With large chunks of burning nacelle components and melting fibreglass blades falling from 80 metres above, there wasn’t much the West Pubnico Fire Department could do when a wind turbine fire was reported the afternoon of March 15.
Firefighters were at the scene quickly but could do little to battle the flames, West Pubnico fire Chief Gordon Amiro said. When the blades turn, the tips are more than 100 metres in the air — too high to fight the fire from the ground.
Firefighters were unable to get close enough to put the fire out directly because of the turbine's height and movement of the blades -- and it couldn't be turned off with the gearbox on fire. "It was too dangerous to get close to it," Amiro said. "Because of the length of the blades and the blades were turning, you didn't know where they were going to go when they fell."
"We couldn't get nowhere near because the blades was still turning, so, and pieces was breaking off the blades," he said. "So if a piece was to fall off, it would go a long ways with the wind and that. So it wasn't safe to go nowhere near the tower at all."
According to the wind turbine manufacturer, a lightning strike could have been the reason why the rotor blade broke loose.
Several roads were closed Monday morning after a wind turbine in the Hahnweiler / VG Baumholder wind farm experienced a blade failure.
Garner didn't speculate on what caused the wind turbine to fall over. However, other turbine mishaps that have occurred during high winds were because the turbine's braking system failed. Modern wind turbines are designed to shut off or slow their blades during high winds. If the blades turn too fast, it can cause the entire structure to become unstable and then disintegrate.
After sustaining damage from a fire last fall, the town’s second wind turbine is set to sit idle for the foreseeable future. Or it may be taken down by the operator, town manager Tony Marino told the select board this week. But the board also got unwelcome news when Marino told them the project was never bonded.
In the district of Uelzen, the blade of a wind turbine broke off during a storm and fell to the ground. An investgation is called for to determine the cause of the incident.
The wind turbine at Espinhaço de Cão, in the Aljezur area, is said to be well past its useful life and local fire chiefs have complained of the security of these machines and the threat they cause to the surrounding countryside.
The oft reiterated promise of “cheap renewable green energy” is a quixotic myth, fabricated by those who have an economic incentive to lie, championed by those with a political agenda to advance, and believed by those who are too intellectually lazy to do basic research. While there is no “free lunch,” there are practical, cost-effective solutions.
"The windmill stands so it is above the two-sided farm building that housed the bull calves. The blades fell into the building, and fire spread in the stable and the hamlet in there, which we tried to control," said Lars Stensbjerg, who is the leader of fire and rescue MidtVest.
The situation developed dramatically as one of the wind turbine blades which was in flames, fell into a nearby farm building that housed between 30 and 40 bull calves in the stable buildings.
The analysis of almost 3,000 onshore wind turbines — the biggest study of its kind —warns that they will continue to generate electricity effectively for just 12 to 15 years. The wind energy industry and the Government base all their calculations on turbines enjoying a lifespan of 20 to 25 years.
A spectacular accident on Monday morning: In a field between Gau-Bickelheim and Wallertheim near the A61 motorway, the almost 55-meter-long and ten-ton blade of a wind turbine was broken off shortly before 8 o'clock and crashed onto an adjacent field. Persons were not injured in the incident, fire department and police secured the accident site.
During Wednesday’s Huron County Planning Commission meeting, Blake Shroll, site manager of Big Turtle Wind Farm, told planners Big Turtle II experienced a failure on Tower 14 on Nov. 28. “We had two pieces of fiber glass fall within 100 feet of the base.
Investigation will begin by company officials after a wind turbine blade failure early this (Wed) morning in Bloomfield Township, west of Port Hope.
Several Queensland Fire and Emergency (QFES) crews attended the blaze, which ignited about 3pm. A QFES spokeswoman said crews stood by for safety in the event that it led to a grass fire.
The number of spinning giant turbines standing high above Gloucester's Blackburn Industrial Park is now, temporarily at least, down to one.
Every time a drop of rain hits a wind turbine blade it contributes to a process that ends in small cracks being formed in the leading edge of the blade that eventually ruin the coating on the blade. The bigger the drop, the worse the damage, reports DR Nyheder.
