Danish developer Ørsted reported that at the Anholt offshore wind farm in Denmark, a three-bladed rotor separated from the nacelle of one of offshore wind turbines and fell into the sea. No one was injured.

The developer is asking the relevant authorities to establish “no sail zones” at all offshore wind farms where the 3.6 MW – 4 MW Siemens Gamesa wind turbine is used. In addition to Anholt, offshore wind farms with “no sail zones” include West of Duddon Sands, Lincs, Gunfleet Sands, Burbo Bank as well as Walney 1 and 2, all in the UK, Borkum Riffgrund 1 in Germany, and Avedøre Holme in Denmark.

The Anholt offshore wind farm was commissioned in 2013 and consists of 111 Siemens-Gamesa wind turbines with a capacity of 3.6 MW.

The developer says in a release that they are investigating the cause of the incident. So far, the investigation has not identified a systemic cause of the problem. The wind farm is operating normally with proper safety protocols in place. The developer assures that consumers will not be affected by the outage.
