A test version of MHI Vestas' V164 turbine, the world's most powerful wind turbine at 9 megawatts, has caught fire.
A blade has been blown off a Vestas turbine at Bindesbol, western Denmark during storm Urd, local publication Dagbladet Ringkobing-Skjern reported last week.
Employees at Siemens Wind Power in Denmark have reported complaints of chronic illness from manufacturing wind turbines. In the last 10 years, at least 64 cases have been confirmed of employees becoming ill from exposure to hazardous chemicals in their job at the turbine facility.
Due to harsh weather, A2SEA's installation vessel, Sea Worker, has capsized off the coast of Nymindegab, Denmark. The evacuation took place on 27-Jan-2016 at approximately 03:10am off the North Sea coast by a lifeboat from Hvide Sande. The vessel was was in transit to Esbjerg.
A large turbine at a Samsø offshore windfarm was wrecked on Saturday, bringing electricity production at the site to a halt. For unknown reasons, the 100-metre-high turbine lost its top part and all of its wings, which then fell into the sea.
"There was a loud bang and then one of the blades span off, and shortly afterwards the gearbox's housing fell to the ground," Henrik Nielsen, one of the officials at the scene.
The blades and gearbox have been spun off a wind turbine in western Jutland after a malfunction allowed it to reach to dangerous speeds in high winds. ..."We cannot get close to it until the wind dies down,” Oluf Jakobsen, from the local Morsø municipality explained on Friday morning. “There’s nothing we can do but sit and wait for the outcome."
The incident involved a single V90-3.0 MW wind turbine, which uses 44-meter-long blades. Two of the blades were damaged ...A developer named Hojstrup Vind ApS owns the wind farm, which features four V90-3.0 MW turbines. The machines were commissioned in December 2013,
The Danish wind giant is dealing with fallout from a fire on one of its turbine models. A number of operating turbines were paused following the fire, and the company responded to media questions this week.
Dr. Mauri Johansson, MHH, a specialist in community and occupational medicine, delivered this speech at the general meeting of Vestas on Thursday March 29, 2012 in Denmark.
OSHA said Monday it has cited Vestas for one willful and 23 serious violations following an inspection of the wind turbine manufacturing plant. The inspection was initiated after an employee suffered a partial amputation of two fingers and a broken wrist in November. OSHA has proposed $164,000 in fines against Vestas.
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.
Wind turbine blades rip loose near Esbjerg and southwestern Sweden, one landing on a hiking path A malfunction on a Vestas wind turbine in the town of Falkenberg on Sweden's southwest coast could have resulted in tragedy, as one of the structure's large blades flew off and landed on a track used by hikers.
Following the catastrophic failure of two Vestas wind turbines on Feb 22 and 23, 2008, the Danish energy agency requested an investigation into the events. A report was produced by engineers at Risø DTU. Below is the report translated into English. The original report, in Danish, can be accessed by clicking on the link below. A video of one of the failures can be seen here: http://www.windaction.org/videos/14294 . It is important to note that the debris from the first turbine failure which occurred on February 22 spread as far as 700 meters (2200 feet) away. Risø DTU is formerly a government research institution under the Danish Ministry of Science, Technology and Innovation.
On February 22 a 600 kW Nordtank wind turbine at Halling in eastern Jutland experienced a so called runwaway event causing its blades to spin out of control. Minutes later the blades collided with the tower and caused the turbine to collapse. In an unrelated event at Vig in Odsherred a Vestas V47 600kW wind turbine lost a blade. In both cases, Vestas assume that human errors in service and maintenance caused the events, but points out that they are in process of finding the accurate causes.
The climate minister will begin an investigation into two separate cases of Vestas wind turbines collapsing within the past week The climate minister, Connie Hedegaard, is calling for an investigation to determine the cause of two violent wind turbine collapses in Denmark in the past week. Both of the windmills were produced by Vestas, and Hedegaard's request to the Energy Board comes after other breakdowns both here and abroad have been reported in the past two months.
This footage was taken at the moment a wind turbine in Denmark exploded in high winds. The braking system failed. Pieces of the shattered turbine were sent more than 500 meters away. A second video of the same event can be viewed by clicking here. Duration: 32 seconds
A windmill in Denmark collapsed during a storm in Denmark on Feb 22, 2008. The braking system failed while two technicians worked in the turret at the top. The technicians were able to get out before the collapse. Pieces of the shattered turbine were sent more than 500 meters away. Additional footage can be viewed by clicking here. Duration: 40 seconds
After the industry's recent boom years, wind power providers and experts are now concerned. The facilities may not be as reliable and durable as producers claim. Indeed, with thousands of mishaps, breakdowns and accidents having been reported in recent years, the difficulties seem to be mounting. Gearboxes hiding inside the casings perched on top of the towering masts have short shelf lives, often crapping out before even five years is up. In some cases, fractures form along the rotors, or even in the foundation, after only limited operation. Short circuits or overheated propellers have been known to cause fires. All this despite manufacturers' promises that the turbines would last at least 20 years.
