Scots wind farm shut over safety fears after 150ft turbine blade falls off


EUROPE'S largest wind farm ground to a halt after a 150ft blade snapped off one of the turbines.

All 140 of the giant machines were immediately shut down at the £300million development near Glasgow until they could be inspected.

Engineers at Whitelee wind farm, which is run by ScottishPower Renewables, were trying to work out why the blade came crashing down.

They are looking into whether lightning could have struck the turbine or if it was caused by a mechanical problem.

It sheared off and hit the ground in the early hours of Friday morning in blustery conditions.

Automatic systems alerted operators in the control room to the damage and they immediately closed down the unit.

All 420 blades in the wind farm were being examined following the accident.

Last night, more than 50 turbines were expected to have been inspected and safely returned to operation.

The process is expected to be completed by Friday.

Whitelee wind farm's visitor centre, which is managed by Glasgow Science Centre and had been due to reopen after the winter break yesterday, stayed shut.

German company Siemens, who supplied the turbines, are also understood to be investigating.

The 360ft turbines are so massive that engineers have been able to climb inside them to try to detect the problem.

Over the weekend, the site at Eaglesham Moor, 13 miles from Glasgow city centre, was cordoned off to keep visitors away. Raymond Toms, 45, a teacher from East Kilbride, spotted the broken turbine as he cycled past on Sunday.

He said: "I was out for a bike ride and I saw one of the massive blades had broken clean off. It was quite unnerving really.

"You can walk right up to these things normally and touch them.

"The public have access to the network of pathways nearby.

"I have grave concerns over the safety of the public, who can walk right up to the turbines.

"It's worrying that if one of these could fall off then perhaps another one could.

"It's made me think about going too close, that's for sure. It's just lucky this took place at night, when nobody was around."

Keith Anderson, managing director of ScottishPower Renewables, said: "This type of incident is exceptionally rare and highly unusual.

"However, the safety of our people and the public is our first priority.

"While the investigation into the cause of the incident is ongoing, our engineers continue to conduct an internal and external examination of all turbine blades at the wind farm".

A spokesman for the firm added: "Investigations are ongoing, and a number of possibilities including mechanical failure and lightning strike are being considered.

"Operators in the 24-hour control room immediately closed the turbine down.

"This is a highly unusual situation. I've not heard of this kind of incident happening in 30 years."
