EA wind turbine manufactured by Siemens Energy subsidiary Gamesa has lost a 72-meter-long rotor blade in Norway. According to an Odal Vind 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.
“As is usual in such cases, we started the safety protocol and stopped the turbines in the wind farm; no one was injured,” said a spokesman for Siemens Energy. “We now have to calmly investigate the cause; we are in contact with the customer.” He did not comment on details of the system and possible consequences.
The group had withdrawn its onshore types 4.X and 5.X from the market after quality defects. In March, Siemens Energy said it wanted to put the revised versions on sale as quickly as possible. The company will determine when that will be the case.
It is still too early to say what the cause is, said the Odal Vind spokesman. He declined to comment on whether the incident was related to previous quality problems. Odal Vind said last month that it had stopped 15 of the wind farm's 34 turbines due to damage to the blades related to production. Odal has now been closed pending the completion of the investigation.
