Business Process Model Based Incident Investigation for Process Safety Leading Metrics

Abstract

Process safety incidents are directly caused by defects of protection layers, and process safety management (PSM) system maintains the soundness of the protection layers. In general, it is said that the weakness in the PSM system is identified from the incident cases, and the performance of the PSM is improve by the PDCA cycle using process safety metrics. However, the PSM business process is comprehended in the plant lifecycle engineering business process, so that even if the weakness of the PSM system is identified, the key engineering business process for the weakness and metrics cannot be recognized, so far. To overcome the above-mentioned problem in process safety metrics, we propose a business process model based process safety incident investigation for process safety metrics.
