Vestas began dismantling its 80, 2 MW turbines at the Danish Horns Reef offshore wind station last month to undertake repairs on land. The job will be carried out with the company's suppliers -- mainly ABB, which supplied the faulty transformers and generators (Windpower Monthly, June 2004) -- who will pay for their respective shares of the repair costs, according to Vestas' Svend Sigaard. The nacelles are being taken to Vestas' factory on the Danish North Sea coast, not far from Horns Reef. All transformers will be replaced, a yet unknown number of generators fixed or replaced, and some other "small" repairs carried out. All units are to be back at sea and operating by the autumn. Sigaard declines to reveal the cost of the operation, but the company does not expect the job to affect its expected bottom line result for the year.
