Damen Shipyards Group has delivered TSS Cruiser, the first of two Commissioning Service Operations Vessels (CSOVs) 9020 for Ta San Shang Marine Co., Ltd. (TSSM).

The handover took place in Ha Long, Vietnam, after sea trials in Ha Long Bay.

TSSM is a joint venture between Japan’s Mitsui O.S.K. Lines, Ltd. and Taiwan’s Ta Tong Marine Co., Ltd. The offshore wind support vessel will be deployed at Taiwanese wind farms during construction and operational phases.

A naming ceremony was held on 29 April, with senior representatives from both joint venture partners and Damen attending. Patricia Liao, president of Welcome to Taipei International Club, named the CSOV TSS Cruiser.

The 90-metre ship can accommodate up to 120 offshore personnel, with transfers carried out through a motion-compensated gangway. TSS Cruiser features hybrid diesel-electric propulsion and is prepared for conversion to methanol propulsion in the future.

Speaking at the naming ceremony, Hrong-Nain Lin, chairman of TSSM, said: “On behalf of TSSM, I would like to thank the Damen Group. Your professionalism, efficiency, and strong teamwork have made the successful delivery of this vessel possible. Our mission is to support Taiwan’s offshore wind industry and to contribute to a cleaner and more sustainable ocean. TSS Cruiser represents our core values – putting people first and maintaining a strong commitment to safety and quality.”

Bram Langeveld, chief commercial officer of Damen, remarked: “I would like to offer my heartfelt appreciation to TSSM for placing its trust in Damen. You have been a true partner during this project. Your collaborative spirit and unwavering professionalism have been instrumental in bringing this vessel to life. Together, we have turned obstacles into opportunities and challenges into progress.”

Following delivery, TSS Cruiser left Vietnam on 6 May for Taiwan, where its first assignment will be at the Hai Long Offshore Wind Farm, which will use Siemens Gamesa turbines.

The second CSOV 9020 is scheduled for delivery early next year.
