RBI Policies

An RBI Policy allows you to develop and execute strategies based on historical data and dynamic data, which is obtained by monitoring conditions in real time. The policies used in RBI are categorized as follows:

These policies appear in the Module Workflow Policies section of the Policy Designer Overview page.

RBI Strategy Mapping Configuration

The RBI Strategy Mapping Configuration family defines the Policy records that are used to generate RBI Recommendation records automatically from RBI Analyses. The information in the table reflects the baseline state and behavior of fields that exist in the RBI Strategy Mapping Configuration family.

RBI Strategy Mapping Configuration Details


Field	Data Type	Description	Behavior and Usage
Degradation Mechanism	Character	The value in the Degradation Mechanism field linked to the RBI Analysis for which you are generating RBI Recommendations.	This field is populated by default in each RBI Strategy Mapping Configuration that is delivered to the baseline APM database.
Policy Name	Character	The Record ID of the Policy used to generate an RBI Recommendation.	This field is populated by default in each RBI Strategy Mapping Configuration that is delivered to the baseline APM database.

RBI Strategy Mapping Details define the Policy Input nodes that are used to generate RBI Recommendation records automatically from RBI Analyses. The information in the table reflects the baseline state and behavior of fields in the RBI Strategy Mapping Details family.

Criteria Used to Generate RBI Recommendations from RBI Analyses

The following table lists the criteria used by RBI Strategy Mapping Groups to determine the Policy that APM uses to select the Inspection Strategy. The selected Inspection Strategy is then used to populate the RBI Recommendation.

Note: The APM RBI Best Practice assumes that you will use the RBI Strategy Mapping Configurations, RBI Strategy Mapping Details, and policy queries that GE Vernova provides, and that you will not modify them.

The following table provides a list of Policies that are used to generate RBI Recommendations.

Policies Used to Suggest PDMs

The RBI Degradation Mechanism Screening Policy is used to screen the PDMs for the RBI Component. The policy contains a sub-policy, such as RBI 581 DM Screening - Thinning and Lining, which 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

You can add sub-policies for all other Damage Mechanism types that you want to screen.

You must be a member of the MI Policy Designer Security Groups to modify the design of a policy.

You must be a member of the MI Policy Viewer Security Groups to view a policy.

RBI 581 DM Screening - Thinning and Lining policy follows the below guidelines. If there are adequate measures to eliminate or minimize corrosion you can deselect the suggested PDMs from linking.


Suggested Thinning DM	Available field in RBI Component	Screening Criteria	Notes
581-High Temperature Sulfidic and Naphthenic Acid	Operating Temperature	Operating temperature shall be greater than 400 degrees Fahrenheit	Majority of all Base Materials are suspected. Thus, system is not checking Base Material field.
581-High Temperature Sulfidic and Naphthenic Acid	Sulphur Concentration	Process Fluid shall contain sulphur compounds
581-High Temperature Oxidation	Operating Temperature	Operating temperature shall be greater than 900 degrees Fahrenheit
581-High Temperature Oxidation	Is Air or Oxident Present?	Air or Oxidant shall be present
581-Hydrochloric Acid Corrosion	Process Fluid	The representative fluid shall be HCL
	Free Water	Presence of Water shall be detected
	pH of Water	Reported pH shall less than 7
581-Hydrofluoric Acid Corrosion	Process Fluid	The representative fluid shall be HF
581-Sulfuric Acid Corrosion	Process Fluid	The representative fluid shall be H₂SO₄ (Sulfuric Acid)
581-Cooling Water Corrosion	Cooling System Type	Presence of a Cooling water system	Defining a Cooling system Type in RBI component shall screen the component for soil side corrosion.
581-Soil Side Corrosion	Soil Type 581	Equipment is partially or fully exposed to soil.	Defining a Soil Type in RBI component shall screen the component for soil side corrosion.
581-Internal Component Lining Damage	Liner Present	A liner provided to protect the base material shall be present.	NA
581-Atmospheric Tank Bottom Corrosion	Component Type	Component Type shall be Tank Bottom	Tank Bottom is suspected since it is expected to be degraded from either process side or soil side.
