Vessel conversions and re‑mobilisations demand more than drawings and calculations. Recent work on Orient Adventurer, now being prepared for cable-laying operations, demonstrates how critical in-depth knowledge of a vessel’s operational history is to deliver safe, class-approved solutions. Through Ulstein’s aftermarket services, we support complex vessel upgrades with engineering, stability, and weight expertise, including planning and executing inclining tests for conversion and life‑extension projects.

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.

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. 

Aurora Expeditions' Douglas Mawson was officially named in Sydney on 27 November 2025 before embarking on her inaugural trip to Tasmania. This milestone marks history as the first expedition vessel featuring Ulstein’s X-BOW® design to operate in Australian waters. More than a striking visual signature, this pioneering hull shape represents a breakthrough in maritime engineering.

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.

On 13 November 2025, the Nexans Electra cable laying vessel (CLV) was positioned quayside at Ulstein Verft, marking a major milestone in the vessel’s journey towards completion. During its time at Ulstein Verft, the vessel has been in a roofed, controlled environment, ensuring optimal conditions for work environment and precision painting.

The Ålesund-based company Blue Ctrl is making strategic changes to its leadership to strengthen its continued growth and position within the maritime technology sector. On 1 November, Marielle Furnes Mannseth will assume the role of Managing Director of the company.

In October 2025, Edda Freya called at Ulstein Verft for a mobilisation on very short notice. In addition to several minor tasks, the vessel's crane, weighing 350 tonnes, needed to be relocated.

With the delivery of Douglas Mawson on 9 September 2025, the seventh vessel in the Infinity class for SunStone Ships, the proven ULSTEIN CX103 platform continues to demonstrate its strength.
