Damen Shipyards, Windcat, and CMB.TECH have jointly launched the first of a series of Commissioning Service Operation Vessels (CSOV) in Ha Long, Vietnam. This vessel, part of Windcat's Elevation Series, is a groundbreaking development in offshore wind farm maintenance and support. Designed through a collaborative effort, the CSOV integrates CMB.TECH's dual fuel hydrogen technology, marking a significant step towards environmental sustainability in the marine industry. The partnership initially planned for two vessels but expanded to a total of six due to increased demand. With a length of 87 meters, the vessel can host 120 crew members for extended stays at offshore locations. Damen aims for high efficiency by eliminating the need for a backup diesel generator and ensuring optimal power usage. By incorporating a hybrid-electric propulsion system and advanced thruster configuration, the vessel promises substantial reductions in fuel consumption and emissions. The innovative features are expected to enhance dynamic positioning during operations, further emphasizing the vessel's eco-friendly design. This initiative reflects a positive industry shift towards green technology and collaboration for a more sustainable future.
