On 11 March 2025, the hull of Yard Number (Yno) 321, a state-of-the-art CSOV walk-to-work (W2W) vessel for Bernhard Schulte Offshore (BS Offshore), arrived at Ulstein Verft from CRIST shipyard in Poland. This milestone marks the beginning of a new phase in the shipbuilding process, as the vessel moves into the outfitting and commissioning stage.
Designed by Ulstein Design & Solutions AS, the vessel is tailored for walk-to-work operations, enabling personnel to safely transfer from the ship to offshore wind turbines or other structures using a motion-compensated gangway. This capability is critical for supporting offshore wind farm maintenance, inspection, and repair activities, ensuring safe and efficient operations in challenging offshore environments.
While the hull has been under construction at the CRIST shipyard in Poland, closely monitored by a site team from Ulstein Verft, the designers and engineers at the various Ulstein companies in Norway and Poland have been working on finalising the detailed drawings for the ship. The hull arrival at Ulstein Verft marks a new phase, which includes securing, painting, outfitting, piping, equipment installations, electrical work, and system integration.
The vessel is a sister to Yno 320, launched at Ulstein Verft on 23 February.
“We are pleased to see the journey toward completing the second CSOV is progressing and look forward to the continued progress and collaboration in bringing this vessel, designed with efficiency, safety, and sustainability at its core, to life”, says Matthias Müller, Managing Director Bernhard Schulte Offshore.
Like its predecessor, the newbuild is part of the innovative TWIN X-STERN CSOV series, known for its exceptional operational performance and seakeeping abilities. During the outfitting phase, the vessel will be equipped with advanced technology, including a 3D-compensated crane and a gangway, ensuring safe and efficient personnel and cargo transfer to offshore wind turbine facilities.
The vessel will also have a diesel-electric propulsion system with substantial battery energy storage, significantly reducing the environmental footprint. She is prepared for methanol as a future fuel.
After her delivery in 2025, the vessel will be ready to support the offshore wind sector with modern, high-comfort accommodation for up to 132 crew and clients.
This is Ulstein’s fifth W2W vessel for BS Offshore. All have been designed by Ulstein Design & Solutions AS and constructed at Ulstein Verft. BS Offshore is a pioneering ship owner, and Ulstein is proud to continue the partnership, contributing to the advancement of sustainable maritime solutions.
