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.

Abstract: A bulkhead assembly for a wind turbine blade is described, wherein a pressure relief conduit is provided at the bulkhead to allow for pressure to equalise across the bulkhead. This helps to prevent faults or cracks in the bulkhead assembly due to differences in pressure on either side of the bulkhead. Furthermore, liquid traps and/or filter media can be accommodated in the conduit to prevent the passage of liquids or other matter across the bulkhead.
