Apparatus and method for removing equipment parts from a platform of a wind turbine generator, and method for filling a fuel tank on said platform

A system, comprising:

• a wind turbine generator including a tower and a platform mounted to the tower;
• a housing on the platform including a housing support for supporting equipment within the housing, the housing support including first and second elongate equipment support rails;
• and
• an apparatus for removing the equipment from the housing on the platform of the wind turbine generator, the apparatus comprising:
• a winch for withdrawing the equipment from the housing in a substantially horizontal direction, the winch including a tension line which, prior to removal of the equipment, is arranged to be connected to the equipment, the winch being arranged to drive and gather the tension line thereby to withdraw the equipment from the housing;
• and
• a portable support structure arranged to support the equipment during its withdrawal from the housing, wherein the support structure is generally U-shaped with an open end and an opposite closed end, the support structure defined by two elongate slide support rails forming lengthwise legs of the U-shaped support structure and a cross bar forming the closed end of the U-shaped support structure,
• wherein the elongate slide support rails are respectively aligned with the first and second elongate equipment support rails at the open end to form a substantially continuous surface over which the equipment is arranged to slide.
