RBI Components

About RBI Components

In Risk Based Inspection, you can divide equipment into components whose risk you want to analyze using an RBI 581 Risk Analysis. You can divide a piece of equipment 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 GE Digital 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 equipment 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 equipment'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 (Equipment 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.

Access an RBI Component

Procedure

  1. Access the Asset Summary workspace for the asset that contains the RBI Component that you want to access.

    -or-

    Access the Corrosion Loop that contains the RBI Component that you want to access.

  2. Below the graph, select the link corresponding to the component that you want to access.

    -or-

    In the left pane, select the component that you want to access.

    The workspace for the selected component appears, displaying the Component Overview section.

  3. Select the Component Details tab.

    The Component Details section appears, displaying the datasheet of the Component.

    Note: If needed, modify values in the available fields, and then select to save your changes.

Create an RBI Component

About this task

This topic describes how to create a new RBI Component and link it to an Asset or a Corrosion Loop. You can also link an existing RBI Component to an Asset or a Corrosion Loop.

Procedure

  1. Access the Asset Summary workspace of the asset in which you want to create an RBI Component.

    -or-

    Access the Corrosion Loop in which you want to create an RBI Component.

  2. In the left pane, select , and then select Create New Component.

    The Create New RBI Component window appears.

  3. Enter values in the following fields:
    • Asset: This field is automatically populated with the asset for which you are creating an RBI Component.
    • Component Family: Select the component family for the Component that you want to create.
    • Component Type: Select the component type for the RBI Component that you want to create.
  4. Select Create.

    A new RBI Component is created, and is automatically linked to the selected Asset and the Corrosion Loop. The Component Details section appears, displaying the component datasheet.

  5. Enter values in the available fields.
  6. In the RBI-581 section of the datasheet, enter values in the available fields.
  7. In the upper-right corner of the datasheet, select .

    The changes made to the RBI Component are saved.

What to do next

Access the Inventory Group of a Component

About this task

You can also access all the inventory groups in a process unit.

Procedure

  1. Access the Component that is linked to the inventory group.
  2. In the upper-right corner of the page, select , and then select Inventory Group.

    The RBI 581 Inventory Groups workspace appears on a new page, displaying the following information:

    • If the component is linked to an inventory group, then the Inventory Group Configuration datasheet for the inventory group associated with the component appears.

      Tip: If you want to access a list of components linked to the inventory group, select the Linked Components tab.

    • If the component is not linked to an inventory group, then the Process Units with Inventory Groups graphs appears. A list of process units appear in the left section in the workspace.

      Tip: If you are a member of the RBI Admin Security Group, you can create an Inventory Group Configuration record in the RBI 581 Inventory Groups workspace.

Apply an RBI Component

About this task

When you apply an RBI Component, you make a copy of the original record. The applied RBI Component is not automatically linked to the original RBI Component's Corrosion Loop. Instead, the applied RBI Component can be linked to the same or a different asset and then to a Corrosion Loop.

Procedure

  1. Access the RBI Component that you want to apply.
  2. In the upper-right corner of the page, select .

    The Hierarchy Finder window appears.

  3. Navigate through the Hierarchy Finder to select the asset to which you want to apply the RBI Component.
  4. Select OK.

    The RBI Component is applied to the selected asset.

What to do next

    Access the Corrosion Loop that is linked to the RBI Component that you want to delete.

  2. Next to the Component what you want to delete, select the check box next, and then select .

    A message appears, asking you to confirm that you want to delete the selected RBI Component.

  3. Select Yes.

    The RBI Component is deleted, and all links to existing related entities are removed.
