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.
