Enercon turbine failure
1 March 1999
Enercon is still investigating the cause of a failure of an E40 500 kW turbine on January 17 when the nacelle and rotor toppled off the tower, reports Klaus Hilgenstein, managing director of Vogelsberg Windenergie, the company that owned the turbine. It was one of three installed in the Vogelsberg hills near Ulrichstein. The two other machines, though working normally, are also being investigated. Enercon replaced the destroyed nacelle and rotor within four days of the incident, taking the damaged components to its main facility at Aurich for inspection, says Hilgenstein. The incident happened in winds gusting up to 30 m/s. The machines are sited in a field and nobody was hurt, he adds. They were installed at the site in December 1996. "Clearly it is in Enercon's own interests to establish the exact cause," Hilgenstein comments. "We are in close contact."
