Damen Shipyards Group has launched the second commissioning service operation vessel (CSOV) 9020 for Ta San Shang Marine Co., Ltd. (TSSM), a joint venture between Japan’s Mitsui O.S.K. Lines, Ltd. (MOL) and Taiwan’s Ta Tong Marine Co., Ltd. The vessel, named TSS Challenger, is under construction at Damen’s Ha Long yard in Vietnam and is scheduled for delivery in early 2027. It will join
its sister ship, TSS Cruiser, in supporting offshore wind farm construction and maintenance in Taiwanese waters. The CSOV 9020 design incorporates features for future methanol operation, including green methanol, and benefits from an optimized hull that reduces fuel consumption. Its hybrid diesel-electric propulsion system contributes to lower emissions compared to conventional vessels. Damen highlighted that the vessel’s capabilities have been adapted from experience in the European offshore wind sector to meet the needs of the rapidly developing Asian market. Thomas Röwekamp, Regional Sales Director Asia-Pacific at Damen, emphasized the vessels’ role in supporting TSSM and its clients in advancing a sustainable regional energy sector. The launch marks a key milestone in Damen’s delivery of environmentally conscious offshore support vessels tailored for the Asian offshore wind industry.
