General Reference

There is one URL route associated with Risk Based Inspection: rbi. The following table describes the various paths that build on the route, and the elements that you can specify for each.

The following table describes the various paths that are used for the Inspection Plan workflow.

RBI 580

Pipeline Management

The following table lists the System Code Tables that are used by Pipeline Management.

Potential Degradation Mechanisms (PDM) records are used to represent ways in which a component might fail (e.g., mechanical fatigue). These records can be linked to RBI Components and are used to predict and prevent mechanical failure. Each Potential Degradation Mechanisms record that is linked to a Corrosion Loop represents a degradation mechanism, or a way in which the components in that Corrosion Loop might fail.

After a Corrosion Loop is linked to PDMs, as you link RBI Components to the Corrosion Loop, those RBI Components will be linked automatically to all of the Potential Degradation Mechanisms that are linked to the Corrosion Loop. Each PDM that is linked to an RBI Component represents a way in which that component can fail.

Baseline Potential Degradation Mechanisms (PDMs)

GE Digital APM provides several Potential Degradation Mechanisms that are classified as follows, based on the value in the Methodology Type field:

• Qualitative
• Quantitative

All of the PDMs apply to RBI Components. Pressure Relief Devices (PRDs) have a separate set of PDMs, which are different from the ones related to RBI 580 and RBI 581.

The RBI RISK MATRIX BY RBI COMPONENT graph on the Risk Based Inspection Overview page plots the total number of components based on their consequence of failure and probability of failure values. A component is considered while plotting the graph only if the component is linked to an active RBI Criticality Analysis, RBI PRD Criticality Analysis, or RBI Pipeline Analysis.

The color of each cell in the graph is based on the risk category, as described in the following table.

If you pause over a cell on the graph, the probability of failure and consequence of failure values appear, along with the number of components whose consequence of failure and probability of failure match the value in the cell. If you select the cell, the RBI Risk Matrix page appears, displaying the list of components that meet the aforementioned criteria, along with their equipment details, inspection priority, risk category, consequence of failure, and probability of failure values.

You can access a component in the list by selecting the hyperlink in the Component Description column.

RBI Criticality Analysis uses specific states and operations from the baseline State Assignments of GE Digital APM.

In RBI, State Configuration is used in the following families:

• RBI Criticality Analyses
• RBI Recommendations
• Asset Groups

RBI State Assignments and Operations Diagram

When an RBI Criticality Analysis is set to any of the states highlighted in green, the analysis is active. When an RBI Criticality Analysis is set to any of the states highlighted in red, the analysis is inactive.

Additionally, in the diagram, you can see dotted lines and solid lines.

• Dotted lines represent operations that are performed automatically when another RBI Criticality Analysis that is linked to the same RBI Component is set to Risk Completed.
• Solid lines represent operations that you can perform manually.

Details

Initial State: The Created state is the initial state of all new RBI Criticality Analyses.

Reserved States and Operations: The following tables state whether or not the baseline states and operations are reserved. You cannot remove or modify reserved states or operations. You can, however, add your own states and operations to State Assignment.

State Assignment Roles: By default, no State Assignment Roles are assigned to any state in the RBI Criticality Analysis State Assignment.

Analysis Restrictions Based on State

The following table outlines the actions that you can perform on an RBI Criticality Analysis based on its state.

Datasheet Configuration: By default, states and operations will appear in the datasheet when you access an RBI Criticality Analysis in RBI, the Record Manager, or the Bulk Data Form.

If an RBI Criticality Analysis is set to Risk Completed, however, you can modify the value in the Mitigated Risk field in the RBI Degradation Mechanism to which it is linked.

The baseline family-level privileges that exist for these Security Groups are summarized in the following table.

For more information about the State Management process for Inspection Plans, refer to Compliance Management State Management.

The following table provides a list of the baseline family-level privileges that exist for the MI RBI Administrator, MI RBI Analyst, and MI RBI Viewer Security Groups.

The following families are used only to support integration with the Inspection Management module:

• Has Inspection Scope
• Has Time Based Inspection Interval
• Time Based Inspection Interval
• Time Based Inspection Setting

Specifically, certain features of the Time-Based Inspection Settings functionality, which you can use if the Inspection Management license is active, are facilitated by these privileges.

Details

• The Proposed state is the initial state of all Inspection Plans.
• When you change the state of an Inspection Plan from Approved to Modified, an Inspection Plan Revision History record is created.

Reserved States and Operations for Inspection Plans

The following tables indicate whether the baseline states and operations are reserved. You cannot remove or modify reserved states or operations.

The following state changes can be applied to RBI Recommendation.

The diagram below shows the workflow of the baseline State Management process as it applies to RBI Recommendations.

Reserved States and Operations for RBI Recommendations

Example

Consider an organization that has three sites, Site X, Site Y, and Site Z.

Scenario 1: User assigned to only Site X.

This user can access or modify records that are linked to assets only in Site X. However, this user can access all the Potential Degradation Mechanisms in the database.

Scenario 2: User assigned to only Site X and Site Y.

This user can access or modify records that are linked to assets only in Site X or Site Y. However, this user can access all the Potential Degradation Mechanisms in the database.

Scenario 3: Super User

This user can access or modify records that are linked to assets in Site X, Site Y, or Site Z.
