During the past twenty years the wind turbine technology has experienced a remarkable development. Denmark has played an important role in this process, and Danish wind turbine manufacturer as Vestas, NEG Micon and Bonus are among the top 10 in the world. In the western part of Denmark the installed wind turbine capacity comprises today more than 2.300 MW and wind power suplies approximately 18 % of the power consumption. Elsam A/S owes and operates 450 wind turbines ranging from 150 kW to 3 MW units. By the end of 2002 the Horns Reef offshore wind farm was put into operation. The wind farm is situated 14 - 20 km west of Esbjerg in the North Sea and the site consists of 80 wind turbines each of 2 MW supplied by Vestas Wind Systems. The capital investment in off shore wind farms is high and maintenance is both difficult and very expensive. A major objective in this project was to minimize the risk of gearbox failures and this paper presents the views regarding design of the gearbox lubricating system, running-in of the gearbox before commissioning and the selection of lubricant for these units.
