According to an Odal spokesman, no one was injured in the incident at the Odal wind energy park. The 22-tonne rotor blade that crashed was part of a Siemens Gamesa 5.0-145 turbine, which belongs to the 4.X platform of the Spanish Siemens Energy subsidiary Gamesa, the spokesman said on Thursday.

Gamesa has been struggling with quality problems in the onshore wind turbine business for years, and the 4.X platform is also affected. The Spanish company caused the parent company billions in losses. Siemens Gamesa did not initially comment on the matter.

Connection still unclear

The spokesman said he could not yet say anything about the cause of the incident. It is therefore also unclear whether the crash of the rotor blade is related to the problems mentioned by Gamesa. Odal was closed pending the completion of the investigation. The operator had already stated last month that 15 of the 34 wind turbines were not in operation due to cracks in the rotor blades. The cracks are related to a production error.
