Nexra said its service operations vessel Wind Keeper is ready to begin her first project after completing a technical and visual upgrade in Europe.

Following her acquisition last year, Wind Keeper transitioned to Europe and underwent modifications aimed at improving operational capability, alongside a full exterior and interior refurbishment that aligns her onboard offering with the rest of Cadeler’s fleet. The upgrade also covered welfare enhancements, including a new gym and upgraded facilities, with the company noting crew approval of the updated onboard environment.

With a 2,200-tonnes main crane, Wind Keeper is positioned to support both installation and operations and maintenance (O&M) work in the 15 MW turbine segment.

Over the coming months, the vessel will support Vestas and EnBW Generation UK with the installation of 15 MW turbines at the He Dreiht Offshore Wind Farm in the German North Sea. The company said the project is the first commercial-scale installation of the Vestas V236-15.0 MW model.

Wind Keeper was acquired last year and immediately secured a long-term contract with Vestas. Nexra said the vessel serves as a flagship unit within its dedicated service concept, supporting long-term partnerships and full lifecycle services for offshore wind assets, including maintenance, upgrade and optimisation.

He Dreiht is a 960 MW project and is expected to power approximately 1.1 million households once completed.
