A part of the wind turbine prototype “Vertical Sky A 32” with vertical rotors crashed on the wind test field during gusts. One of the three rotor arms and the 54-meter long rotor blade were in the field. Nobody was injured in the accident.
A fire in a wind turbine in Germany’s Lower Saxony on January 18 prompted warnings from local authorities to keep windows and doors closed in nearby areas while authorities tackled the blaze.
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.
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 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.
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 cause of the accident is currently under investigation. Mayor calls for construction freeze
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.
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.
A wind power plant located between Oldersbek and Rantrum (North Friesland) burst into flames on Monday.
On Thursday, a wind turbine burned in Lathen (Emsland). The total loss, according to police was about 500,000 euros. The fire was believed to have been caused by a defective gearbox casing. Firefighters were at the site in the morning but the situation was not under control until afternoon. By the time they arrived the nacelle and the rotor blades were already in flames.
Early morning, last Saturday a windmill near Brandenburg an der Havel lost a blade. The failure occurred after having operated for just 14 years. The life expectancy was at least double that number of years. The citizens' group "Save Brandenburg" warns of the dangers of wind turbines.
