METHOD AND SYSTEM FOR PERFORMING MAINTENANCE, SUCH AS, FOR EXAMPLE, DE-ICING A WIND TURBINE BLADE

Abstract

The invention relates to a method for performing maintenance on a rotor blade of a wind turbine rotor comprising at least one first rotor blade with an airfoil body formed from a blade envelope element, the airfoil body having a suction side surface and a pressure side surface, a leading edge and a trailing edge, as well as a root end for mounting on a wind turbine hub and a distal tip end. The method comprises the steps of immobilizing the wind turbine rotor, inserting 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 blade location with said mobile maintenance device, and removing said mobile maintenance device from said first rotor blade.The invention also relates to a system for performing maintenance on a rotor blade of a wind turbine rotor.
