This paper describes a holistic, risk-based approach to asset integrity management (AIM). The approach outlined in this paper is referred to as risk-based maintenance. This approach is based on proven risk assessment and reliability analysis methodologies, as well as the need to have appropriate management systems. Combining these tools and management systems provides a holistic approach to managing asset integrity, rather than a seemingly random application of analysis approaches and improvement initiatives. The information in this paper will benefit plant personnel interested in implementing an integrated AIM program or advancing their current AIM program to the next level.

This paper explains a risk-based approach for analyzing process equipment that will help maintenance organizations improve system reliability and optimize maintenance resources. In addition, the approach provides a methodology for organizations to move from a prescriptive or compliance-based maintenance strategy to a risk-based maintenance strategy. The approach outlined is based on proven risk assessment and maintenance analysis tools, such as reliability-centered maintenance. The information in this paper will benefit maintenance professionals interested in optimizing maintenance resources.
