Maintenance subsections.

RBI specific data section of the **Settings** Menu includes three subitems: S-RBI Specific Data, RBI 581 Specific Data, and the Degradation Mechanisms. The Degradation Mechanisms is needed for both S-RBI and RBI 581. RBI 581 Specific Data is only visible when RBI 581 is enabled for your site.

## S-RBI Specific Data

The S-RBI include tables for maintaining RBI related information, such as Barrier Types, Degradation Mechanisms, Inspection Techniques and Measurement Groups (for a measurement unit).

### Barrier Types CMF

Here all available Barrier Types for the Corrosion Loop's Degradation Management section are defined. Any of these can be added to a Corrosion Loop (CL).

### Barrier Types DM

Here the Common barrier types per Degradation Mechanism (DM) are defined. The Common barrier types will be shown on the applicable DM card in the CL’s Degradation Management section.

Adding a new IOW Variable.

### Suggested IOW Variable

Here the suggested IOWs per Barrier Type are defined. When a Barrier Type has been added in the Degradation Management section of the CL, the applicable IOW variables will then be suggested in the IOW section of the CL.

![Graphical user interface, application  Description automatically generated](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/rbi-specific-data-image-q56u3xex.png?sv=2026-02-06&spr=https&st=2026-10-28T12%3A43%3A17Z&se=2026-10-28T13%3A43%3A17Z&sr=c&sp=r&sig=b6s6eteScjTesgHsVwQ2%2Bl0%2BrIMKA2so4UCcSS%2BkpsA%3D)

Suggested IOWs show in the IOW section of the CL.

### Pi Server - Site

Here the Pi Server per site is defined. This is required to gather the IOW data, for the exceedance calculations.

### Product

Here the Products and their parameters can be viewed/edited/added/deleted. These Products can be selected in the RBI Specs. Once the "SRBI-Product" is chosen, the remainder of the available data fields will be automatically populated.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/rbi-specific-data-image-5axhninz.png?sv=2026-02-06&spr=https&st=2026-10-28T12%3A43%3A17Z&se=2026-10-28T13%3A43%3A17Z&sr=c&sp=r&sig=b6s6eteScjTesgHsVwQ2%2Bl0%2BrIMKA2so4UCcSS%2BkpsA%3D)

Select the Product on the Operating Conditions section.

This is also used to display the relevant product operating conditions in the RBI Analysis **Operating Conditions** tab. See [Step 4- Determine the most credible failure scenario](/docs/software-step-4#review-the-operating-conditions).

## RBI 581 Specific Data

RBI 581 Specific Data is only visible when RBI 581 is enabled for your site. Here data related to the [RBI 581](/v414/docs/api-581-overview) Calculations are captured:

- Representative Fluid - You need to select a Representative Fluid Material on the [CoF](/v414/docs/rbi-581-consequence-of-failure) tab. Based on this selection, the corresponding Representative Fluid is retrieved from here, and the associated data is used in the CoF calculation.
- Release Hole Size And Areas
- Detection Isolation
- Toxic Release Consequence
- Equipment GFF Costs Outage - The Mapped column displays the Equipment Group, Component Type, and Diameter to which each row is mapped. This mapping can be updated in the table on the right.
- Inspection Effectiveness
- Criticality and Probability Default Values. This is where you select the Risk Calculation Method and Target criteria - see [RBI 581 Risk](/v414/docs/rbi-581-risk-matrix).

### Criticality and Probability Default Values

These values are editable. The first set of values are used to calculate the Management Systems Factor (FMS). See [RBI 581 FMS (Management Systems Factor)](/v414/docs/setting-up-for-rbi-581-analyses#setting-up-the-management-systems-factor-fms).

Next Risk Calculation Method and Risk Matrix Balanced can be used to select the desired Risk Matrix for your site. To learn more see [RBI 581 Risk](/v414/docs/setting-up-for-rbi-581-analyses#specifying-which-risk-calculation-method-to-use).

Also the Risk Target Criteria are specified here. To learn more see [RBI 581 Risk](/v414/docs/setting-up-for-rbi-581-analyses#specifying-the-risk-target-criteria).

## Degradation Mechanisms

Here the Degradation Mechanisms (DM) can be viewed/edited/added/deleted. Per DM the table shows things like:

- The Type of DM ("Age-Related", "Non-Age-Related", or "Strategy Based").
- The Inspection Effectiveness (IE) determines the type of Inspection Effectiveness used in [RBI 581](/v414/docs/rbi-581-probability-of-failure). IE can only be mapped to the parent DM, for example, THINNING: CORROSION, EROSION, etc., which means all child DMs automatically inherit the IE from the parent.
- The RBI581 Damage Factor displays the name of the RBI 581 calculation mapped to each IMS Degradation Mechanism. If a Degradation Mechanism is mapped (i.e., has a value in the RBI581 Damage Factor column), this indicates that an RBI 581 calculation exists for it in IMS.
- Whether the DM Is Internal or not.
- Mapped Tank DMs are also shown (these apply in [Tank RBI assessments](https://ims-handbook.cenosco.com/v414/docs/tanks)).
- Etc.

On each DM, attachments can be added. The list can also be filtered and Exported.

Any of these DMs can be added to a Corrosion Loop, in the Degradation Management section. When done, these DMs can then be assigned to any of the Components that are linked to that CL. Subsequently an RBI analysis can then take place per Component-DM combination. To learn more about DMs see [Degradation Mechanisms - Classification and Definition](/v414/docs/degradation-classification-theory) and [Step 2 Identify Threats and Barriers (Define the CL)](/v414/docs/step-2-identify-threats-and-barriers-define-the-cl-1).
