The terrible price of North sea oil, 5 accidents with these 'copters in 4 yrs, cant be acceptable, easgach 1
From a human cost, no, it is not acceptable and can never be, from a statistical point of view, that is an extremely low failure rate for the number of miles flown and a rate that the authorities and operators have been working on reducing still further. Something like 1.9 deaths per 100,000 kilometres flown in the North Sea.
I get an email every time there is a death or reportable incident to the HSE (we use them as examples in the training) and Working at Height is by far the biggest killer, and I do not mean up the top or drilling derriks, its normally someone in an office or warehouse on a set of step ladders!
