Two 44-metre blades have broken on a Vestas V90 3MW turbine commissioned at a Danish wind farm in December.
The blades came off “approximately a third of the distance from the tip end” on Sunday at the site close to the town of Sæby in Northern Jutland, Vestas said.
The manufacturer added that “no injuries occurred as a result” and three other V90 3MW turbines at the wind farm are “operating normally”.
“The turbine has been shut down and our service technicians are present at the site. An investigation into the cause of the incident is underway,” a spokesman for Vestas said in a statement.
“Until the investigation is completed, it will not be possible to determine the root cause of the incident. Wind speeds at the time of the incident were not high.”
Vestas is “in dialogue with the owner of the turbine”, which is under service, to replace the blades.
The company has sold more than 2700 V90 turbines (pictured) worldwide.
