Captain David Pearson explains: “Periodically the UK and European Coastguard helicopters do a safety drill on various vessels. They prefer to try and drill on vessels that have particular issues with the amount of free deck space. This is so when or if they have to attend in an emergency they have experience in landing the crew members in a restricted space.
The technique they use is called the High Line Technique, which means they lower the crew member on the winch line away from the vessel and then when he is level with the landing area they manoeuvre the helicopter in towards the target area. They then recover the crew member in the same manner.”
