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.
A Kenersys K110 2.4 megawatt wind erected in 2012-2013 experienced a catastrophic blade failure. The blade was nearly 55-meters long. The turbine has a hub height of 145 meters and rotor diameter 109 meters.
A police spokesman reported that the fire initially broke out in the nacelle at around 3 o'clock on Friday morning and spread to the entire turbine. One blade of the wind turbine fell off after a short time while large parts of a second blade followed. Although the third blade did not burn, it threatened to fall after the nacelle was largely destroyed.
Baur calculates: Since 2016, there have been 16 fires, 15 blade and nacelle accidents and 4 tower damages involving wind turbines in Germany. With tons of equipment and high rotor speeds, there is a "high risk potential for people and buildings in the area".
Many wind turbines are now 20 or even 25 years old. This increases the risk of serious accidents, of which some failures have already been reported. TÜV therefore demands the introduction of a mandatory inspection program in Germany.
The damaged turbine at the Alpha Ventus offshore wind farm is set to be repaired with a replacement nacelle.
Wind turbine between Löcknitz and Rossow in Germany bursts into flames. Cause possibly due to a lightning strike.
The damage at the offshore wind farm, "Alpha Ventus", located about 45 kilometers from Borkum, is considerably more serious than initially known. At the beginning of April not only did the plastic covering crash 90 meters into the sea, but half of the nacelle fell off as well. Experts are now investigating whether it is a single incident or possibly serial damage. More than 120 turbines of this type are installed in the North Sea.
The citizens group, Gegenwind Borchen, shows on its website photos of fiberglass parts of shredded turbine blades scattered several hundred meters away. The fragments are from an Enercon E-115 turbine that experienced a catastrophic failure within days of the turbine being erected. The mayor of Borchen, Reiner Allerdissen, called for an immediate halt to construction at the facility until the cause of the failure is known. The turbine stands about 200 meters (656 feet) high.
The cause of the accident is currently under investigation. Mayor calls for construction freeze
A wind turbine lies in a field after it collapsed during storm 'Burglind' in Volksdorf near Hanover, Germany. The 70-meter tower collapse happened on Wednesday, Jan. 3 2018 after parts of the rotor had broken. Nobody was injured.
In the past four weeks, four giant power-generating wind turbines in Germany have either toppled over or experienced broken rotary blades. Now the question is: How safe are wind turbines really?
So far the investigation has found that one of three blades failed catastrophically, thus creating a huge imbalance that caused the tower to buckle 15 meters above the ground and led to the structure crashing down. ...The incident comes weeks after a similar turbine collapse in the Mecklenburg Pommeria town of Süderholz.
Three days after the disaster of a wind turbine near Leisnig in Central Saxony, a technical defect has been found as the cause of the accident. After completion of the investigation it was clear that one of three rotor blades was broken.
A wind turbine standing nearly 100-meters tall and sited near Leisnig in Central Saxony (Germany) collapsed after one of its three blades broke created an imbalance in the tower. According to the investigative report, the force of the impact imbedded the gearbox unit almost 2 meters into the ground.
Emergency services were called at 6am to the turbine near Wolf Lake in Isselburg in North Rhine-Westphalia to deal with a burning turbine. Investigators looking into possibility that a lightning storm was to blame.
A wind turbine in Germany burned for hours because fire fighters did not have ladders long enough to tackle the 100 metre high blaze. The flames struck this morning in the town of Isselburg in North Rhine-Westphalia.
The flames struck this morning in Isselburg in North Rhine-Westphalia. Emergency services were called at 6am to the turbine near Wolf Lake. Around 40 emergency personnel and six vehicles attended the scene. Investigators looking into possibility that a lightning storm was to blame.
On Friday morning, a wind turbine in Scholen (Diepholz) caught fire but for firefighters on the ground, there was little they could do.
