A New Scheme for Management-of-Change Support Based on HAZOP Log

Abstract Consistent and effective Management of Change (MOC) is the most important for process safety. Therefore, MOC should be logically and explicitly realized based on Tobe reference model. In this study, a new scheme for MOC support based on engineering activity model through the plant-lifecycle is proposed. Practical and effective utilization of HAZOP logs obtained at plant/process design phase in reusable form by using an intelligent support tool (HazopNavi) is archived.
