Bernhard Schulte Offshore (BSO) continues to grow its modern offshore wind fleet with the addition of Windea Clarke. Delivered from Ulstein Verft on 2 July 2026, the vessel marks another milestone in BSO’s fleet development programme.
Windea Clarke is the fourth CSOV (Commissioning Service Operation Vessel) delivered to BSO from Ulstein Verft within the past year, and the seventh offshore wind service vessel of Ulstein’s design in their fleet overall. Together, these vessels form a core part of BSO’s strategy to provide high-quality, future-ready offshore service capacity.
Matthias Müller, Managing Director Bernhard Schulte Offshore, said:
“With Windea Clarkewe are completing a strategically important series of vessels that strengthens our ability to support offshore projects with reliable tonnage while significantly reducing the environmental footprint. It enables us to deliver efficient and scalable services across construction, commissioning and maintenance phases to the global offshore energy industry.”
With Windea Clarke, BSO continues to invest in CSOVs purpose-built for safe, efficient and sustainable offshore operations. Their vessels have become key enablers for offshore wind operations worldwide, supporting both construction and long-term operations and maintenance (O&M) activities.
All four vessels delivered to BSO over the past year feature Ulstein’s TWIN X-STERN® solution, ensuring excellent manoeuvrability, reduced motions, and improved operational efficiency in demanding offshore conditions. Combined with hybrid battery propulsion and a design prepared for future methanol fuel, the series of vessels is optimised for low-emission operations.
The vessel is named after the American electrical engineer and academic Edith Clarke, continuing BSO’s tradition of honouring leading scientists. Sister vessels in the series include Windea Curie, Windea Clausius, and Windea Carnot.
