Abstract
A power pack [] is located within a housing [] on the platform [] of a wind turbine generator tower. The power pack [] is supplied from a fuel tank []. With the door [] of the housing [] open, the power pack [] may be removed for servicing and repair by using a U-shaped support structure [] to which an electric motor [] is mounted. Two support rails [] permanently located within the housing [] support the housed power pack []. A chain [] attached to the power pack [] is driven by the motor [] to remove the power pack [] from the housing [] by sliding the power pack []along the support structure []. A pulley arrangement reduces the necessary torque. After removing the power pack [] from the housing [], a crane [] is used to lift the power pack [] from the platform [] and to lower it down to a sea vessel []. The crane [] may also be used in the refilling of the fuel tank [] by hauling a fuel line [] from a sea vessel up to the platform [] and connecting it to the fuel tank [
