Abstract

An extensive hazard identification of a chemical plant as part of a sound safety analysis is not only highly recommendable but often subject to official approval of construction by the national governmental authorities. Since established methods, e.g. HazOp studies, are mostly carried out manually and thus still involve a lot of disadvantages, there has been a marked increase in the research of computer-based analysis methods in the last years. This project aims at introducing a new approach to process hazard identification by simulation and analysis. As a basis, a qualitative plant model formulated as statecharts has to be generated first which benefits from the lack of information at early design stages. HazOp-like simulations can be performed if stimulus to the model is given which corresponds to a HazOp guide word. In addition, special safety issues can be answered by reachability examinations of dangerous plant states in the model.
