Danish offshore energy service provider Semco Maritime has been awarded a 10-year balance-of-plant service contract for operations and maintenance at the Butendiek offshore wind farm in the North Sea. The wind farm, operational since 2015, is located approximately 32 kilometers from the Island of Sylt near the German-Danish border and consists of 80 Siemens 3.6 MW wind turbines with a total capacity of 288 MW, supplying renewable energy to around 370,000 households.

The contract, effective from January 1, 2024, has been signed with Siemens Gamesa, which holds the overall contract and is responsible for turbine maintenance and offshore logistics towards OWP Butendiek GmbH & Co. KG. Semco Maritime will manage balance-of-plant service workstreams, including scheduled and unscheduled maintenance, as well as inspections above water on the offshore substation, its foundation, and the 80 wind turbine generator foundations.

Jacob Øbo Sørensen, Senior Vice President, Renewables at Semco Maritime, expressed excitement about leveraging their offshore experience and partnering with Siemens Gamesa on their first 10-year service contract for offshore wind operations and maintenance at Butendiek. The project operations are primarily based in Havneby on the Danish island of Rømø.
