Damen Shipyards Group has launched the second in a series of two Commissioning Service Operations Vessels (CSOV) 9020 for Ta San Shang Marine (TSSM), a joint venture between Mitsui OSK Lines of Japan and Ta Tong Marine of Taiwan.
The vessels will support construction and maintenance activities at offshore wind farms in Taiwanese waters. When delivered in early 2027, the CSOV 9020, to be named TSS Challenger, will join the Damen-built TSS Cruiser, in the company’s fleet. Damen is constructing the vessel in Ha Long, Vietnam.
Damen’s CSOV 9020 is designed in line with the stringent requirements of the offshore energy sectors. The vessel’s hull form ensures high sea-keeping and stability, providing comfort for the up to 120 personnel on board. The optimised hull design results in lower fuel consumption. This, combined with the CSOV 9020’s hybrid diesel-electric propulsion arrangement, offers a significant reduction in emissions. To ensure the vessel’s continued relevance in the years ahead, the CSOV 9020 is further prepared for future operation on (green) methanol.
Thomas Röwekamp, Damen Regional Sales Director Asia Pacific, said: “We are pleased to have reached this latest milestone in the construction of these two vessels for TSSM. The CSOV 9020 draws on years of experience in the European offshore wind industry. The capabilities of the vessel have been tailored and fine-tuned to support the rapid development of the Asian market. As such, these vessels are well positioned to support TSSM – and its clients – in developing a sustainable regional energy sector in the coming years.”
