Data Models

Criticality Calculator RBI Component Data Model

The following diagram shows how the families used in a Criticality Calculator RBI Component are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

RBI Corrosion Loop Data Model

The following diagram shows how the families used in an RBI Corrosion Loop are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

RBI Criticality Analysis Data Model

The following diagram shows how the families used to create an RBI Criticality Analysis are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

Pipeline Data Model

The following diagram shows how the families used in RBI Pipeline Management are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

PRD Data Model

The following diagram shows how the families used by Pressure Relief Devices (PRDs) are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

Each Criticality Calculator PRD Component record is linked to other records to further define that PRD. For example, PRD Components records are linked to Potential Degradation Mechanisms records, which define the ways in which the PRD can fail. The following image illustrates the records to which PRD Components records are linked.

In this image, you can see that the Equipment box appears twice. In this image, each Equipment box represents a separate Equipment record. In RBI, you can link a PRD Components record to predecessor Equipment records using the following relationships:

Has RBI Components: Used to identify the PRD itself. In this case, the predecessor Equipment record represents the PRD, and the database would contain two records to represent the same PRD: the Equipment record and the PRD Component.
Asset Is Protected By: Used to identify the equipment that is protected by the PRD. In this case, the predecessor Equipment records represent pieces of equipment that are protected by the PRD.

RBI Data Model

The following diagram shows how the families used in Risk Based Inspection are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

RBI Components

While the data model illustration shows only one RBI Component box, the GE Digital APM RBI data model includes the following RBI Component families:

Criticality Calculator PRD Components
Criticality PRD Component - Relief Valve (used for pressure relief devices only)
Criticality PRD Component - Rupture Disk (used for pressure relief devices only)
Criticality RBI Component - Cylindrical Shell
Criticality RBI Component - Exchanger Bundle
Criticality RBI Component - Exchanger Header
Criticality RBI Component - Exchanger Tube
Criticality RBI Component - Piping
Criticality RBI Component - Tank Bottom
RBI Pipeline Segment

Similarly, while the data model illustration shows only one Criticality Degradation Mech Evaluation box, the GE Digital APM RBI data model includes the following Criticality Degradation Mech Evaluation families:

Criticality Env. Crack. Deg. Mech. Eval.
Criticality Ext. Corr. Deg. Mech. Eval.
Criticality Int. Corr. Deg. Mech. Eval.
Criticality Leak Deg. Mech. Eval.
Criticality Other Damage Mech. Eval.
Criticality Over Pressure Deg. Mech. Eval.
Criticality Third Party Deg. Mech. Eval.

Additionally, the following Criticality Degradation Mech Evaluation families are related only to the PRD Pop Test Checklist family (a subfamily of the Inspection family):

Criticality Leak Deg. Mech. Eval.
Criticality Over Pressure Deg. Mech. Eval.

Each Corrosion Loop can be linked to multiple RBI Components. Each RBI Component can be linked to multiple RBI Analysis records.

Note: Because they are not related to any other families in the RBI data model, the following families are not included in the preceding image: Strategy Logic Case, Strategy Reference Table, Data Mapping Column-Field Pair, Data Mapping Group, Data Mapping Query, RBI Strategy Mapping Configuration, and RBI Strategy Mapping Details. In addition, although GE Digital APM Reference Table families are used by RBI, they are not included in the image.

Example: RBI Process Flow Diagram

RBI allows you to create RBI Analyses that contain calculated data about RBI Components. RBI Criticality Analysis records are linked to RBI Components; therefore, when you create an RBI Component, you must choose the main Equipment record to which it will be linked. Doing so allows some values from the Equipment to be copied to the RBI Component.

You can also link each RBI Component to a Corrosion Loop that represents the corresponding RBI Components.

The following diagram shows a Process Unit that contains a Feed System (green) and an Overhead (OVHD) System (yellow). A Column (i.e., a piece of equipment) is part of the feed system and the OVHD system.

In this case, because the column belongs in two Corrosion Loops, you must divide the column into logical groups of components. Each component represents a single RBI Component, which is defined by a single RBI Component, and each of those RBI Components is linked to the main Equipment representing the column. In addition, each RBI Component can be linked to a Corrosion Loop.

RBI Recommendation Data Model

The following diagram shows how the families used to create an RBI Recommendation are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.
