Dutch shipbuilder Damen has been awarded a contract to construct the sixth commissioning service operation vessel (CSOV) for Windcat, an offshore personnel transfer provider. This project further solidifies the partnership between Damen, Windcat, and CMB.TECH in the development of the 'Elevation Series' of CSOVs. The vessels will be utilized by Windcat to offer in-field technical and maintenance assistance to offshore wind farms for extended periods. Construction of the CSOVs is taking place at Ha Long Shipyard in Vietnam, with the first vessel expected to be completed by early 2026. Noteworthy is the incorporation of dual fuel hydrogen technology in these vessels, a collaboration involving CMB.TECH and drawing on insights from Windcat's hydrogen-powered Crew Transfer Vessel (CTV). Damen's Sales Manager Benelux highlighted the significance of this hydrogen component, emphasizing the transition from new technology to proven sustainability. The culmination of expertise from Windcat, CMB.TECH, and Damen has resulted in the design of an 87-meter-long vessel capable of accommodating 120 individuals. This collective effort showcases a pioneering approach to integrating hydrogen technology in offshore operations.
