind. The vessels will be built at Colombo Dockyard in Sri Lanka and are designed for service operations during the commissioning and operation of offshore wind farms and are prepared for hydrogen operations. They are scheduled to be delivered under the Norwegian Flag in January 2024 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 the demand for renewable energy soars over the coming decade. The new additions to the Edda Wind fleet will function as mother ships for wind turbine technicians as they perform commissioning and maintenance work on wind turbines, with accommodations for up to 97 technicians and 23 marine crew. The planned hydrogen fuel system will be based on the Liquid Organic Hydrogen Carrier(LOHC) design by Hydrogenious LOHC Maritime AS and prepares the vessels for future zero-emission operations.
The two CSOVs will be built to the Salt 0425 design and measure 89.3 meters. They are in principal sister vessels to a DNV-classed newbuild which is currently in construction at the Spanish shipyard Astilleros Gondán. Some of the key features include anti-heeling and roll reduction systems to provide good working conditions onboard and a motion compensated gangway system with an adjustable pedestal to ensure safe and optimal connections to the turbines, even in harsh weather conditions.
