The turbine installation campaign for the Butendiek offshore wind farm in the North Sea west of Sylt commenced with the dedicated installation vessel Bold Tern. As part of the project’s construction timeline, Bold Tern sailed from the installation harbour to the Butendiek site carrying eight complete turbine sets per trip. Offshore, the vessel installed each Siemens wind turbine in a five-step sequence: lifting and securing the tower, followed by installation of the nacelle and then each of the three rotor blades. This phase marked the start of systematic offshore wind turbine installation for the 80-turbine, 288 MW Butendiek project.
