Bernhard Schulte Offshore takes delivery of CSOV Windea Carnot

Bernhard Schulte Offshore (BSO) has taken delivery of a new commissioning service operation vessel (CSOV), Windea Carnot, expanding its fleet supporting offshore energy operations.

The vessel was built by Ulstein Verft in Norway for an institutional investor and was formally handed over to BSO upon completion. The ship was christened on 6 March 2026.

Windea Carnot is the third of a series of sister vessels delivered from Ulstein to BSO since mid-2025, following Windea Curie and Windea Clausius. With the addition of the new vessel, BSO’s fleet now includes six specialised ships serving the offshore energy sector.

Matthias Müller, Managing Director at Bernhard Schulte Offshore, said:

“The offshore market offers promising prospects. Therefore, we are pleased to have added ‘Windea Carnot’ to our portfolio. The Ulstein design, characterised by reliability, flexibility and innovative features, is very well received by the offshore industry.”

The CSOV features Ulstein’s TWIN X-STERN configuration, a design intended to improve manoeuvrability, reduce vessel motion and enhance fuel efficiency during offshore operations. The vessel also incorporates hybrid battery propulsion and is prepared for future conversion to methanol fuel.

The design allows the ship to support both operations and maintenance (O&M) activities as well as construction work in offshore wind farms and other offshore energy installations.

Windea Carnot is configured to accommodate up to 90 offshore personnel in single cabins. The vessel includes a centrally positioned, height-adjustable walk-to-work gangway with an elevator tower to enable safe transfer of personnel and cargo between the vessel and offshore structures.

Additional equipment includes a helideck capable of handling helicopters with a maximum take-off weight of 8.6 tonnes and a 3D motion-compensated crane with a lifting capacity of up to five tonnes for offshore lifting operations.

The vessel also incorporates a height-adjustable boat-landing system to enable step-free transfer between the CSOV and crew transfer vessels operating within offshore wind farms.

The vessel is named after Nicolas Léonard Sadi Carnot, a scientist known for his contributions to thermodynamics. The naming follows the theme used for its sister vessels, which are named after prominent scientists.
