Enbridge’s decision to formalize a Process Hazard Analysis (PHA) program has taken the organization through a journey from an informal/ad hoc practice to a rigorous, standardized, best-practice-based process with selected methodologies and tools being applied to all capital and operation projects in the company.

This paper begins with a description of past hazard practices in the oil and gas pipeline industry in relation to the application of a hazard analysis. The oil and gas pipeline industry is governed by PHMSA, NEB, TSB, and provincial OHSA regulations, but is not regulated by OSHA or EPA RMP. Using this regulatory framework as a reference, a standard corporate PHA at Enbridge was developed and implemented. The paper describes the process, the methodologies, and the associated templates and tools. The implementation strategy is also discussed, including training deployment and communication plans. Finally, a road map for continuous improvement describes how to make the process sustainable by closing the current process gaps in relation to best practices and achieving a maturity stage of execution.
