Borkum Riffgrund 1 Offshore Wind Farm

06 Apr 2022: A  rotor including three blades has separated from the nacelle of one of the offshore wind turbines at the Anholt offshore wind farm and fallen into the sea. No one has been injured. The relevant authorities have been notified about the incident. Orsted are investigating the incident and suggest relevant authorities to establish ‘no-sail zones’ at all Orsted offshore wind farms that use the same turbine as at Anholt, namely a Siemens-Gamesa 3.6 MW - 4 MW wind turbine. So far, the investigation has not pointed to a systemic cause of the issue. The assets continue to operate as normal with the relevant safety protocols, and customers in the relevant markets will not be affected.  Besides Anholt, the offshore wind farms with ‘no-sail zones’ are: West of Duddon Sands, Lincs, Gunfleet Sands, Burbo Bank and Walney 1 & 2, all in the UK, Borkum Riffgrund 1 in Germany, and Avedøre Holme in Denmark.
