Abstract
Methods for performing maintenance on a rotor blade of a wind turbine rotor comprising at least a first rotor blade with an airfoil body formed from a blade shell element, the airfoil body having a suction-side surface and a pressure-side surface, a leading edge and a trailing edge, and a root end for mounting to a wind turbine hub and a distal tip end are disclosed, as well as a related system for same. The method comprising the steps of bringing the wind turbine rotor to a standstill, introducing a mobile maintenance device into said first rotor blade at the blade root, moving said mobile maintenance device inside said first rotor blade to a location, performing a maintenance operation at the location with said mobile maintenance device, and removing said mobile maintenance device from said first rotor blade.
