Repairing Lightning Strike Damage

Published 19 February 2018

This case study explores how an incident of lightning strike damage was repaired at a UK offshore wind farm, after an End of Warranty (EoW) inspection found that three blades across the wind farm had been subject to lightning strike damage and required immediate attention. The Owner/Operator engaged with a service provider to execute the necessary rope-access repairs, despite harsh late autumn weather conditions.

To repair the damage, an industry standard technique was employed that involved exposing the affected area, then rebuilding fibreglass layers in-situ using rope-access technicians. The case study is based on experiences at an offshore wind farm in the UK that has been anonymised at the owner’s request.
