London-listed TRIG said that routine inspections had identified signs of stress fatigue on certain areas of the support structure of the helihoist on some of the 6MW wind turbines manufactured by GE. “Generation at the wind farm was paused as a precautionary safety measure whilst the root cause of the issue is being investigated,” TRIG said in a statement.
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
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?
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.
When on New Year's Eve he walked along the Mähneweg near Bocholt, a chunk of ice crashed to the ground just a few meters from where he stood. "I've got a huge horror, of course," he says. The approximately 60-centimeter (nearly 2-foot) ice piece had flown down from a 98-meter high wind turbine.
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.
