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.

This article deals with a proposal for a risk analysis option that allows for individual damage mechanism risk calculation. This allows for these individual damage mechanism risks to be compared to a risk target that when reached generates an inspection task with its own due date.
