The 332L is stronger than you think. I was offshore in the 40s for about 5 months with one and while we had some problems with blade sail it held up well. You have to have one greenie and one A+C engineer with you but as it was your a/c it was easier to keep on top of snags as they arose. The decks chosen for the SAR helio will have to be carefully selected to give some measure of shelter . I.e 40s OK especially from a SW wind Montrose not so good as the helideck sits right on top of the rig with no shelter. The BP idea is very good so long as the right decks are chosen and the a/c and crews are prepared and trained properly for the task.
