About Potential Degradation Mechanisms (PDM)

Potential Degradation Mechanisms (PDM) records are used to represent ways in which a component might fail (e.g., mechanical fatigue). These records can be linked to RBI Components and are used to predict and prevent mechanical failure. Each Potential Degradation Mechanisms record that is linked to a Corrosion Loop represents a degradation mechanism, or a way in which the components in that Corrosion Loop might fail.

After a Corrosion Loop is linked to PDMs, as you link RBI Components to the Corrosion Loop, those RBI Components will be linked automatically to all of the Potential Degradation Mechanisms that are linked to the Corrosion Loop. Each PDM that is linked to an RBI Component represents a way in which that component can fail.

Baseline Potential Degradation Mechanisms (PDMs)Closed

GE Digital APM provides several Potential Degradation Mechanisms that are classified as follows, based on the value in the Methodology Type field:

All of the PDMs apply to RBI Components. Pressure Relief Devices (PRDs) have a separate set of PDMs, which are different from the ones related to RBI 580 and RBI 581.

GE Digital APM provides the following Qualitative Potential Degradation Mechanisms:
