The problem is that the modern safety culture wants HAZOBS which are conducted before a campaign. In these sessions, the oil company SMEs are expected to put barriers in place to show that Hazard A or B is managed to ALARP.
Landing on an unmanned helideck is seen as a big sin "what happens if the helicopter lands on the deck and the crane is moving or it crashes and there is no helideck crew"
The oil company aviation adviser, busily trying to defend himself, the pilots and the helicopter company against an ever increasing number of self appointed armchair experts dreaming up ever more ridiculous scenarios has to trot out the usual barriers, FMS, flight planning, positive ID on final approach, etc.
The facilitators (paid by the word probably) then try to encourage the group to think of even more ridiculous scenarios to justify why landing on the wrong deck is a sin just short of murder. No one to man the fire monitors for the helicopter coming in to land if it's on fire, or the wheels won't come down etc. they don't realise that helicopters don't land offshore with known problems unless there is no alternative.
So the facilitators wind up the non experts who want to be experts because they once flew a model helicopter and before you know it, everyone is an expert and landing on the wrong helideck is immortalised as a sin, it self perpetuates over a few HAZOBS and we are where we are.
That's why the crew is suspended. As HC says, no big deal, a red face and bruised pride but it's not the sin it is made out to be. But because of the number of instant experts, even the strongest oil company Aviation Advisor finds it hard to reduce the hysteria.
