Proposal for Individual Damage Mechanism Risk Calculation in API 581
by Michael Hurley, 10/22/2025
Tags: API 581 Mechanical Integrity Process Safety Management Risk Analysis Risk Based Inspection Risk Management Technology
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.

Risk Analysis: Good In, Good Out - A Risk Analyst's View

Tags: Data Collection Data Validation Risk Analysis Technology
An AOC Team Lead reflects on the importance of ensuring your data is accurate and on the impact that having poor data can have on your risk analysis. Having even just one or two erroneous data points can make all the difference in the risk assigned to an asset and the subsequent inappropriate assignment of maintenance and inspection resources. Assigning low risk to a high risk asset because of bad data can result in unexpected and painful consequences.
