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.
  By default, this check box is cleared.
• 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.
• 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.
• Enable Release type calculation as per RFI-8388: RBI 581 calculator is currently certified to API 581, 3rd edition, Addendum 1. A suggestion to change the release type calculation was presented in the 2021 API 581 sub-committee spring meeting. Since it will take time for the specification to be updated with the proposed changes, GE Vernova is providing an optional setting to calculate the release type as per the proposed ballot. If you opt for this change, the calculation will not be certified to API 581, 3rd edition, Addendum 1.
• 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.

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.

Applying Evaluation of All Risk Targets

To use this feature, the following fields must be added to the Planning Targets section in the 581 Risk Analysis datasheet:

• Target Inspection Date based on Damage Factor Maximum.
• Target Inspection Date based on Financial Risk.
• Target Inspection Date based on SHE Risk

If the user selects a Driving Risk Target in the analysis while this setting is enabled, their selection is overridden, and the Driving Risk Target is selected based on the Evaluation of All Risk Targets.

Settings in the RBI 581 Admin Options Workspace

The following table provides a list of settings in the RBI 581 Admin Options workspace. For numeric fields, you must enter values only in English standard units.

Example

Suppose you have created an RBI 581 Risk Analysis on 17th March, 2017, which is linked to the 581-Amine Corrosion DM.

The following RBI Criticality Auto-Selection Criteria record is used to assign Inspections to all the DMs that are linked to RBI 581 Thinning and Lining Evaluation (which includes 581-Amine Corrosion).

Suppose the following Inspections appear in the Inspection History for 581-Amine Corrosion:

Among the Inspections in the previous table, the following Inspections are not assigned to 581-Amine Corrosion because they were completed more than 20 years ago:

• Insp-3
• Insp-5

The remaining Inspections are automatically assigned to 581-Amine Corrosion because they satisfy the following conditions:

• They are linked to a DM that belongs to either RBI 581 Thinning and Lining Evaluation or Criticality Int Corr. Deg. Mech. Eval.
• They were completed less than 20 years ago.

Now, suppose you have created an RBI Inspection Auto-Selection Criteria record with the following details:

Suppose you have created another RBI 581 Risk Analysis on 17th March, 2017, which is linked to 581-Amine Corrosion.

In this case, only Insp-1 will be assigned to 581-Amine Corrosion. Although Insp-4 is also linked to 581-Amine Corrosion, it will not be automatically assigned to the DM because the Inspection was completed more than 10 years ago.
