Latest developments in software technology allow for the management of the complete Process Safety Lifecycle as defined in standard IEC-61511 for the Process Industry. Most companies in the Process Industry have accepted the necessity of conducting Process Hazard Evaluations e.g. HAZard and OPerability (HAZOP) studies and Layer Of Protection Analysis (LOPA), however it has been more challenging to follow-up on the recommendations and demonstrate that the Safety Instrumented Functions have been built and tested in accordance with the design specifications. Validating the assumptions of the Safety Study and a comparison with actual Process Safety performance in the Plant has proven to be cumbersome and was almost impossible in the past. Furthermore, there was little insight in the financial impact of Process Safety risks. Modern Technology facilitates the validation, hence allowing for the management of the entire Process Safety Lifecycle. Real measured Lead Process Safety KPI's can be produced, controlled and managed.
