Dutch shipbuilder Damen has secured a contract to build the sixth commissioning service operation vessel (CSOV) for Windcat, an offshore personnel transfer provider. This vessel, part of the 'Elevation Series', is aimed at providing in-field technical and maintenance support to offshore wind farms for extended periods. What sets this project apart is the integration of dual fuel hydrogen technology into the vessel, a pioneering move in the industry. Damen, along with partners Windcat and CMB.TECH, is at the forefront of turning this new technology into a proven one. The vessel, currently under construction at Ha Long Shipyard in Vietnam, will be 87 meters long and have a capacity for 120 personnel onboard. The collaborative effort between the three parties involved brings together expertise in offshore crew transfer services, future-proof fleet ownership, and innovative shipbuilding. By drawing on the success of Windcat's hydrogen-powered Crew Transfer Vessel (CTV) and insights from CMB.TECH, the 'Elevation Series' CSOV aims to be a game-changer in sustainable marine technology.
