German renewable energy developer RWE has formed a long-term partnership with UK shipowner North Star for the charter of two commissioning service operation vessels (CSOVs). The companies have also signed reservation agreements for two new SOVs to be built by Norway’s Vard Group.

The Grampian Eagle CSOV is chartered for at least twelve years to support operations at the 857 MW Triton Knoll offshore wind farm off the British coast.

For a minimum of ten years, the Grampian Kestrel will support maintenance of RWE’s German offshore wind projects near Heligoland Island.

Both vessels were built this year and can use alternative fuels to reduce CO2 emissions. The charter for Germany starts this winter, and for the UK, in summer 2026. RWE may extend both contracts by up to three more years.

Each 87.5-metre CSOV includes a motion-compensated gangway with an elevator, a boat landing system, and accommodation for up to 120 personnel.

Until the North Star vessels are ready, Windward Athens and Windward Paris will be supplied by Windward Offshore until the end of 2026.

“Through this long-term partnership, RWE is taking a strategic step by securing next-generation service operations vessels amid a tight market,” said Thomas Michel, COO of RWE Offshore Wind.

As part of the reservation agreements, two newbuild SOVs are planned to support RWE’s expanding offshore wind fleet from 2028 and 2029.

North Star has chosen the global shipbuilding firm VARD for these projects.

The multi-million-pound four-vessel agreement is expected to ensure employment for up to 200 personnel, including up to 100 new roles over the next decade, according to the UK company.
