Germany’s first offshore wind farm project
Located 45 km off the coast of Borkum Island in the North Sea, alpha ventus is Germany’s first offshore wind farm project, reaching an average water depth of 30 m.
By end 2009, we successfully installed and commissioned six AD 5-116. Since then, these turbines have demonstrated their efficiency, achieving up to 135 GWh annually. We also provided offshore installation, service and maintenance services. In 2014, our initial five-year maintenance contract was renewed by DOTI.
