This is one of the most interesting and informative threads I've ever seen, on any subject.
Overshadowing all the fascinating detail is the need for culture change. I promise you this scenario is not limited to offshore heli operations, but in most cases it does not have the grave effects we have seen here. The culture change has to be taken seriously by the line pilots but most especially by the senior management - as the line pilots will continue not to be invited to events like this until the management do take it seriously, and fully realise what 'culture change' means. I wonder if it would help to cite this thread in making it happen.
Sorry to butt in - please carry on.
