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.

Huge Vestas wind turbine collapses in Northern Sweden in rare accident

The cause of the accident is unknown and the company is assembling a team that will investigate at the site, spokesman Anders Riis said on Monday by phone. A lot of snow is expected this week, which may delay the work, he said. No one was injured in the incident. Sweden is turning to the most mature renewable energy source to replace old nuclear reactors.

230 meter high wind turbine collapsed

It was at 9 pm on Saturday evening that the wind turbine gave way and fell to the ground. Pictures taken by Norran show how the tower folded a few meters above the ground and then the turbine housing, tower and blades crashed down. ...It is now Vestas that will carry out an investigation into the accident.

Dundonnell wind farm gets green light to expand, loose bolts blamed for blade fall

Last month, Dundonnell was also hit by a fallen blade at one of its Vestas turbines, which brought production across the wind farm to a halt for a few days as the cause was investigated. Campbell says it is clear that the blade fell because bolts holding it to the hub became loose, but the question of why those bolts became loose is still under investigation.
