During construction at a Krampfer wind farm, the rotor on one of the 200 meter high wind turbines crashed to the ground. No one was injured.
"The workers were outside the danger zone and operating the crane by remote control," says Rolf Peters from the company Nordex of Hamburg. It is still unclear why the 60-ton rotor blade crashed with the blades mounted. "We will check if a gust of wind hit the rotor or if there was human or material error," said Rolf Peters. Estimated damages amount to several hundred thousand euros but the exact cost has not been determined.
Eyewitnesses claim to have seen the rotor crash from about 60-meters high. According to an eyewitness, a gust of wind may have caused the rotor to strike the tower before falling. There may also be some damage to the turbine foundation, which, if the case, would place the stability of the system at risk. "Then we would have to rebuild," explains Rolf Peters. Construction has stopped at the site until the cause of the accident is determined. The estimated cost of a new wind turbine is about 5 million euros.
