Adding Barriers to RBI Failure Modes

A barrier is a means of slowing or mitigating asset degradation. For example, coating, lining, and chemical treatment are used to slow corrosion in metal piping.
When recording failure modes in an analysis, the team can add barriers to the failure mode either by selecting barriers assigned to the asset or by creating them for the asset. If the current failure mode was added from the damage mechanisms library, you can also drag and drop barriers from the library to the failure mode.
Note: For barriers to be added to assets, the asset type must be set to allow barriers to be defined for it.
Tip: In the analysis’ failure mode settings, select the Barriers tab to set the default behavior for adding barriers to assets from the failure mode. You can specify that barriers are added to the failure mode asset or to the primary analysis asset.
Tip: You can also use the Work With list to view, add, and delete barriers. See Working with Barriers on RBI Failure Modes.
This topic explains how:
•
To Add Barriers to a Failure Mode
•
To Add Barriers from a Library Failure Mode

To Add Barriers to a Failure Mode

1.
Open the failure mode’s Maintenance Action Plan window.
2.
Make sure that editing is enabled.
3.
Select the Degradation view, Barriers tab. For example:
This tab lists any the barriers on the failure mode’s asset. You can select the barriers that apply to the failure mode.
4.
To add a new barrier to the asset, click New. The Failure Barrier Properties dialog appears.
5.
The Asset boxes show either the failure mode’s asset or the primary asset on the analysis. To create the barrier for another asset, click the browse icon ().
6.
Provide information about the barrier:
Setting Name
Description
Barrier type
The type of barrier, for example, metallic liner or cladding.
Effectiveness
Barrier effectiveness is defined as one of:
•
Primary barrier – The barrier is most effective in controlling deterioration.
•
Secondary barrier – The barrier does not control deterioration completely or is effective for a limited time. Typically, two or more secondary barriers are assigned to an asset.
7.
On the Risk tab, select a risk-ranking value, for example, “High”, “Medium”, or “Low”. A barrier’s risk ranking identifies the relative severity of the problem that the barrier is meant to prevent or mitigate. Provide a reason for selecting the risk level in the text box below.
8.
Select the Compliance tab and add the following information:
Setting Name
Description
Compliance status
Barrier compliance statuses are used to indicate the degree to which the barrier is in place. The compliance status settings in APM are typically represented as amber (limited compliance), green (fully compliant) and red (not compliant).
Compliance reason
The compliance status reason indicates why the barrier is or is not compliant. Examples are historical proof, inspection history, and coating not applied.
Monitoring note
Information about how the barrier’s effectiveness is monitored.
9.
Select the Monitoring Indicators tab. On this tab, you can select or create indicators to be used to check the effectiveness of the barrier.
10.
Select the Description tab to add more information about the barrier.
Tip: The Failure Modes tab lists the failure modes that reference the barrier. The History tab provides an audit history of the actions performed on the barrier record in APM.
11.
Click OK. The Failure Barrier Properties dialog closes and the barrier is added to the asset and listed on the Barriers tab.

To Add Barriers from a Library Failure Mode

1.
Open the failure mode that was added to the analysis from the Damage Mechanisms Library. The Maintenance Action Plan window appears.
2.
Make sure that editing is enabled.
3.
Select the Degradation view, Barriers tab. This tab lists the barriers on the asset on the left and the library barriers on the right. For example:
4.
To add a barrier from the library, select it in the right-hand table and drag it to the left-hand table. The barrier is added to the right-hand table and selected. It is also added to the asset.
