Abstract

An integrated approach to optimising the performance of a blast wall system G. Schleyer," D. Galbraith^ & I.

The work was undertaken to accurately predict the capacity of the blast wall and provide suggestions of how to improve its blast resistance. INTRODUCTION The Piper Alpha Inquiry by Lord Cullen [1] and following Safety Case legislation for offshore installations has increased awareness of hazards and their consequences. As a result, structures are being
