Ulstein has held a keel-laying ceremony for the second of the two Construction Service Operation Vessels (CSOV) ordered by Olympic Subsea ASA at the Crist yard in Poland.

The keel for Olympic Subsea’s first CSOV was laid on 31 January.

The two vessels are designed for the offshore wind industry and are based on the newly developed TWIN X-STERN hull design from Ulstein Design & Solutions AS.

The TWIN X-STERN, with main propellers fore and aft, reduces the energy consumption to a new level when positioned at the wind turbines, Ulstein said.

While the two vessels are being constructed at the hull yard, the project management, planning and follow-up, purchasing, and engineering works are underway at Ulstein.

The first hull is expected to arrive at Ulstein Verft in Norway in the fourth quarter of this year for final outfitting.

The CSOVs are based on the ULSTEIN SX222 design. They have hybrid battery propulsion and are prepared for methanol fuel to enable zero-emission operations.

The vessels 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.

”As a shipowner in the Norwegian maritime cluster, it has been important for us to invest in the Norwegian maritime cluster,” CEO of Olympic Group, Stig Remøy, said.

”With a Norwegian shipyard, ship designers, equipment suppliers and Vartdal Invest as a co-investor, this is a project with strong local ownership. For us, it will be crucial that the vessels are delivered on time and at the right quality, and this is what Ulstein Verft is known for.”
