Britain The Times April 16, 2005 Wind farm fears as blade snaps By Katrina Tweedie A TURBINE at a Scottish wind farm has broken down after one of its blades snapped off. The 10-tonne turbine, one of 31 at the £80 million Crystal Rig wind farm near Dunbar, East Lothian, was destroyed last week when a mechanism to stop it spinning too fast failed. Onlookers reported strong winds and said one of the turbine blades flew off and hurtled into the countryside. The 60ft high steel turbines are designed to withstand wind speeds of up to 60 miles per hour and owners, Fred Olsen Renewables, denied the breakdown was wind related. A spokesman said they were investigating the cause and that there had been little risk to people at the remote wind farm. The turbines from German firm Nordex were installed in August 2004. It will cost an estimated £1.25 million to repair. Anti-wind farm campaigners said the incident confirmed their fears about the danger of blades flying off wind turbines. David Bruce, of the pressure group Scottish Wind Assessment Project, said: “There were high winds so the turbines were ‘feathered’, or locked so they couldn’t spin round. It was lucky nobody was walking below. This is only about the second incidence of this in the UK but it shows this is possible.”

Typhoon Maemi struck Miyakojima Island on September 11, 2003 with an average wind speed of 38.4m/s and a maximum gust of 74.1m/s, recorded at Miyakojima meteorological station. All six wind turbines operated by Okinawa Electric Power Company were extensively damaged. Two Micon M750/400kW turbines collapsed by the buckling of the towers and one Enercon E40/500kW turbine turned over due to the destruction of the foundation. The other three experienced broken blades and damaged nacelle covers.
