RBI Recommendations

About RBI Recommendations

An RBI Recommendation stores information about actions that should be performed to help mitigate the risk associated with a degradation mechanism (DM). Each RBI Recommendation is linked to:

A Degradation Mechanisms record, which defines the type of failure that the recommended action can help mitigate.
An Equipment record, which defines the piece of equipment to which the recommendation applies.
An RBI 581 Risk Analysis record.

Generating Recommendations

GE Digital APM generates RBI Recommendations for:

A single DM
Multiple RBI 581 Risk Analyses linked to a single Asset

You can generate Recommendations based on the policies that are mapped to the RBI Strategies only if:

Inspection Planning suggests a Target Completion Date for an analysis.
The Inspection Will Mitigate field in the RBI 581 Risk Analysis contains the value Yes.
The state of the analysis is Risk Completed.

These Recommendations are Non-recurring.

Recommendations are generated for DMs that are related only to the following DMEs:

RBI 581 Cracking Damage Evaluation
RBI 581 External Cracking Damage Evaluation
RBI 581 External Damage Evaluation
RBI 581 Thinning and Lining Evaluation

You can promote these Recommendations to Asset Strategy Management (ASM), where they are converted to Inspection Tasks.

About Consolidating RBI Recommendations

If two or more RBI Recommendations that are associated with a single RBI Component contain similar information, you can consolidate them into a single RBI Recommendation. The single RBI Recommendation that is created is called the master RBI Recommendation. The two or more RBI Recommendations that you have selected to consolidate are called source RBI Recommendations.

When you consolidate:

The state of the master RBI Recommendation is set to Proposed.
The state of the source RBI Recommendations is changed to Consolidated.
The source RBI Recommendations are linked to the master RBI Recommendation.

You can consolidate RBI Recommendations that are associated with a single RBI Component if they contain the same values in the following fields:

Damage Mechanism
Task Type

These values come from the Inspection Strategy that is linked to the RBI 581 Risk Analysis associated with the RBI Recommendation.

The values in the Damage Mechanism and Task Type fields, in addition to any other fields containing matching values, in the source RBI Recommendations will be used to populate the corresponding fields in the master RBI Recommendation. Additionally, the most conservative (i.e., lowest) value in the Recommended Interval Scope field among the source RBI Recommendations will match the value in the Recommended Interval Scope field in the master RBI Recommendation.

Recommendation Consolidation

Suppose you want to generate RBI Recommendations for RBI Analysis A, RBI Analysis B, and RBI Analysis C, which have the following details:


Field Name	RBI Analysis A	RBI Analysis B	RBI Analysis C
Degradation Mechanism	581-Internal Component Lining Damage	581-Internal Component Lining Damage	581-Austenitic Component Atmospheric Cracking
Inspection Task Type	RBI - MED - EXCH TUBES	RBI - MED - EXCH TUBES	RBI - EXTERNAL - VERY HIGH
Recommended Inspection Interval	90	120	180

In this case, four RBI Recommendations will be created. Since RBI Analysis A and RBI Analysis B are linked to an RBI Degradation Mechanism whose Degradation Mechanism value is 581-Internal Component Lining Damage, and the associated Inspection Strategies contain the same Inspection Task Type value, the RBI Recommendations generated from these records would be consolidated automatically into a single master RBI Recommendation. The state of the consolidated records is set to Consolidated, and the state of the master record is set to Proposed.

The following table lists the four RBI Recommendations that will be created as a result of the automatic RBI Recommendation generation process.


State	Damage Mechanism	Task Type	Recommended Interval Scope
Consolidated	581-Internal Component Lining Damage	RBI - MED - EXCH TUBES	90
Consolidated	581-Internal Component Lining Damage	RBI - MED - EXCH TUBES	120
Proposed	581-Internal Component Lining Damage	RBI - MED - EXCH TUBES	90
Proposed	581-Austenitic Component Atmospheric Cracking	RBI - EXTERNAL - VERY HIGH	180

Notice that two RBI Recommendations are set to Proposed. One of them is the master RBI Recommendation described in this topic, and the other is the RBI Recommendation that was created from the Inspection Strategy that was used for RBI Analysis C.

In the master RBI Recommendation, the value in the Recommended Interval Scope field is set to 90 because this is the most conservative (i.e., lowest) value that exists in the Recommended Inspection Interval field in the source RBI Recommendations.

Scenario B

An associated RBI 581 Risk Analysis:

Whose Criticality Item Type field contains the value Storage Tank Bottom.
That is linked to an RBI Degradation Mechanism whose Degradation Mechanism field contains the value 581-Internal Component Lining Damage.

The policy that will be selected in Scenario A is different from the Policy that will be selected in Scenario B.

The RBI Strategy Mapping Groups also define additional logic that determines the Inspection Strategy that should be used to populate the RBI Recommendation. This logic relies on the following items:

Values stored in the source records that make up the RBI 581 Risk Analysis.
Input nodes that exist in the selected Policy.

Note: RBI Recommendations are generated only if the value in the Inspection Will Mitigate field in the associated RBI 581 Risk Analysis is Yes.

Procedure

Access the Asset Summary workspace for the asset for which you want to generate Recommendations.
In the upper-right corner of the page, select , and then select Generate Recommendations.

The Create Recommendations dialog box appears, asking you to confirm that you want to generate recommendations for the asset.
Select Yes.

A message appears, confirming that you have generated recommendations for all the RBI 581 Risk Analyses linked to all the components in the asset.

You can now utilize the functionality of the Recommended Actions pane .

Tip: For information about additional options available when working with recommendation records, refer to the Action Management section of the documentation.

Generate Recommendations for all Analyses in an Asset Hierarchy Level

About this task

This topic describes how to generate RBI Recommendations for assets linked to a Functional Location in the Asset Hierarchy. You can also:

Create an RBI Recommendation manually.
Generate Recommendations for a single RBI Analysis.
Generate Recommendations for all RBI Analyses linked to a single asset.

Procedure

Access the Risk Based Inspection Overview page for the Asset Hierarchy level for which you want to generate Recommendations.
Select the No Recommendations tab.
The No Recommendations section appears, displaying assets that have at least one component with a Risk Completed analysis with no recommendations.
Select the check boxes next to the assets for which you want to generate recommendations.

Tip: You can generate recommendations for all listed assets in the No Recommendations section by selecting when all check boxes in the first column of the table are cleared. If you select the check box in the first row of the table, recommendations are generated for the analyses that appear in the current page in the No Recommendations section (up to 100 analyses can be displayed in a page). You cannot, however, generate RBI Recommendations for all analyses if the Asset Hierarchy level is set to Home. Generating recommendations will only apply to components that do not have recommendations.
Select .
The Generate Recommendations window appears, asking if you want to consolidate recommendations for each Degradation Mechanism and Task Type.
Tip: If you choose to consolidate recommendations, the recommendations generated during this process will be consolidated with existing recommendations. For more information on consolidating recommendations, consult recommendation consolidation in RBI 580 and RBI 581.
Select Yes.
The Recommendations are generated. The Recommendation Generation window appears, displaying the progress and number of Recommendations generated and consolidated for each asset.
Note: You can close the Recommendation Generation window before it is complete. You can view progress using the Schedule Logs.
Select Close.
Optionally, if you want to view the status of all bulk analyze operations, in the Risk Based Inspection Overview page, select .
The Schedule Logs page appears, displaying a list of all the operations in GE Digital APM that are in progress, along with the percentages of completion. You can also access a list of operations that have been successful or have failed.
