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.

This article deals with a proposal for a risk analysis option that allows for individual damage mechanism risk calculation. This is an example of how it can be applied and how it domonstrates value.

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.

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.
