I work in technical risk assessment for the offshore industry. When you calculate the risk which the workforce are exposed to, helicopter flying is a significant element. It depends upon the age, layout and complexity of the installation but on a modern platform the transport risk is typically 30 to 40% of the total risk.
Apart from the drive to and from the airport, of course!
When they pay to fly it is fixed wing (virtually always) and typically about 100 times safer than flying in a helicopter
Nonsense! Globally the figures are about 7 times and for IOGP members around 3-5 times. Hence, the Shell 7/7 = 1 initiative 10 years ago.
