Safety and Structural Failure
This was the second time in two years the school district had a wind turbine fail due to a problem with blades. The turbine that failed this week was not the one that had earlier problems, officials said.
"At this point we're going to take a step back, find out what happened and make decisions from there," Perkins school Superintendent Jim Gunner said.
For the second time in two years, Perkins Schools officials shut down the wind turbines on school property after a mechanical failure.
"I had several calls from concerned residents who saw the fire, which burned for over two hours," said local county councillor Paul Marfleet.
"I went up to the site and the police and fire service were there, but there was little they could do to tackle a fire 75 metres above the ground and I did sympathise.
The Bloomfield Fire Department responded to the emergency call, but the small fire burned itself out.
In late 2008, an explosion and fire in a turbine injured three workers during construction of the Elkhorn Ridge wind farm in northeast Nebraska.
One of Verve Energy’s wind turbines at the Esperance Wind Farm was hit by lightning last Saturday week, shredding the blade and making the turbine inoperative.
Technicians were at the site last Friday doing routine maintenance on other turbines and say that the damaged turbine has been made safe for the time being.
An investigation into a wind turbine that collapsed in New York State last year has found that wiring in the machine may have been "incorrectly" installed.
The state's largest wind developer, Noble Environmental Power, could now find itself required to gain third-party certification for other turbines it has built in the state to answer questions hanging over its operating practice.
As experts hone in on what caused a 187-ton windmill to collapse in a Fenner cornfield last year, developers are moving forward with a plan to get the rest of the wind farm's 19 turbines safely spinning as early as mid-July.
Turbine 18 fell to the ground in the early hours of Dec. 27, shocking neighbors who have lived among the windmills for nearly a decade and industry experts who called the failure unprecedented.
Officials at NextEra Energy Resources aren't sure what caused one of the three blades on a wind turbine south of the village of Shabbona to fail Friday morning. The 131-foot-long blade hung from the top of the turbine Friday, apparently bent at the base and split along its length.
Hundreds of offshore wind turbines could be suffering from a design flaw that makes them sink into the sea.
Energy company engineers are urgently investigating the extent to which their offshore wind farms are affected, after flaws were discovered on a Dutch wind farm last autumn.
The problem could cost £50 million, said Renewables UK, the industry body that represents wind farm developers.
Hundreds of offshore wind farms are being checked for a construction fault after a flaw was discovered in one of the Europe-wide industry standards.
The problem that has emerged is over the turbines' "monopile" foundations. The issue is centred on the grouting in the transition piece linking the turbine to its foundation, and the towers that are affected have shifted several centimetres under the impact of harsh offshore conditions.
How safe would giant wind turbines, power stations, high voltage lines, and a dump proposed for East County be during a powerful earthquake? Consumer advocates and area residents are raising those questions-and the answers in some cases are unsettling.
A construction flaw in the foundations of many sea-based wind turbines was not discovered by inspectors who approved the structures' operation
One of the most common foundations for sea-based wind turbines has a critical flaw but was nonetheless approved by a Nordic certification company, reports trade journal Ingeniøren. ...‘It's something no one could foresee and can give any engineer nightmares,' he said.
Early Monday morning, a 20-foot-plus piece of one of the blades on Bartlett's Ocean View Farm's wind turbine snapped off and fell to the ground nearby.
The wind turbine immediately shut down. There were no reported injuries when the blade struck the surrounding farmland, said John Bartlett.
Workers are inspecting and repairing 75 wind turbine blades at a wind farm some 60 miles east of San Diego after a storm a month ago caused catastrophic damage to some of them. ..."The turbines were actually stopped," he said. "There were extremely high winds on the site - that contributed to the blade cracking."
Buyea Road resident David Kalenak said the crumpled remains of the wind turbine attracted hundreds of onlookers throughout the day on the rural road, which usually sees just one or two cars each hour.
"I think a couple of my neighbors are a little nervous," said Kalenak, who didn't hear the crash. "This one was in a field, but others are in the line of homes."
Local residents are wondering if one wind turbine could collapse in Madison County, then it is very possible for a turbine to fall anywhere.
Fairfield resident Jim Salamone thinks why couldn't it happen in his back yard.
Salamone ...says he was not surprised when he woke up to find out a wind turbine had collapsed in Fenner. He says the meteorological tower that used to be right across from his home already collapsed because of wind and ice.
The wind storm that knocked over the crane had similar negative effects on the local residential wind-powered electric generators. The storm, which blew at least 125 miles per hour, completely dislodged the helix shaped turbine that was installed on Haystack hill. The blades and shaft blew away and were later located by divers. The tower stayed up.
Children at an island primary were sent home after a newly-installed wind turbine next to their school collapsed, it emerged yesterday.
Parents of youngsters at the 18-pupil Raasay Primary School were asked to collect their children following the incident on November 13.
The 50ft turbine will "remain out of commission" until an investigation has been carried out.
An entire fleet of around 100 'urban' wind turbines has been remotely shut down by manufacturer Quiet Revolution after the discovery of a design fault.
The fleet of QR5 turbines was disabled after continual wind speeds of between 14 and 24 metres per second caused a turbine located on a sea wall in Blackpool to develop a mechanical error, the company said in a statement on Friday. The QR5s have been installed on 55 sites for clients including Network Rail, Sainsbury's and self-storage firm Big Yellow.
A transformer at the Maple Ridge Wind Farm's substation off Rector Road was destroyed by fire late Monday afternoon.
Martinsburg firefighters were dispatched to the substation about 5 p.m. but had to wait until the facility was shut down before extinguishing the blaze, said Lewis County Fire Coordinator James M. Martin. ...The Columbus Day fire was the second transformer fire at the site, with a similar incident occurring July 4, 2007. In that case, 491 gallons of mineral oil leaked from the damaged transformer
