Link Potential Degradation Mechanisms (PDMs) to an RBI Component

If the RBI Component is linked to a Corrosion Loop, then all the PDMs linked to the Corrosion Loop are also linked to the Component. You can, however, link additional PDMs to the Component.

This topic describes how to link one or more PDMs to an RBI Component. You cannot create PDMs; you can only link them. Therefore, a PDM must already exist to be linked to an RBI Component.

Steps

Access the RBI Component to which you want to link PDMs.
Select the Potential Degradation Mechanisms tab.

The Potential Degradation Mechanisms section appears, displaying a list of PDMs linked to the RBI Component.
Select Add PDM.

A list of PDMs appears, displaying the methodology type of each PDM.

Tip: If you select the link that corresponds to a PDM, the PDM record appears in Record Explorer on a new page.
Next to each PDM that you want to link to the RBI Component, select the check box, and then select OK.

Note: PDMs that can be used with an RBI 581 Risk Analysis contain a 581 prefix (e.g., 581-Amine Cracking).

The selected PDMs are linked to the RBI Component.
