An early morning fire on April 2nd destroyed the top portion of the seven-year-old turbine. The fire burned itself out in about two hours, and while fire crews attended the scene there was little they could do about a blaze 80 metres up in the air.
The company's root cause analysis found that the separation happened where the fiberglass laminate of the blade meets a pre-cast blade "root," adjacent to the turbines' revolving hub, a spokeswoman for Siemens said. Seven blades are being replaced at the Ocotillo plant as a result of the inquiry
PSE spokesman Ray Lane said he's awaiting word if wind farm employees can come back to the facility to check on the condition of turbines and associated high-tech equipment that might be affected by soot and ash that's fallen from the fire ...The turbines have been in "paused" mode as the fire approached and are not generating electricity. Lane said evaluation today may allow to go back into operation, or it could be another day before they are operational.
The Mehoopany Wind Farm, operated by BP Wind Energy, is the site of a helicopter crash that claimed the lives of five people Saturday night. It took off from Tri-Cities Airport in Endicott earlier that evening.
"But when weather becomes a factor, and I'm thinking about 9:30 , 10 o'clock last night when they said this may have occurred, it was very nasty and visibilities were quite poor," Zampetti said. "Why the helicopter got into this area, no idea. But any time weather becomes a factor, you're messing with disaster."
Recently there have been several units shut down while 10 blades were repaired. If each came from a different turbine it would mean the wind farm was producing 10% less electricity than planned while the turbines were out of service. It could also support the contention that the life of wind farms will be less than planned.
Unsure of what to do with its broken turbine, Union Township officials have tabled making a decision until the township consults with Central Michigan University. The north Skystream, a $16,634 grant-funded wind turbine installed for research purposes, no longer works, and the city is not sure why.
Turbines show up on radar and are difficult to distinguish from small aircraft, so RAF planes steer six miles clear of them. But with Typhoon jets due to move to Lossiemouth next summer, and the number of turbines nearby growing, air force bosses say they are struggling to cope with further developments.
Hardly three weeks after it was installed with much fanfare, one of the leaves of the windmill at the Marine Drive came off a second time in heavy rain and wind on Thursday afternoon leaving the Greater Cochin Development Authority (GCDA) with egg on its face. ...the company had undertaken the project on a trial basis and would replace it with solar power if the windmill was found unsuccessful.
"I've talked to a lot of people familiar with lightening strikes in other projects and they have spent lots of time, money, and engineering to chase down the source of the problem, and in the end there is nothing you can do to solve a severe lightning strike," Shah said. "...Turbines get hit by lightning all the time."
Fuses in the turbine have been replaced, but the troubleshooting of systems that "come into play in extreme circumstances" is continuing, Shah said. Determining whether there are problems with the any of the systems requires the turbine to be running.
The Forward Energy wind farm was constructed by Invenergy. The fire took place on a turbine located in the southernmost part of the project. Invenergy supplied a statement Tuesday that said its staff, along with local firefighters, were on scene of the fire that eventually burned itself out.
The wind turbines installed in Livingston County's Genoa Township 3 years ago are scheduled to be torn down within the coming weeks. The Genoa Township Board says the turbines are hazardous and have sent aluminum parts flying into surrounding areas on windy days.
The wind turbines that were installed on the Genoa Township hall property will be coming down for safety's sake.
A British diver was killed while performing underwater work at the 108 MW Riffgat offshore wind farm, located north of Borkum in the North Sea. The 26-year-old was buried in 20-meter water depth by a concrete mat, Die Welt reports.
The reinstalled windmill has only three fan leaves, compared to the original five, and the shaft thickness has been increased from two to five inches, said sources. "As we have high winds at Marine Drive, especially in the morning, we have reduced the number of wings in the windmill.
"We know that wake turbulence is an issue and when you look at the safety regulations administered by CASA (Civil Aviation Safety Authority), there are wake turbulence separation regulations," he said. "What we don't know is whether that translates directly to wind turbines."
Malcolm Barlow says the proponents of wind farm projects should have to make a significant fire fighting contribution to the local council. He says aerial resources represent around 40 per cent of fire fighting capacity. "Pilots are loath, understandably, to fly anywhere near wind turbines especially in smoky conditions," he said.
Although no one was injured in the Ardrossan event, it is still being scrutinised by the UK government's Health and Safety Executive, which polices workplace safety. "We're in the middle of an investigation to see whether a criminal offence has been committed," says Karl Turner, spokesman for the HSE.
The Independence wind turbine is offline after damage to its computer system during this weekend's electrical storm.
