Absolutely agree with you - i flew with Steve Potton a couple of times (never knew the co-pilot) and found him very capable, careful and consistent. If it can happen to him, i'm not in any doubt that any of us - myself included - could be caught out.
Very sadly accidents will happen. I think the way to minimse this risk though, isn't to change our procedures in their entirety, but to improve our training with the procedures which are all ready in place (again with a few exceptions).
The only way to take the risk entirely out of night off-shore ops, is to stop night flying - which i don't think is commercially viable, or necessary.
