Siemens Gamesa has signed a 10-year agreement with Fred. Olsen Windcarrier for offshore wind O&M support using Bold Tern or Brave Tern. The contract starts in Q1 2028 and covers turbine platforms of up to 15 MW while extending cooperation already seen on Thor and Gennaker.

From 2028, Fred. Olsen Windcarrier will deploy either Bold Tern or Brave Tern to support offshore wind operations and maintenance work for Siemens Gamesa turbines rated up to 15 MW. The agreement runs for a firm 10 years and includes additional option periods.

The new contract adds a long-term service role to vessels already working on Siemens Gamesa projects. Brave Tern is installing 72 SG 14-236 DD turbines at Denmark’s 1.1 GW Thor offshore wind farm and is also booked to install 63 turbines of the same model at Germany’s Gennaker project from 2028.

The deal is expected to start in the first quarter of 2028, according to Bonheur ASA, the parent company of Fred. Olsen Windcarrier. The company said the agreement was concluded on negotiated market terms and conditions.

The fleet’s readiness for this work follows earlier upgrade activity. In 2020, Fred. Olsen Windcarrier launched a programme covering Brave Tern, Bold Tern and Blue Tern so the vessels could handle wind turbines of up to 15 MW. In 2023, the company also placed a further upgrade contract with Navantia for Brave Tern.
