Risk Based Inspection supports the following methodologies.
The RBI 581 Methodology
After you conduct a RBI 581 Risk Analysis, if it is possible to mitigate risk at the component, RBI 581 will recommend inspection tasks that will, for a specified period, keep the projected risk below the thresholds. These thresholds are called Risk Targets. They are determined by your organization. If risk cannot be mitigated (i.e., inspections would not bring risk below the Risk Target values), the Risk Summary of the analysis provides a synopsis which will help determine the next course of action.
Based on the analysis results, if risk is mitigated, you can generate recommendations. This is to capture recommended actions and create non-recurring inspection tasks that must be completed in order to mitigate risk over the plan period.
The RBI 580 Methodology
After you conduct an RBI Criticality Analysis, if the risk values are unacceptable, you can analyze hypothetical scenarios using What If Analyses and Future Risk Analyses to see how additional actions or factors might affect the risk. For example, you might create a What If Analysis to see what the risk level would be if you changed the operating pressure. Or, you might create a Future Risk Analysis to see what the risk level might be in five years.
Based on the analysis results, you can create RBI Recommendations to capture recommended actions that might mitigate the risk associated with a component. You can then create Tasks or SAP Notifications from the RBI Recommendations to track the progress and ensure that the recommended actions are implemented.
After the recommended actions are implemented, you can conduct another RBI Criticality Analysis to determine if the new operating procedures or environment have actually reduced the risk.
