In early 2007, Vestas decided temporarily to withdraw its V90-3.0MW offshore wind turbine from the market due to problems with the turbine's gearbox.
During the summer/autumn of 2007, the cause of the problems with the gearbox was mapped and at the moment, the gearbox is taken through the last steps in Vestas' quality assurance model. Based on the positive results from the already completed tests, Vestas has decided again to release the V90-3.0 MW offshore wind turbine for sale effective from 1 May 2008.
