Ulstein Verft launched first of Olympic CSOV


On 6th April, the CSOV Olympic Boreas was launched from the dock hall at Ulstein Verft, Norway. The vessel is based on the novel TWIN X-STERN solution, a '4-wheel-drive' solution for the seas. 

The Olympic Boreas is yard number 318 and the first of two sister vessels for Olympic. As construction Service Operation Vessels (CSOVs), they assist in offshore energy construction projects and service assignments.

Representatives from the shipowner and shipyard attended the tow-out from the dock hall.

"We are delighted to witness the launch of the CSOV Olympic Boreas in its true colours. Ulstein's exceptional building quality in the construction process is impressive. We look forward to taking delivery of this state-of-the-art CSOV vessel, equipped with cutting-edge technology that enables sustainable operations, upon its completion this summer," says Frode Andreassen, VP Commercial at Olympic.

Project status

"The general outfitting work, which consists of accommodation work, electrical installations, piping, and mechanical installations, to name a few, is well underway. The external paintwork was completed while the vessel was located inside the controlled environment of our dock hall. Also, the commissioning stage of the project has started," comments project manager Helge Torvik at Ulstein Verft. 

About the vessels

The contract between Olympic and Ulstein was signed in 2022 and includes the construction of two CSOVs at Ulstein Verft. The hulls are built by the Crist yard in Poland. The vessels are powered by diesel-electric propulsion with variable speed and large battery energy storage systems. Ulstein Power & Control has been contracted to deliver an extended power and automation package, including a large battery supply. 

The vessels are based on the ULSTEIN SX222 design from Ulstein Design & Solutions AS. They have a length of 89.6m and a beam of 19.2m and accommodate 126 people in 91 cabins, all with daylight.

The hull shape and hybrid propulsion system will ensure high operational performances and seakeeping and substantially reduced environmental footprint.
