Question noone has mentioned is why wasn't the S76 at Willytown used. The 76 is vastly superior to this sort of work, landing on the ship that is, compared to a 412. The crews, both front & back seaters, probably have a lot more experience in this type of flying too.
Casting your memory back to 1983 a 76 landed on the Key Biscayne, a jack up oil rig about to capsize, several times while a 205 had to try to winch as it couldn't land due to its inferior landing gear for this type of work.
Not doubting the crew did their best but were they the best crew available?
