About Global Preferences

About RBI Preferences

The Global Preference settings for Risk Based Inspection contains items for the following settings:

  • 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.
    Tip: For information on the calculation of allowable stress values, refer to the topic.
  • 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 should modify the baseline configuration by clearing this check box.

  • 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.

  • Allow Override of Calculated Unmitigated Risk Values: By default, the unmitigated risk is calculated automatically and displayed on a Degradation Mechanism datasheet, and you cannot modify this value. If, however, you use a custom calculator to calculate unmitigated risk and display it on the Risk Matrix, and you want users to be able to modify the calculated unmitigated risk, then you must select this check box.

  • Consider Half-Life when Determining Inspection Task Interval: This setting determines how the Desired Interval field in Inspection Tasks is populated.

    You must select this check box if:

    • You have created an Asset Corrosion Analysis for an Asset that you analyze in RBI.
    • You want additional values to be considered when determining the desired interval for Inspection Tasks that are created from RBI Recommendations associated with Criticality Calculator Internal Corrosion.

    You can select this check box only if the Thickness Monitoring license is active. By default, this check box is cleared.

  • RBI Overview Graph Preference: This setting allows you to specify which types of analyses should be used to plot risk values on the graphs that appear in the Asset Overview, Component Overview, and Corrosion Loop Overview sections 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.
  • 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.
  • RBI Evergreening Preference: This setting allows you to select the type of analyses that should be used for evergreening.
Important: With the exception of modifying your administrative settings to use new functionality, you should not modify the administrative settings after you have configured them and users have started creating RBI Analyses using those settings.

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:

  1. Add the configured DMs to the Degradation Mechanism Types System Code Table.
  2. Set up PDMs for configured DMs .
  3. Set up Risk Mapping for configured DMs .
  4. Set up RBI Strategy Mapping for configured DMs .
  5. 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.

Half-Life Input to Policies (Appendices G, H, and I) in Strategy Mapping
  • 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.

Action Interval

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.
