Denmark´s Semco Maritime has won a 10-year offshore service contract with Siemens Gamesa for the offshore windfarm Butendiek, starting in January 2014.

The deal covers operations and maintenance on the offshore windfarm Butendiek located in the North Sea around 32 kilometres from the Island of Sylt near the German-Danish border.

Project operations will mainly take place from Havneby at the Danish Island Rømø.

The windfarm has been operational since 2015 and comprises 80 Siemens 3.6 MW wind turbines for a total capacity of 288 MW supplying around 370,000 households with renewable energy.

Semco Maritime is responsible for balance-of-plant service workstreams, including scheduled and unscheduled maintenance and inspections above water on the offshore substation, and its foundation as well as the 80 wind turbine generator foundations.

Jacob Øbo Sørensen, senior vice president, renewables, Semco Maritime, said: “We are excited to leverage our offshore experience and partner with Siemens Gamesa on our first 10-year service contract for offshore wind operations and maintenance at Butendiek. This is another important milestone in our efforts to boost Semco Maritime’s service business in the renewables space, and we are looking forward to cooperating closely with the client and all involved parties.”
