Developing a Risk-Oriented MOC Program for Effective Resources Allocation and Efficient Management

Management of Change (MOC) is a critical element of Process Safety Management (PSM), yet conventional programs often struggle with high review workloads, limited resources, and slow approval cycles. The prevailing “apply-all” approach can create backlogs, dilute attention to high-risk modifications, and gradually erode confidence in the program’s safety value. This paper proposes a risk-based MOC framework to screen, prioritize, and route changes toward appropriate levels of technical review for petrochemical operations that improves efficiency while maintaining program integrity. The approach introduces an exemption review mechanism and a risk-based classification system to allocate resources toward high-consequence changes, supported by key performance indicators to enable monitoring and continuous improvement. The method is demonstrated through three industrial case studies, and a statistical analysis of historical records quantifies tangible benefits. After implementation, average MOC processing time was reduced by 40%, without compromising process safety. The results illustrate how structured screening, prioritization, and performance tracking can strengthen chemical safety outcomes while enhancing operational efficiency.
