In the early eighties we S76A pilots, as well as running our own rig and platform support, formed the FART (Fast aircraft Rescue Team).
This involved carrying engineers, spares and sometimes pilots to stricken 332s and 214s. The offending aircraft would be pushed over to one side of the deck, the blades tastefully arranged and tied down and we would land in the remaining space.
The alternative was to send out a 332 with a winch but the chaos caused by the downwash whilst hovering over the deck meant that the direct 76 land on was preferable.
On a standard North Sea deck there was stacks of space.
