| Research Abstract |
In these days, safety becomes a social strict requirement in the process industry. An incident influences the competitiveness and/or sustainability. Therefore, PHA (Process Hazarad Analysis) has been carried out through the lifecycle. However, incidents and/or disasters occur as ever, and many incident investigation reports point out incompleteness of PHA, and reputation of past experienced similar incidents. To overcome this problem, mechanism to exchange hazard information including experienced incident through the lifecycle, and mechanisms to make consistency between PHA and IPL (Independent Protection Layer) design.
In order to represent hazard and/or incident information as a generic exchangeable knowledge, the process structure and causality of process abnormity are represented independently, and the causality is considered for every equipment unit class. The equipment unit instances in the process structure are associated with equipment unit class, so that the propagation of abnormal situation through the process structure are represented by using the generic knowledge of equipment unit classes.
Moreover, to maintain safety through the lifecycle, IPL should cover all the identified hazard by PHA, and IPL is to be designed based on results of PHA. In this study, adding a function to evaluate risk in PHA, risk based IPL design method is proposed. The methodology is applied to alarm design for the first step, consistent alarm design for an example PHA problem.
