FOREWORD

This report is based on a dissertation Helicopter Safety at Offshore Installations submitted by the author in part-fulfilment of the degree of Master of Science in Safety Engineering, Reliability and Risk Assessment at the University of Aberdeen during November 1999. The report has been substantially revised and updated to include more recent information. Helicopter accident and statistical information was provided by John Burt Associates and from International Civil Aviation Organisation, CAA, HSE and other records. Several pilots and ex-pilots volunteered their views. Captain Mike Ginn of Consultavia Ltd, in particular, gave considerable assistance. The study provides background material about helicopter accidents offshore throughout western Europe not previously summarised elsewhere, a review of relevant reports and a bibliography of reference material and associated research. Conclusions are drawn by the author from this information and from his own experience of working offshore as an Offshore Structural Design Engineer and later as an HSE Inspector.

Since the original report was written, a major study carried out by SINTEF of Norway on behalf of seven oil companies and the Norwegian Civil Aviation Authority has been published. This study, Helicopter Safety Study 2 (1), was carried out independently at the same time as the dissertation was being prepared. Although the present report does not incorporate a detailed review of the Norwegian work, the concept of risk influencing factors, ie conditions affecting risks to helicopter passengers, aircrew, helideck crew and offshore workers on an installation, is common to both. The conclusions of the two studies are broadly similar.

The Health and Safety Executive of Great Britain (HSE) encouraged the author to undertake this project and made time available for research as part of his work as a Specialist Inspector with HID Offshore Division (OSD). I believe I have obtained a consensus view. However, the opinions expressed are my own and should not necessarily be taken to represent those of the individuals and organisations who contributed.
