One turbine's blades fall off at Ørsted's Danish offshore wind farm

Ørsted A/S (CPH:ORSTED) said today that a rotor with all three blades split from the turbine's nacelle and fell into the sea at its 400-MW Anholt offshore wind farm in Danish waters.

The incident is still being investigated, but so far nothing has pointed to a systemic cause, the Danish offshore wind major said. No injuries were reported.

The affected wind turbine is from the Siemens Gamesa 3.6 MW-4 MW family, one of 111 Siemens Gamesa turbines that make up the Anholt wind farm.

Ørsted said that it is taking extra precautionary measures, and is requesting that the relevant authorities establish “no-sail zones” at all of its offshore wind farms that have the same turbines as the ones installed at Anholt.

A no-sail zone was established at Anholt, but also at West of Duddon Sands, Lincs, Gunfleet Sands, Burbo Bank and Walney 1 & 2 in the UK waters, Borkum Riffgrund 1 in Germany, and Avedøre Holme in Denmark.

“The assets continue to operate as normal with the relevant safety protocols, and customers in the relevant markets will not be affected”, Ørsted said.

The Anholt offshore wind farm was commissioned in 2013.
