Description

1.1 General

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 characteristics of 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 in place. Rather, API 585 provides a specific focus on investigating PEI failures as well as near misses or discoveries that are precursors to potential failures that could have significant impact on safety, health, and environment. As such, this RP can add value to process safety incidents/issue investigations by helping to focus specific investigative techniques that would enhance learning and enhance value from PEI incidents.

Significant pressure equipment mechanical integrity incidents are rarely the result of one isolated problem; there are almost always less severe precursors to an equipment failure. These precursors are frequently called near misses or discoveries when they are experienced. Additionally, this document highlights the value in recognizing these precursor occurrences and promotes investigating them to determine the immediate, contributing, and root causes. If these precursor occurrences are uncovered, investigated, and the contributing and root causes are resolved, then major catastrophic failures of pressure equipment could be minimized or prevented.

1.2 Industry Scope

The investigation principles and concepts that are presented in this RP are specifically targeted for application to pressure equipment in the oil, gas, refining and petrochemical industry but could be applied to other equipment and industries at the discretion of the owner-operator.
