RBI Components | On-Premises APM

About RBI Components

In Risk Based Inspection, you can divide asset into components whose risk you want to analyze using an RBI 581 Risk Analysis. You can divide a piece of asset into components based on shared degradation mechanisms. Each sub-part of the asset that shares the same degradation mechanisms will belong to the same RBI Component.

In APM, the information related to an RBI component is stored in the following Criticality Calculator RBI Component records:

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 - Pump Compressor Casing
Criticality RBI Component - Tank Bottom
Criticality RBI Pipeline Segment (only if the Pipeline Management license is active)

Heat Exchanger

Consider a Heat Exchanger, which is a piece of asset that contains the following components:

A Cylindrical Shell that makes up the Heat Exchanger Shell section.
A Cylindrical Shell that makes up the Heat Exchanger Channel section.
Any number of small tubes that make up the Heat Exchanger Bundle section.

Each of the components can contain items such as Nozzles, Flanges, or Piping.

In RBI, to analyze the ways in which the exchanger can fail, you must divide the components into logical groups that represent common failure characteristics. Each group of components is a separate component and is represented by a single RBI Component record. Keep in mind that some of these groups are involved in the overhead system, and others are involved in the cooling water system.

For example, you might group the asset's components as follows:

Heat Exchanger Shell: Includes a cylindrical shell, an inlet nozzle, an outlet nozzle, and a head, often referred to as a shell cover. The Shell is part of the Cooling Water System (blue) because the purpose of the shell is to allow water to flow over the tubes and cool the process fluid running through the channel and bundle section of the exchanger.
Heat Exchanger Channel: Includes a cylindrical shell, an inlet nozzle an outlet nozzle and a flat head, often referred to as a dollar plate. The Channel is part of the OVHD System (yellow) because the purpose of the Channel is to funnel the process fluid in to the tubes and allow cooling of the process fluid running through the channel and bundle section of the exchanger.
Heat Exchanger Bundle: Includes tubes, baffles, and a tubesheet. The Bundle is part of the OVHD System (yellow) because the purpose of the bundle is to provide as much surface area as possible for the process fluid in to the tubes and allow cooling of the process fluid running through the bundle section of the exchanger.

If you create an RBI 581 Risk Analysis using this example, your database contains the following records:

Unit / Area (Functional Location record)
Overhead System (Corrosion Loop record)
Cooling Water System (Corrosion Loop record)
Heat Exchanger (Asset record)
Heat Exchanger Shell (Criticality Calculator RBI Components record)
Heat Exchanger Channel (Criticality Calculator RBI Components record)
Heat Exchanger Bundle (Criticality Calculator RBI Components record)

Note: If you have already created Functional Location records to represent the OVHD System and Cooling Water System using the recommended asset hierarchy, you must create additional Corrosion Loop records to represent these same systems. The existing Functional Location records need not be linked to the Corrosion Loop records.

Suggest and Link PDMs to an RBI Component

Before You Begin

Ensure Enable Suggestion of Potential Degradation Mechanism is selected in the Global Preferences Workspace.

About This Task

The APM provides an option to automatically suggest Potential Degradation Mechanisms (PDMs) based on criteria provided in the RBI Component fields. User can then decide whether to link the suggested PDMs to the RBI Component. The suggestions are generated using the RBI Degradation Mechanism Screening Policy. Screening criteria for each PDM is referred from API 581 and API 571. Both the documents are recommended practices and provides guidelines on how to screen components for individual degradation mechanism.

Additional guidelines or good engineering practices defined within these documents are not made mandatory for suggestion purposes. Also, customers might be defining screening criteria based on historical data. Customers requiring these additional guidelines to be included for suggesting PDMs can make suitable changes to the policy. For more information, refer Policies Used to Suggest PDMs topic.

The baseline policy suggests the following Thinning and Lining Damage Mechanisms for the components based on the criteria.

581-Atmospheric Tank Bottom Corrosion
581-Cooling Water Corrosion
581-Soil Side Corrosion
581-Internal Component Lining Damage
581-High Temperature Oxidation
581-High Temperature Sulfidic and Naphthenic Acid
581-Sulfuric Acid Corrosion
581-Hydrofluoric Acid Corrosion
581-Hydrochloric Acid Corrosion

Note:

You can add sub-policies for each degradation mechanism type that you want to automatically suggest in the RBI Degradation Mechanism Screening Policy.

This topic describes how to use the suggested PDMs to link to an RBI Component.

Procedure

Access the RBI Component to which you want to suggest PDMs.
Expand the POTENTIAL DEGRADATION MECHANISMS section.
The list of PDMs linked to the RBI Component appears.
Select Suggest PDMs.

Note: Before performing this step, you must provide all field values that are used as a criteria for suggestion in the associated RBI Component datasheet.
The list of suggested PDMs appears, displaying the reasons for the suggestions.
Note:
- By default, all suggested PDMs will be selected to link to the RBI Component.
- You can deselect the PDMs which you do not want to link to the RBI Component.
- You cannot deselect the PDMs that are already linked to the RBI Component.
- Suggestion basis is set from the return nodes in RBI 581 DM Screening - Thinning and Lining Policy and the numerical values will be in imperial UOM.
Select Link.
The suggested PDMs are linked to the RBI Component.

What To Do Next

Create an RBI 581 Risk Analysis.

Link an RBI Component to a TML Group

Before You Begin

The value in the Source of Calculated Corrosion Rates field in the RBI Component must be Component.
The parent Asset of the RBI Component must not be a Thickness Monitoring Piping Asset.
You must have an active license for the Thickness Monitoring module.

Procedure

Access the RBI Component to which you want to link a TML group.
In the upper-right corner of the workspace, select .
The Manage TML Groups window appears.
Next to the TML Groups that you want to link to the RBI Component, select the check boxes, and then select OK.
The selected TML Groups are linked to the RBI Component.
Note: If the Source of Calculated Corrosion rate is set to Asset or Component on the related component and the related TML asset has more than 1000 TMLs where the related TML Corrosion Analysis has not been calculated, you need to calculate the asset in the Thickness Monitoring module before continuing.

Results

An RBI Component linked to a TML Group inherits the TM corrosion rate values from the TML Group. If the component contains an RBI 581 Thinning and Lining Damage Mechanism Evaluation, the resulting damage factor value will be based on the corrosion rate determined by the value in the Selected Corrosion Rate field.

Apply an RBI Component

About This Task
