After the Cormorant accident in '92 or 3 Shell had a policy of no passenger flights with more than 50kt over the deck. In the far north this did build up some delays. A couple of years later I was called in off standby for a freighter and found the wind passed by the platform was 62kt. OPs, at my request queried the safety position with Shell and were told that the 50kt restriction was so that human life wasn't endangered. Ops asked the obvious before I spat my coffe all over the paperwork and were told that crew didn't count!
