Acta Marine has taken delivery of Acta Gemini, the third vessel in a series of four ULSTEIN SX216 Construction Service Operation Vessels (CSOVs) featuring the ULSTEIN TWIN X-STERN® design.
On 11 March 2026, Ulstein Verft, Norway, delivered the Windea Carnot, a Commissioning Service Operation Vessel (CSOV). The vessel was built on behalf of an institutional investor and has now been handed over to its new owner, Bernhard Schulte Offshore (BSO).
Ulstein Verft's yard number 322, the CSOV Genesis Sea, is about to conclude a successful sea trial, a major milestone in the newbuild project.
At Ulstein Verft, the new year began with launching, lifting operations and docking of two offshore wind newbuilds.
The hull for yard number 323 arrived at Ulstein Verft on 6 December 2025. This marks another milestone in the construction of our next-generation offshore wind service vessel, which is the tenth TWIN X-STERN CSOV since 2022. The vessel is based on Ulstein’s proven SX222 design platform.
On 15 November 2025, Yard number 322 was successfully towed and positioned inside the dock hall at Ulstein Verft. The project is progressing according to plan, and key activities are now underway.
At Ampelmann’s Walk-to-Work Conference in Rotterdam on 4 November 2025, Henrik Høidal, system architect at Ulstein Design & Solutions AS, delivered a presentation that sparked lively discussions about the future of offshore wind logistics. The topic was the SX250 vessel, a concept challenging today’s thinking on size and operational capability.
The total number of walk-to-work (w2w) vessel designs and redesigns by Ulstein now counts 22, of which 16 are currently in operation. On average, these vessels perform repair and maintenance on more than 5,000 turbines every year! That makes a stunning 95,000+ gangway connections!
On Friday 15 August 2025, the hull for a new offshore wind service vessel of the CSOV type arrived at Ulstein Verft. This marks a new step in the process towards the completion of this state-of-the-art vessel, which has been developed to support energy-efficient offshore wind operations with high performance.
Ulstein Verft has signed a contract with Olympic to retrofit the Olympic Notos for operations supporting unmanned installations on the Norwegian Continental Shelf. This project will provide extensive work for Ulstein.
26 June 2025 – Bernhard Schulte Offshore (BSO) has taken delivery of the state-of-the-art, commissioning service operation vessel (CSOV) WINDEA Curie, yard number 320 from Ulstein Verft.
Olympic's latest CSOV, the 'Olympic Notos', has been operational for six months since her delivery, and the feedback is outstanding.
In February 2025, Ulstein introduced the innovative SX250 design, a vessel specifically engineered to excel in wave heights up to 2 metres Hs. This strategic design choice aligns perfectly with real-world operational data, revealing that 94.2% of walk-to-work (w2w) operations occur in conditions with wave heights below 2 metres.
On 11 March 2025, the hull of yard number (Yno) 321 for BS Offshore arrived at Ulstein Verft. This marks the beginning of a new phase in the shipbuilding process. The vessel is designed by Ulstein Design & Solutions AS for ‘walk-to-work’ (W2W) operations, where personnel walks via a motion-compensated gangway from the ship to a wind turbine.
BS Offshore and Ulstein Verft has passed a significant milestone with the launch of the Yno 320, a state-of-the-art Commissioning Service Operation Vessel (CSOV).
