The replacement of the six AREVA wind nacelles has been completed at Germany’s first offshore windfarm, alpha ventus. All twelve wind power turbines can be put back into full operation. Work on the nacelle exchange began in September and was completed successfully today.

An increase in the temperature of the sliding bearings of the AREVA Wind M5000 power turbines was noticed in the spring, causing two turbines to be taken out of operation. As per the AREVA maintenance concept, a replacement of the turbine house, or so-called nacelle, was required in order to change the sliding bearings. First, the two out of service turbines at positions AV07 and AV09 in the farm were replaced so that they could be put back into operation successfully. Afterwards, the turbines at positions AV 08, 10, 12 and 11 in the farm were replaced.
