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.
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.
LAHR Germany - Early Friday morning at 2.30 am police reported a turbine fire on the Langenhard near Lahr. At the same time, the Integrated Control Center Ortenau received the message that a wind turbine was burning on the Langenhard. The fire had already been seen on the way to the equipment house of the Seelbach Fire Department, said Operations Manager Bernd Wagner. This was his second wind turbine fire. The first was in 2013 - also on the Langenhard. Efforts to extinguish the fire remain highly dangerous because of the height of the turbine and the falling debris. Therefore, the fire department has cordoned off a radius of 500 meters, according to Wagner. A police helicopter was also requested to take survey photos and look for possible forest fires. The fire is over but the work is still ongoing. The fire department is preparing for a long operation.
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.
A lorry driver in Germany survived with minor injuries after a crash with a 62m-long turbine blade being transported to a wind facility. Autobahn 33 near Bielefeld was blocked for hours as the blade landed across the road.
The blade was knocked across the entire width of the autobahn when another lorry ran into the back of one of the transporter’s escort vehicles.
The giant blade of a wind turbine fell from the truck that was transporting it on Tuesday morning, squashing the cabin of another truck and completely shutting down traffic on a busy motorway.
The reason for the crash and the identity of the pilot both remained unclear by Thursday afternoon. But the plane reportedly hit the wind turbine at a height of 40 metres in relatively clear air.
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?
