1.0 INTRODUCTION
These guidelines have been developed and published under the sponsorship of the Health & Safety Executive supported by the Civil Aviation Authority and endorsed by the Offshore Industry Advisory Committee – Helicopter Liaison Group (OIAC-HLG) to provide technical information about the design and operation of helidecks and their facilities and to indicate current good practice. The OIAC-HLG membership is comprised of HSE, CAA, BHAB, UKOOA, BROA, IADC, IMCA and the trades unions TGWU and AMICUS (MSF).
Since oil and gas exploration activities began on the United Kingdom Continental Shelf (UKCS), the Offshore Industry has been dependent on the efficient and safe use of helicopters for logistics and emergency support. The primary role is moving people to and from their workplaces on the offshore facilities. Other roles include freight movement, emergency evacuation and search and rescue.
Over the thirty years or so since oil and gas activities commenced on the UKCS, helicopter travel has become the norm for the workforce. A measure of the scale of this vital activity since the early sixties is that there have been in the order of 6 million flights and 45 million passenger movements within the UKCS (1968 –2002).
The introduction of helicopters in the early sixties as a routine offshore ‘workhorse’ has increasingly brought the associated operational support activities into sharper focus. The harsh operating environment, some serious and fatal accidents and the emergence of goal setting regulations offshore have all contributed to a greater awareness of the problems associated with operating helicopters in a marine environment.
However, this greater awareness of operating problems has not always been matched by a full and clear understanding of requirements at the interfaces between aviation, oil and gas production and processing and marine operations.
