The purpose of this document is to provide owner-operators with practices for developing, implementing, sustaining, and enhancing an investigation program for pressure equipment integrity (PEI) incidents. This recommended practice (RP) describes how an effective investigation could be structured so organizations can learn from PEI failures, near misses, or discoveries. This RP is not intended to define or supplement criteria for compliance with regulatory requirements for which companies already have defined investigation processes. Instead, API 585 focuses on investigating PEI failures, near misses, or discoveries that are precursors to potential failures that could have a significant impact on safety, health, and the environment. As such, this RP can add value to process safety incident investigations by helping to focus specific investigative techniques that would enhance learning and value from PEI incidents. See more
