Abstract
A disassembled wind turbine under repair includes a tower secured to a foundation and a nacelle mounted atop the tower. The nacelle includes a base wall, side walls, a front wall, a rear wall, and a top wall. The front wall includes an opening configured to receive a main shaft of the wind turbine; however, the main shaft and a rotor of the wind turbine have been removed from the nacelle during a repair procedure. As such, the disassembled wind turbine further includes an external platform assembly secured at the opening of the front wall of the nacelle during the repair procedure.
