Blazing Turbine 'Like a Catherine Wheel'

The turbine which caught fire had been suffering from an oil leak and had been undergoing repairs earlier in the day. Engineers thought they had fixed the problem, but when they tested the turbine it caught fire.

Wind Turbine on Fire (1)

Getedimage.aspx_thumb A HUGE wind turbine went up in smoke in a massive blaze seen for miles across Wearside.The 200ft structure at the Nissan factory, part of a £2.3million wind farm built in August, burst into flames just after 12.30pm yesterday. The fire was so fierce all three 75-ft long fibreglass blades eventually dropped off and thick black smoke could be seen for miles around. Almost 200 people dialled 999 to alert emergency crews as flames engulfed the turbine. Police closed both the A1231 and the A19 for an hour-and-a-quarter amid worries that parts of the metal tower could fall on to the busy roads. The six turbines were bought second-hand at a cost of £1.1million, having been previously used on a wind farm in Germany. Graham Bagley, from Nissan, told the Echo in August it did not make financial sense to buy new ones and claimed the turbines were in "excellent condition". A spokesman for Nissan denied the turbines are unsafe. "It is the same design that has been used in wind farms all over the world and as far as we're aware nothing like this has happened before," he said. "If there had been any concerns about the turbines we would never have purchased them. "We're taking this very seriously and until we know what has caused this all six turbines will be shut down." He said engineers from Vestas, the company who manufactured the devices, had been working on the affected turbine since an oil leak was detected on Thursday. "It was the third turbine and is the nearest one to our test track," the spokesman said. "Engineers were repairing it yesterday morning and they had restarted it when the fire started. As far as we are aware it was oil that caught fire and the blades then burnt through. They are made of fibreglass and they burnt right down to the metal shaft before falling off. Nobody was hurt. We have now shut down all the other turbines and engineers are carrying out checks on all of them. We apologise for any inconvenience that may have been caused by this." Both the main roads were reopened at 2pm. A spokeswoman from Tyne and Wear Fire Service said: "We had seven fire engines in attendance and because of the risk of the structure falling onto the A19 police closed the road and the A1231. "The majority of the structure eventually fell away from the road."

Damaged Turbine Crystal Rig wind farm near Dunbar (1)

Damage_crystal_rig_thumb 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.”

Assessment of Safety Risks Arising from Wind Turbine Icing

Assessment_of_safety_risks_arising_from_wind_turbine_icing_thumb "Developers and owners of wind turbines have a duty to ensure the safety of the general public and their own staff. However, there are currently no guidelines for dealing with potential dangers arising from ice thrown off wind turbines. This puts developers, owners, planning authorities and insurers in a difficult position. To rectify this situation, the work presented here has commenced in order to produce an authoritative set of guidelines. Initial work has resulted in the development of a risk assessment methodology which has been used to demonstrate that the risk of being struck by ice thrown from a turbine is diminishingly small at distances greater than approximately 250 m from the turbine in a climate where moderate icing occurs."
