Abstract
For a chemical plant, changes caused by load fluctuation, transition of product markets, revamping of the plant's facilities, et al. are inevitable. Uncontrolled changes caused many accidents or disasters. Thus, management of change (MOC) has been a very important issue in process safety management. In this paper, it is considered that the MOC is divided to two parts: one is an individual change management and the other is a management of them. An individual change management is an instance of engineering over the plant lifecycle (Plant-LCE). A business flow of MOC is expected to be based on a business process model (BPM) of Plant-LCE. An overview for the BPM of Plant-LCE has been proposed. Using an individual change management example, this paper demonstrates that a business flow of the MOC can be described in the overview of the BPM of Plant-LCE. According to the results, importance of sharing information among design, operation and maintenance activities and requirement of supporting system for MOC and Plant-LCE were indicated.
