Risk analysis is essential to the RBI process and involves the systematic use of information to identify the sources of risk and estimate the impact of asset failure. Information can include historical data, theoretical analysis, and informed opinions. Analysis therefore requires a team of people from a range of technical disciplines. The RBI process includes the following stages: • Establish requirements in the context of existing regulations, inspection standards, and practices. • Identify the systems and the assets within them that require integrity management. The criteria and limitations for an RBI approach to inspection planning must be validated because RBI might not be possible or appropriate. • Enter information about the assets, probability of failure, degradation rates, and failure modes in APM in order to manage the data and to assess risk. Analyses are conducted in APM to identify strategies to manage risk and for the development of appropriate inspection plans. • If the analysis results indicate that the asset is not completely fit for service, repairs, modifications, or changes to operating conditions might be recommended. You can use APM’s RBI tools to perform analyses. For example, you can record the results of the analysis team’s analysis directly into APM, using it to perform risk analysis, develop inspection plans, and document the team and the analysis. You can also track the review process by marking analyses as complete or closed. Information that results from the analysis can be presented in several ways.
