This document presents a practical framework for implementing Risk-Based Inspection (RBI) and Mechanical Integrity (MI) programs for U.S. oil and gas production, gathering, and midstream facilities. It outlines lifecycle asset management practices aligned with API 510/570/653, API 580/581, PHMSA pipeline safety rules, and OSHA PSM to prevent loss of containment, detect degradation early, and maintain safe, reliable operations.by Michael Hurley, 3/3/2026

In the refining industry, "culture" is often only analyzed after a failure occurs. However, a robust culture is defined by observable, repeatable behaviors and daily decisions made under pressure. This article outlines the seven practical attributes of high-performing refining organizations and demonstrates how alignment between leadership values and technical integrity creates a safer, more profitable operation.

Investigations by the CSB and industry standards like API RP 754 reveal that the majority of loss-of-containment events are preventable through disciplined execution. While degradation mechanisms are often well understood and corrective actions identified, disasters frequently occur because repairs are delayed or inspections are deferred. This post explores how organizational accountability and robust governance can prevent these systemic breakdowns in PSM execution.

Mechanical Integrity (MI) is the crucial foundation of Process Safety Management (PSM). Major accidents overwhelmingly result from equipment failures like ruptured vessels or corroded piping. This post details eight essential reasons why a robust MI program is vital, including preventing loss of containment , ensuring safeguards function as designed , and meeting mandatory OSHA and EPA compliance.

Public data suggests U.S. refinery fires and explosions have increased significantly since 2018, with some analyses showing a tripling of incidents. However, industry process safety metrics indicate improvement. This article explores the evidence, why the datasets conflict, and the start of the upward trend.

Despite OSHA's 1992 Process Safety Management (PSM) standard, refinery and chemical plant fires continue to make headlines. This post breaks down the seven systemic reasons why these incidents persist. We explore how mere compliance, aging infrastructure, weak safety culture, and reactive risk management prevent the elimination of catastrophic risks.

Discover how transitioning to a Risk-Based Inspection (RBI) approach can deliver real value and significant cost savings over traditional time/condition-based Mechanical Integrity (MI) programs. We use a simple 100-vessel example to show a potential $645,000 savings per inspection cycle and discuss how RBI accelerates compliance and prioritizes safety-critical tasks.

In 2021, I published a proposed change to the API 581 PoF calculation. While I believe API 581 is solid as a recommended practice, I believe that inspection planning can be further optimized and fine-tuned to adapt to organizational needs. Since then, the original article has prompted a variety of comments and questions and so I have rewritten the original article for, hopefully, a little more clarity, and I have consolidated the top questions along with my comments.

When organizations face budget cuts, they may postpone projects, but certain risks are too critical to delay. This post highlights three such Risk-Based Inspection (RBI) risks that demand immediate attention: high-risk equipment, Corrosion Under Insulation (CUI), and overdue critical inspections. Acting now can safeguard people, assets, and the bottom line from costly failures.

This article deals with the dysfunctionality found in many refineries, chemical plants, and other production facilities. This can lead a facility to not reaching its value and reliability goals. One of the main reasons for this dysfunctionality is facility departments not using a common asset management work process.
