Abstract

The study proposes an integrated frame implemented based on HAZOP and fuzzy evaluation of risk matrix (used to evaluate the safety integrity level), the aim is the improvement of an industrial fired heater safety. The determination of target SIL of any safety-instrumented function by the conventional methods such as Risk graphs, LOPA…may give imprecise values due uncertainties, in both parameters and models. Fuzzy theory is a useful mathematical approach to deal with the problem of uncertainties, by applying the membership principle introduced by L.A Zadeh. In this paper, we will use the Fuzzy theory to evaluate the target SIL for HAZOP recommended safety functions of a fired heater. The results will be compared with other SIL values (called calculated SIL and deduced using practical data of Probability of failure under Demand (PFD values). Depending on these comparison, recommendations for improvement are raised. In our case and from the overall study more safety functions should be added and the design of others have to be modified to respect the required safety level.
