Narrative:
During a commercial Marine Pilot Transfer winching operation, the rotors of G-BDOC struck the top of a mast on the deck of the receiving ship. The helicopter recovered safely to Scatsta Aerodrome. The investigation revealed some misunderstandings between the helicopter operator and the maritime operator about the winching deck markings on the ship. Accordingly, recommendations have been made to the CAA and to The International Chamber of Shipping (ICS) to ensure that aircraft and ship crews are aware of the information required before undertaking winching operations. Shortly after the accident, the helicopter operator instituted revised rules to clarify the information required before any winching operation.
