Launch of first Olympic CSOV

The first of two construction service operation vessels (CSOVs) for Norway’s Olympic has now been launched at its building yard, Ulstein Verft. The CSOV Olympic Boreas and its sister vessel will be assisting in offshore energy construction projects and service assignments. 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. The hull shape and hybrid propulsion system will ensure high operational performances and seakeeping and substantially reduced environmental footprint, Ulstein said.

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. 

"We are delighted to witness the launch of the CSOV Olympic Boreas in its true colours. The exceptional building quality demonstrated by Ulstein 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," said Frode Andreassen, VP Commercial at Olympic.

"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 whilst the vessel was located inside the controlled environment of our dock hall. Also, the commissioning stage of the project has started," commented project manager Helge Torvik at Ulstein Verft.
