Gasax, I'm sorry but "Given the workforce have no say in the matter, or influence over it, makes them a hostage to fortune." is an overly dramatic, non-poetic way to say "in it for the money."
Anyone who works offshore can re-locate to the beach anytime they want to, there are no hostages real or perceived, it's a personal choice, with choices.
And as for "the helicopter companies and the CAA have been pretty complacent over a non-improving accident rate." In your role as a Technical Risk Assessor for the offshore industry how have you reflected this? Or have you skirted over this to keep your employer happy and look after your own interests? I'm sure there are plenty of people on this thread happy to discuss the impact of Energy companies, and their 'experts', their requests for rate reductions? Their own individual requirements as apposed to the OGP or other industry requirements to be 'special', the impact of their flight programme with the single aim of keeping the offshore workforce happy and not the best human factors approach, and there are many more... So having identified yourself as a technical risk assessment professional what have YOU done to work with your company to make things safer? ...or is it someone else's problem, OEM's, Operators etc?
