Giant wind turbine collapses for an unknown cause

The wind turbine was completely destroyed by the collapse, as a spokesman for RAG MI announced. All that remained was a 40-meter-high stump made of concrete parts. ... The twin system, which is around 450 meters away, was put out of operation for safety reasons immediately after the collapse became known. "It will not be put back into operation until the cause of the accident has been clarified." According to the municipal utilities, the wind turbine was connected to the grid when it collapsed.

Block Island offshore wind farm still down for maintenance and safety inspections

Workers at the Merkur wind farm in the German North Sea found signs of stress fatigue on the support structures of the “helihoist” platforms on some of the project’s GE Haliade turbines. Power generation at the 396-megawatt array was temporarily halted to come up with a solution to the problem, but the wind farm has since come back online. In June, Ørsted said it had put the five-year-old Block Island Wind Farm “on pause as a precautionary safety measure” to see if similar problems had arisen with the platforms at the top of the turbines that equipment and workers can be lowered onto from helicopters.

Broken, burned-out towers pose possible threat to public

“I am not someone whose nerves get on edge very easily, but I didn’t want either myself or my people close to it. What I saw gave me fear,” said Wreath. “I left with many more concerns and questions than I had arrived with.” The 120-megawatt capacity project — located along the Oklahoma-Texas state line between Guymon and Hardesty — went operational in 2012 and contains 60 towers within Oklahoma. About nine towers show signs of catastrophic failure, where portions or entire blades are missing or nacelles at tower tops have burned. Dozens of other towers are locked down, either because of internal damage that can’t be observed without a detailed inspection or because of other problems that could be impacting their operations.
