What happened

A wind farm in Norway was shut down after a blade broke off a Siemens Gamesa 4.X turbine at the project, according to a report dated 12 April 2024. The headline says the farm was shut down again, but the available text does not name the site, the operator or any earlier incident. Injuries, fire and further damage were not reported in the available text.

Contributing factors

Not reported in the available text.

Lessons learned

  1. A blade detachment on a Siemens Gamesa 4.X turbine requires immediate shutdown and an exclusion zone while the turbine and nearby machines are checked.
  2. A second shutdown at the same farm should prompt review of the turbine model and blade history even before the cause is known.
