Major process accidents: Their characteristics, assessment, and management of the associated risks

Abstract

Major process accidents continue to occur with the advancement of modern process systems. Major process accidents should not be viewed as Black Swan and can be predicted and prevented. This article investigates the characteristics of process accidents. Based on which, a method for the diagnosis and classification of accidents is proposed. The proposed tool is applied to the Bhopal accident and the swine flu event. The case studies verify the effectiveness and applicability of the proposed tool. To tackle major process accidents, conventional risk assessment, and management approaches are inapplicable without adaption. Enormous research work is needed to develop new generation of methods and tools that enable safer process systems and operations. Knowledge and technological gaps are identified in this perspective. © 2017 American Institute of Chemical Engineers Process Saf Prog 37: 268–275, 2018

Development of safety envelopes and subsea traffic rules for autonomous remotely operated vehicles

“…In such situations, collision risk may increase due to several autonomous vehicles working simultaneously close to the SPS. Yang, (2017) suggests that accidents can be classified based on three dimensions, namely uncertain occurrence, unwanted consequence and uncontrolled development. Collision accidents of AROVs with subsea infrastructure can also be classified as uncertain events, which may have serious unwanted consequence if their development is not controlled.…”
