Schaeffler Made Bearings for Faulty Vestas Wind Turbines

Schaeffler Technologies AG said it made the bearings in the gearboxes of 376 V90 wind turbines that Vestas Wind Systems A/S (VWS) identified as needing require additional repairs and maintenance.

“The mentioned bearings in the Vestas interim report are from Shaeffler,” Marcus Brans, a spokesman for Schaeffler, said today in a telephone interview. “We have some damage to the bearings on this type of turbine.”

Vestas, the biggest wind turbine maker, yesterday said it was providing 40 million euros ($53 million) more to pay for extra maintenance, repair or replacement of malfunctioning bearings in the turbines, including machines operating offshore. The gearboxes were supplied by ZF Wind Power Antwerpen NV, it said, without naming the bearings manufacturer.

“We will pursue all available avenues with regard to compensation for this,” Vestas Chief Executive Officer Ditlev Engel said yesterday in an interview. He cited “unexpected additional warranty provisions” as one of the reasons for a wider-than-expected loss in the first quarter.

Brans declined to comment on who would pay to remedy the faults.

“These are main rotor bearings that are fitted in the gearbox input,” Brans said. “These are currently being investigated by us to determine the cause of the damage and we are closely and constructively working with our customer on this topic. It’s an ongoing process.”
