A front-row seat to the TWIN X-STERN® series: Onboard a typical CSOV, the ship's hospital is stocked with seasickness tablets and dry biscuits for technicians unaccustomed to offshore conditions. On Windea Carnot, demand for seasickness remedies is nearly zero. Instead, the three-flavour ice cream machine has become one of the most popular features.
Bernhard Schulte Offshore (BSO) continues to grow its modern offshore wind fleet with the addition of Windea Clarke, further strengthening its position in the global energy market. Delivered from Ulstein Verft on 2 July 2026, the vessel marks another milestone in BSO’s ambitious fleet development programme.
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.
Why vessel operability matters more than ever for reducing LCOE; Vessel uptime has become a critical enabler of project performance.
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.
