Application Settings

In an RBI 581 analysis, users can select a Driving Risk Target which is used to calculate a Target Inspection Date.

When you enable Evaluation of All Risk Targets in the Global Preferences and calculate an RBI 581 analysis, GE Digital APM will determine which risk target to use for a Target Inspection Date based on which risk target is exceeded first. The risk target that is used is also the Driving Risk Target.

Evaluation of All Risk Targets uses the following risk targets to calculate a Target Inspection Date:

• Safety, Health, and Environmental (SHE) Risk
• Financial Risk
• Damage Factor

After evaluation, the Target Inspection Date is used to determine the Driving Risk Target, and the value for Driving Risk Target is set to the risk target that had the most conservative Target Inspection Date.

The RBI 581 Admin Options workspace allows you to define default field values in the following families:

• RBI 581 Risk Analysis
• RBI 581 Consequence Evaluation
• RBI 581 Thinning and Lining Evaluation
• RBI 581 External Damage Evaluation
• RBI 581 External Cracking Damage Evaluation

You can define these settings to:

• All the records of a family (i.e., globally)

  -or-

• Only the records in a specific process unit

A setting for a specific process unit will take precedence over a global setting. For example, if the global setting for Population Density for RBI 581 Consequence Evaluation records was set to 100, and another setting existed specifically for the FCC REACTOR & REGENERATOR Process Unit, which set Population Density to 80, RBI 581 Consequence Evaluation records created for RBI 581 Risk Analyses linked to the FCC REACTOR & REGENERATOR Process Unit would have the Population Density field set to 80.

Each individual setting appears as a node under the RBI581AdminOptions parent node. You will define the settings based on the specific requirements of your organization.

For each node, the following fields are available:

• Target Family: The family of records for which you want to define a default field value.

• Target Field: The field in the target family for which you want to define a default value.

  Tip: The list of values in this field is not alphabetical. To search for a field , enter the name of the field directly into the Target Field field. The list will be filtered.
• Data Type of Field: The data type of the target field. This field is disabled and populated automatically.

• Numeric Field Value: The default value for the target field. This field is enabled only if the value in the Data Type of Field column is Numeric.

• Process Unit: The specific Process Unit to which this setting will apply. This property is enabled only if the Is Global Setting check box is cleared. The list is populated with Functional Locations for which the Is a Process Unit? check box is selected.
• Is Global Setting: When this check box is selected, this setting will apply to all the new records in the target family.
• Character Field Value: The absolute value for the target field. This property is enabled only if the value in the Data Type of Field field is Character.

The RBI 581 ISO-Risk Plot Preferences workspace allows you to modify the default values of the following parameters that are used in the RBI 581 ISO Risk Plot.

The values that you enter must satisfy the following conditions:

• All values must be numeric.
• All values must be greater than 0 because the graph is plotted on a logarithmic scale.
• The lower limits must be less than the upper limits.
• The upper limits for each risk level must be in ascending order. For example, the upper limit for the Low risk level must be less than the upper limit for the Medium risk level.

The Inspection Auto-Selection feature allows you to automatically assign an Inspection to a Degradation Mechanism Evaluation (DME) in RBI 581. By default, this feature is disabled. You can enable the feature by accessing the Inspection Auto-Selection workspace.

For each DME for which you want GE Digital APM to assign Inspections automatically, an RBI Inspection Auto-Selection Criteria record must exist. This record stores the following details:

• The analysis that is performed on the DM
• The DM methodology of the DM
• The equivalent DM methodology
• The years of Inspection History to be considered while linking Inspections

The following table provides a list of baseline RBI Inspection Auto-Selection Criteria records and their field values. You can access these records only after you enable the Inspection Auto-Selection feature.

When you create, duplicate, or apply an RBI 581 Risk Analysis, all the Inspections that meet the criteria specified in the RBI Inspection Auto-Selection Criteria record are assigned to the DME automatically.

The maximum number of Inspections that can be assigned to RBI 581 Cracking Damage Evaluation or RBI 581 External Cracking Damage Evaluation is six. Therefore, among the Inspections that meet the criteria specified in the RBI Inspection Auto-Selection Criteria record, only the latest six Inspections are assigned to the DME. Similarly, the maximum number of Inspections that can be assigned to the 581-Atmospheric Tank Bottom Corrosion DM is one. Therefore, only the latest Inspection (among the ones that meet the criteria) is assigned to the corresponding DME.

Even after you delete an RBI Inspection Auto-Selection Criteria record, Inspections are automatically assigned to a DME. These Inspections, however, are not filtered based on the criteria specified in the record.

This workflow provides the basic, high-level steps for the Inspection Auto-Selection feature. The steps and links in this workflow do not necessarily reference every possible procedure. For more procedures, see the links in the Related Information section.

1. Access the Inspection Auto-Selection workspace.
2. In the upper-right corner of the workspace, select the Inspection Auto-Selection check box.
3. Review the baseline RBI Inspection Auto-Selection Criteria records.
4. In RBI, create an RBI Component, and link it to Potential Degradation Mechanisms (PDMs).

5. Create an RBI 581 Risk Analysis.

   Inspections are automatically assigned to the DMEs based on the criteria in the RBI Inspection Auto-Selection Criteria record.

6. Review the Inspections assigned automatically to the DMEs.

   For RBI 581 Thinning and Lining Evaluation (only if evaluating 581-Atmospheric Tank Bottom Corrosion), RBI 581 Cracking Damage Evaluation, and RBI 581 External Cracking Damage Evaluation, the following fields are populated automatically:

   • Use Combined Confidence
   • Number of Highest Effective Inspections
   • Highest Effective Inspection Level

   For RBI 581 Thinning and Lining Evaluation (if evaluating a Damage Mechanism (DM) other than 581-Atmospheric Tank Bottom Corrosion) and RBI 581 External Damage Evaluation, the following fields are populated automatically:

   • Use Related Inspections
   • Number of A Level Inspections
   • Number of B Level Inspections
   • Number of C Level Inspections
   • Number of D Level Inspections

The Inventory Grouping feature allows you to group RBI Components that belong to a process unit. After you group the components, GE Digital APM calculates the value in the Inventory Group Mass field for the inventory group.

This workflow provides the basic, high-level steps for the Inventory Grouping feature. The steps and links in this workflow do not necessarily reference every possible procedure. For more procedures, see the links in the Related Information section.

1. Access the RBI 581 Inventory Groups workspace.
2. Create an Inventory Group Configuration record for the appropriate process unit. This record stores the details of the name and description of the group, and the process unit that is associated with the group.
3. Link RBI Components to the inventory group.
4. In RBI, access the components that belong to the inventory group.
5. Create an RBI 581 Risk Analysis for each component linked to the inventory group.

6. Access the RBI 581 Consequence Evaluation record associated with each analysis that you have created in the previous step, and then, in the Common section of the datasheet, select the Use Calculated Inventory check box.

   The Inventory Group and Inventory Group Mass fields in the RBI 581 Consequence Evaluation are populated automatically.

   Tip: If the Use Calculated Inventory check box is already selected, clear the check box, and then select it. This will update the inventory group mass value.
