Denmark’s Semco Maritime has won a 10-year service contract from Siemens Gamesa for the 288 MW Butendiek offshore wind farm in the German North Sea.

The work covers operations and maintenance on the wind farm located around 32 km from the Island of Sylt near the German-Danish border. Project operations will mainly take place from Havneby at the Danish Island Rømø, starting in January 2024.

The wind farm has been operational since 2015 and comprises 80 Siemens 3.6 MW wind turbines. Semco Maritime will be responsible for balance-of-plant service workstreams, including maintenance and inspections above water on the offshore substation and its foundation as well as the 80 wind turbine generator foundations.

“This is another important milestone in our efforts to boost Semco Maritime’s service business in the renewables space,” said Jacob Øbo Sørensen, senior vice president of renewables at Semco Maritime.
