First Steel Cut for Second Olympic CSOV Newbuild

January 5, 2023, by Adnan Memija

Ulstein Verft has held a steel-cutting ceremony for the second Construction Service Operation Vessel (CSOV) that the company is building for the Norway-based shipowner Olympic Subsea ASA.

The vessel, which carries yard number 319, is the second of two offshore wind newbuilds for which the shipowner signed a contract back in July 2022.

In November last year, the steel-cutting ceremony at the hull yard Crist in Poland marked the first milestone for Ulstein Verft on newbuild 318.

The CSOVs are among the first vessels to implement the TWIN X-STERN from Ulstein Design & Solutions, a design where the ship has two sterns and main propeller units in each end which should increase flexibility and operability.

Both vessels are based on the SX222 design and will have a length of 89.6 metres, a beam of 19.2 metres, and will be capable to accommodate 126 people in 91 cabins.

The vessels are powered by diesel-electric propulsion with variable speed in combination with large battery energy storage systems and are prepared for methanol fuel with space available for additional battery capacity for full-electric repowering when the infrastructure for such is available.

Olympic’s CSOVs will feature Ampelmann’s gangways, while the energy storage systems and main switchboards for the vessels will be delivered by Corvus Energy and Acel, respectively.
