A System Theoretic Approach to Support HAZOP Studies

Abstract

The approach we present in this paper is to assist the engineer in tackling the HAZOP wicked problem with software wizards that implement a number of functions such as providing to do lists for plant sections, lines and major vessels to be analyzed; recording pros and cons of proposed preventive strategies; displaying sections of the plant with similar pressure values; finding information on previously carried out tests that relate to the consequences of the abnormal situation under study; capturing design rationale. This paper discusses approaches to be implemented by the wizards.
