GETTING FULL VALUE FROM HAZOP: A PRACTICAL APPROACH TO THE ASSESSMENT OF RISKS IDENTIFIED DURING STUDIES ON PROCESS PLANTS

摘要

Busy plant managers working under time and budget pressures may be aware of the HAZOP technique but doubtful if it is suitable to apply to an existing operation let alone deliver a payout on the time and expense involved. This paper summarises an approach to HAZOP studies on operating plant which has delivered positive benefit cost for relatively little additional effort over and above that required for conducting the HAZOP itself.
