About RBI Preferences
The Global Preference settings for Risk Based Inspection contain items for the following settings:
- Allow Override of Calculated Unmitigated Risk Values: By default, the unmitigated risk is calculated automatically and displayed on a Degradation Mechanism datasheet which you cannot modify. If you use a custom calculator to calculate unmitigated risk and display it on the Risk Matrix and you want to allow the users to modify the calculated unmitigated risk, then you must select this check box.
- Use Interpolation for Stress Reference Tables: If you select this check box, linear interpolation is used to calculate the allowable stress based on the value in the Design Temperature field. Note: In RBI 581 Risk Analysis, linear interpolation is also used to calculate the flow stress based on the value in the Yield Strength and Tensile Strength fields.
If you do not select this check box, and the value in the Design Temperature field is not an exact match of the metal temperature value available in the stress table, the value in the Allowable Stress is populated based on the following conditions:
- If the design temperature is less than the highest temperature available in the stress table, the next highest temperature value is used to determine the allowable stress value.
- If the design temperature is greater than the highest temperature available in the stress table, the allowable stress value for the highest temperature is populated from the stress table.
Tip: For information on the calculation of allowable stress values, refer to the Allowable Stress Calculation topic. - Enable Suggestion of Potential Degradation Mechanism: If you select this check box, the APM will suggest Potential Degradation Mechanisms (PDMs) for RBI Components based on the data provided at the component level. You can view and link suggested PDMs to their RBI Components.
-
Recommendation Creation Enabled: If you select this check box, you can create RBI Recommendation records in RBI. By default, this check box is selected. If you want to recommend actions and manage mitigated risk in ASM, you must modify the baseline configuration by clearing this check box.Note: When you select this preference, the Use Alternative Inspection Plan Process preference is automatically cleared.
-
Enable Recommendations to be Generated at Created State: Ideally, you must generate Recommendations only for analyses in Risk Completed state. If, however, you want to generate Recommendations for analyses in Created state, you must select this check box.
If you select this check box:
- You can create Recommendations for an analysis in the Created state.
- You cannot create Recommendations for an analysis in the Risk Completed state.
By default, this check box is cleared. You can select it only if the Recommendation Creation Enabled check box is selected.
- Implement Recommended Actions to Tasks in ASM: This setting allows you to specify where the recommended actions are implemented.
- If you select this check box, the RBI sourced Recommended Actions are implemented in Tasks in ASM.
- If you do not select this check box, the RBI sourced Recommended Actions are implemented in Tasks in the Inspection Plan page for the Asset.
Note: This setting is mapped to the Implement Recommended Actions to Tasks in ASM setting in the Inspection Management module. Any change in this setting is updated to the corresponding setting in the Inspection Management module. - Use Alternative Inspection Plan Process: If you select this check box, the APM creates Inspection Plan details instead of creating the RBI recommendations within the Inspection Plan. This setting allows you to finalize the implementation plan as part of this workflow. Note:
- When you select this preference, the Recommendation Creation Enabled preference is cleared automatically.
- After selecting this preference, you must select Update Inspection Plan on pre-existing Inspection Plans to the generate Inspection Plan Details.
-
Consider Half-Life when Determining Inspection Task Interval: This setting determines how the Desired Interval field in ASM action is populated.
The value in the Desired Interval field in ASM action is determined by the minimum values of the following fields:- RBI Recommendation Interval Scope Value
- RBI Half-Life from Criticality Calculator Internal Corrosion
- TM Half-Life of the Asset
You can select this check box only if the Thickness Monitoring license is active. By default, this check box is cleared.
- Enable Inspection Grouping: If you select this check box, the Inspection Grouping workflow is enabled and the Open Inspection Group button appears in the Process Units section of the Risk Based Inspection Overview page.
- Enable Leak Size Based on Degradation Mechanism: If you select this check box, the Leak Size used during the Consequence Evaluation will be based on the related Degradation Mechanisms, not Equipment Type. You must add Degradation Mechanism Leak Size records for each Degradation Mechanism. If you do not provide a value for a Degradation Mechanism, a default value of the minimum of the Diameter and 16 inches will be considered.
If you select this check box, the RBI Criticality Analysis calculation will look up all related Degradation Mechanisms in the Degradation Mechanism Leak Size reference table. The maximum Leak Size for the Degradation Mechanisms will be used in the Criticality Consequence Evaluation calculation.
- Evaluate all RBI 581 Risk Targets: This setting allows you to enable or disable Evaluation of All Risk Targets. When you enable the Evaluation of All Risk Targets feature and calculate an RBI 581 analysis, the Safety Health and Environmental (SHE) Risk, the Financial Risk, and the Damage Factor targets are evaluated to determine a new value in the Target Inspection Date field. The Target Inspection Date field is then used to determine the value in the Driving Risk Target field, and the value for Driving Risk Target field is set to the risk target that has the most conservative Target Inspection Date value. The resulting target and Target Inspection Date are also used to determine mitigation of risk.
- Use Corrosion Rate Adjustment Factors for External Corrosion Damage Mechanisms: As part of API 581, 3rd edition, Addendum 2, Corrosion Rate Adjustment Factors have been updated to only be applied when the Selected Corrosion Rate is Calculated on 581-Ferritic Component Corrosion Under Insulation and 581-Ferritic Component Atmospheric Corrosion Damage Mechanisms. Select this option if you want the factors to be applied regardless of the selected corrosion rate as they were in APM V5.0.0.0.0 and earlier.
- Hide Financial Risk on RBI Risk Card: If you select this check box, financial risk will not be displayed on the risk card in the RBI 581 Risk Analysis workspace if the component type is not Storage Tank Bottom.
About RBI Overview Preferences
The RBI Overview Preference settings for Risk Based Inspection contains the following settings:
- Hide RBI Risk Matrix: This setting determines the visibility of the RBI RiskMatrix on RBI 580 Analyses.
- RBI Analysis Type Preference: This setting determines the preferred RBI Analysis methodology. This preference is used to filter analyses displayed in the RBI Asset Overview, RBI Corrosion Loop Overview, the Evergreening workspace and the Export workspace.
- RBI Overview Graph Preference: This allows you to specify which type of analyses to be used to plot risk values on the graphs that appear in the Component Overview section in RBI.
You can select one of the following values in the drop-down list box:
- RBI 580: If you select this value, the risk values of only RBI Criticality Analyses, RBI PRD Criticality Analyses, and RBI Pipeline Analyses are plotted.
- RBI 581: If you select this value, the risk values of only RBI 581 Risk Analyses are plotted.
- 580 and 581: If you select this value, the risk values of all types of analyses in RBI are plotted.
- RBI Overview Table Preference: This setting allows you to add or remove the columns displayed in the Component Overview page. This section contains two tables:
- RBI 580 Selected Columns: Displays the RBI 580 columns that are selected to display. You can select any field available in the RBI Criticality Analysis family. By default, the Driving Inspection Priority (Unmitigated Risk) and Risk Category columns are selected.Note: You can see this table only if you have an active Risk Based Inspection license.
- RBI 581 Selected Columns: Displays the RBI 581 columns that are selected to display. You can select any field available in the RBI 581 Risk Analysis family. By default, the Total SHE Risk -RBI Date column is selected.Note: You can see this table only if you have an active RBI 581 license.
- RBI 580 Selected Columns: Displays the RBI 580 columns that are selected to display. You can select any field available in the RBI Criticality Analysis family. By default, the Driving Inspection Priority (Unmitigated Risk) and Risk Category columns are selected.

Procedure
About Configuring Multiple Degradation Mechanisms (DMs) for a Single RBI Criticality Analysis
The baseline RBI workflow uses one driving Internal Corrosion and one driving External Corrosion DM per RBI Criticality Analysis. The driving DM that is used for an RBI Criticality Analysis has the highest corrosion rate.
Your organization, however, may choose to rename Internal Corrosion and External Corrosion DMs or to add multiple Internal Corrosion DMs for a single RBI Criticality Analysis.
Prior to using multiple Internal Corrosion DMs or a configured External Corrosion DM, you must complete the following steps:
- Add the configured DMs to the Degradation Mechanism Types System Code Table.
- Set up PDMs for configured DMs.
- Set up Risk Mapping for configured DMs.
- Set up RBI Strategy Mapping for configured DMs.
- Update the Non-Intrusive Requirement Met query.
Expected Recommendation Behavior
When you use configured External Corrosion and/or multiple Internal Corrosion DMs for a single RBI Criticality Analysis, the expected behavior for some of the fields differs from that of an analysis driven by a baseline DMs. The following baseline field behaviors are affected by the use of configured DMs:
Recommended Interval Value for Recommendations- For a Recommendation generated for an Internal Corrosion DM, the Recommended Interval value is mapped from the corresponding Internal Corrosion DME.
- For a Recommendation generated for an External Corrosion DM, the Recommended Interval value is:
- Mapped from the corresponding External Corrosion DME when Appendix F is used to generate the Recommendation.
- Mapped from the most conservative Half-Life from all Internal Corrosion DMEs linked to the Analysis when Appendices H or I are used to generate the recommendation.
-
For a Recommendation generated for a Cracking DM, the Recommended Interval is mapped from the most conservative Half-Life from all Internal Corrosion DMEs linked to the Analysis.
- For a Recommendation generated for an Internal Corrosion DM, the Half-Life policy input value is mapped from the corresponding Internal Corrosion DME.
-
For a Recommendation generated for a Cracking or External DM, the Half-Life policy input value is mapped from the most conservative Half-Life from all Internal Corrosion DMEs linked to the Analysis.
When you select the Consider the Half-Life when Determining Inspection Task Interval field on the RBI Global Preferences workspace, the interval for the action associated with an Internal DM is set to the Half Life of the correspond Internal Corrosion DME unless the Recommendation Interval is less than the Half-Life value.
