To prevent further damage and ensure continued production, these gearboxes were replaced by Vestas Wind Systems a/s, the manufacturer of the wind turbine generators. Meanwhile a modified type of gearbox has become available which will ultimately be retrofitted to every wind turbine. This replacement project is handled by Vestas under the contractual guarantee and will continue into 2009. The work is being carried out from a crane vessel that can sometimes be seen at work in the wind farm.
