Nordseecluster offshore wind project reaches important milestone: first monopile foundation successfully installed off the German coast
28.07.2025
RWE has entered into a long-term partnership with North Star, the UK’s largest shipowner-operator, backed by global private markets firm Partners Group, acting on behalf of its clients. The companies have agreed that RWE will charter two next-generation service operation vessels (SOVs), the Grampian Eagle and the Grampian Kestrel, from North Star - both capable of using alternative low-emission fuels. Full marine services will be delivered by North Star as part of the charters. RWE and North Star have also signed reservation agreements for two newbuild vessels delivered by the Norwegian Vard Group. This partnership will pave the way for the efficient and low-emission operation of RWE’s existing and further growing offshore wind portfolio in Europe.
Thomas Michel, COO of RWE Offshore Wind: “Through this long-term partnership, RWE is taking a strategic step by securing next generation service operations vessels against the backdrop of a tight market. Those service operations vessels are an important enabler for RWE to deliver best-in-class performance across our existing operational fleet, as well as for future projects.”
The specialised vessels provide accommodation for service technicians and can remain at the wind farms for several days. Integrated walk-to-work gangway systems make access to the wind turbines much easier, even in rough seas, while also increasing safety. These vessels are therefore an ideal solution, especially for the maintenance of offshore wind farms that are located further offshore.
Gitte Gard Talmo, CEO of North Star: “This landmark deal is the beginning of a strategic partnership between two industry leaders, built on early engagement, mutual trust and shared ambitions. We are proud to secure agreements for four state-of-the-art vessels and grateful for the trust put in us by RWE. Our focus is delivering world class operational performance, utilising all of North Star’s expertise and capabilities in SOV services.”
The Grampian Eagle is chartered for at least 12 years. This vessel is planned to support the operations and maintenance activities at Triton Knoll offshore wind farm off the British coast. For a minimum of 10 years the Grampian Kestrel will support the maintenance of RWE’s German offshore wind farms, located north of the island of Heligoland. Both vessels were built this year and offer the possibility to use alternative fuels to minimise CO2 emissions.
For Germany, the charter contract starts this winter and for the UK in summer 2026. RWE has the option to extend both contracts by up to additional three years.
Until the North Star vessels Grampian Eagle and Grampian Kestrel are available two state-off-the art vessels will be supplied by Windward Offshore until the end of 2026 - a role-model for cross-industry collaboration.
Furthermore, as part of the reservation agreements RWE has signed with North Star, two newbuild service operation vessels are planned to support the maintenance of RWE’s growing offshore wind fleet from 2028 and 2029 onwards. North Star already has selected the global shipbuilding company VARD to construct these vessels.
Leading global player in offshore wind
RWE is one of the world’s leading companies in offshore wind. The company currently operates 19 offshore wind farms in five countries with a total installed capacity of 6.2 gigawatts (GW) – RWE’s share in these projects amounts to 3.3 GW. Furthermore, RWE currently has four offshore wind projects under construction in four countries: Sofia off the coast of North East England, Thor in Denmark, OranjeWind off the Dutch coast and Nordseecluster north of the island of Juist, Germany. The projects will be completed in the years 2026 to 2028, and will have a combined generation capacity of 4.8 GW, with RWE’s share amounting to 3.1 GW. Further offshore wind projects are under development globally.
