Security Users who were members of the MI RBI Analyst Security Group are now automatically assigned the MI Inspection Plan Approver Role.US360378
To enhance usability when superseding RBI Recommendations, the Completion Comments box has now been added to the RBI Recommendation datasheet.US358589
You can now re-promote an asset from Risk Based Inspection (RBI) to Asset Strategy Manager (ASM) when the asset has been previously promoted to ASM and the resulting actions have been consolidated on the Asset Strategy. To facilitate this enhancement, any consolidated actions on the Asset Strategy will now be unlinked during the promotion of an asset.US353336
To enhance usability and readability, the Process Unit navigation in the RBI 581 Inventory Groups workspace has been updated to display the Functional Location Entity ID instead of the Functional Location ID.US348279
To enhance performance, the queries used in the Risk Based Inspection Overview page, which referenced MI_ENTITIES directly, now reference the Equipment family. To facilitate this enhancement, the following queries have been updated:

You can now implement RBI recommendations that belong to an Inspection Plan in:
  • Asset Strategy Management.
  • Inspection Plan as Inspection Task.
To facilitate this enhancement, a new option, Implement Recommended Actions to Tasks in ASM, has been added to the Global Preferences section of the RBI Admin Preferences page.		US335134
Table 2. Resolved Issues

The following issues that existed in one or more previous versions have been resolved.

DescriptionTracking ID
Previously, for a Criticality RBI Component - Exchanger Bundle, when you copied an RBI Criticality Analysis or created a What-If Analysis from an RBI Criticality Analysis, and then calculated the analysis, the Final Phase and Final Phase Shell Side fields in the related Criticality Consequence Evaluation record were not populated. This issue has been resolved.DE117340
Previously, the value in the Desired Interval field in an Inspection Task was recalculated when the related RBI Recommendation was either deleted or transitioned to the Archived state. This issue has been resolved.DE117062
Previously, when calculating inventory for the Criticality RBI Component – Cylindrical Shell component that contained the value Storage Tank in the Component Type field, an error occurred. This issue has been resolved. Now, the Calculated Inventory field is populated with the correct inventory value.DE100794
Previously, when you attempted to finalize risk of multiple analyses that belonged to multiple Assets or Corrosion Loops, the operation failed completely when there were multiple analyses that belonged to a single component. This issue has been resolved. Now, in this scenario, the analyses that belong to different components are updated to Risk Completed and an error message appears to indicate the number of failed analyses.DE95713
Previously, you could unexpectedly modify unmitigated risk values on Failure Risks with a source of RBI in Asset Strategy Manager (ASM). This issue has been resolved.DE83069

Release Date: July 26, 2019

RBI 580

Release Date: September 27, 2019

Table 4. Enhancements and New Features

The following enhancements and new features have been added.

DescriptionTracking ID
To enhance usability of the Risk Based Inspection (RBI) 580 Data Loader, the following values are now updated in the Interface Log record generated by the data loader:
  • Number of Record Processed: This value is incremented by one for each asset processed by the data loader.
  • Number of Records Rejected: This value is incremented by one for each RBI Criticality Analysis record that encounters an error when processed by the data loader, thus resulting in the record not being created or updated.
  • Number of Records Created: This value is incremented by one for each RBI Criticality Analysis record that is created.
  • Number of Records Updated: This value is incremented by one for each existing RBI Criticality Analysis record that is updated.
US366675
To enhance usability, in the RBI Recommendation, the value in the RBI Recommendation Methodology field has been changed from Criticality Calculator to RBI 580.US353694
To enhance usability when using a UOM conversion set, the values within numeric fields are rounded off according to the type of the numeric field as follows:
Numeric Field TypeNumber of Decimal Places
Pressure, Temperature, Stress, Length, Diameter, Area, Mass, Percent, Age, Cost, Risk2
Thickness, Corrosion Rate, Damage Factor4
Probability of Failure
  • Exponential if value is less than 1
  • 8 decimal places if value is greater than 1
This change is applicable to the fields from the following families:
  • All RBI Component Families
  • RBI Criticality Analysis
  • RBI Consequence Evaluation
  • Criticality Int. Corr. Deg. Mech. Eval.
  • Criticality Ext. Corr. Deg. Mech. Eval.
  • RBI Degradation Mechanisms
US352458
The properties of the following representative fluids that are valid for RBI Criticality Analysis have been updated as per the API 581, 3rd Edition, Addendum 1 specification:
  • C13-16 (Diesel)
  • C17-25 (Gas Oil)
  • C25+ (Resid)
  • C5
  • Chlorine
  • CO
  • EO
  • H2
  • H2O (Water)
  • H2S

Table 5. Resolved Issues

The following issues that existed in one or more previous versions have been resolved.

DescriptionTracking ID
Previously, if the Override Minimum Required Thickness check box was selected for an RBI Criticality Analysis, the value specified in the Specified Tmin box was not considered while calculating the Estimated Half-Life for the Criticality Calculator External Corrosion Degradation Mechanism Evaluation. This issue has been resolved.DE117296
Previously, in the Risk Based Inspection (RBI) 580 Data Loader template, in the Consequence_Evaluation worksheet, the Consequence field contained the default value RBI. Due to this, an error occurred when importing data using the data loader. Now, the default value in the Consequence field has been changed to RBI Consequence.
Note: The error message that appears when importing data using the Risk Based Inspection (RBI) 580 Data Loader that contains an invalid value in the Consequence field has now been updated to include the invalid value and the associated Analysis ID.
DE111087

Previously, in Criticality Calculator RBI Components, the value in the Calculated Inventory field was rounded off to the nearest whole number. Due to this behavior, if the value in the Calculated Inventory field was less than or equal to 0.5, the value was rounded off to 0, which resulted in incorrect calculations. This issue has been resolved. Now, the calculated inventory field displays up to two decimal values.

A similar change has been made to the Inventory field in the Criticality Consequence Evaluation and Criticality Calculator RBI Components.

DE107865
Previously, the Material Grade boxes in the records of the following families contained incorrect values:
  • Piping Stress
  • RBI Components
  • RBI Criticality Analysis

This issue has been resolved. Now, the correct values appear in the Material Grade boxes, as specified in the following table.

Design CodeCode YearMaterial SpecificationMaterial Grade (Incorrect Value)Material Grade (Correct Value)

B31.12014B366/B622A value that begins with NSA value that begins with N/A
B31.32014B366/B622A value that begins with NSA value that begins with N/A
DE96435
Previously, in an RBI Criticality Analysis for a Heat Exchanger Bundle component, the values in the following drop-down list boxes were not translated:
  • Flammable Leak Type
  • Toxic Leak Type
This issue has been resolved.		DE94111
Previously, when creating a What-If Analysis, the Long Term Avg. Corr. Rate, Short Term Avg. Corr. Rate, and Controlling Corrosion Rate fields in the Criticality Calculator Internal Corrosion Degradation Mechanism were not populated with the calculated values from the Thickness Monitoring module. This issue has been resolved.DE86408

Previously, in an RBI 581 Risk Analysis, if you selected a fluid in the Representative Fluid box that did not have a value in any of the following tables, the analysis calculation failed:

  • Personnel Injury Flammable Consequence Equation Constants table (Table 4.9/4.9M, API 581 3rd edition)
  • Component Damage Flammable Consequence Equation Constants table (Table 4.8/4.8M , API 581 3rd edition)
