29: Equipment Reliability Program Design Issue

Node Equipment Reliability Program Design Issue

Definition/Typical Issues

Was there a problem related to the design of the maintenance program? Was the wrong type of maintenance specified for the equipment? Are there problems with the analysis process used to determine the appropriate maintenance requirements? Does the repair activity fail to cover the required scope?

Issues associated with maintenance-related design processes, such as mechanical integrity (MI); reliability-centered maintenance (RCM), risk-based maintenance (RBM); inspection, testing, and preventive maintenance (ITPM), should be coded under this node.

Dual coding under the type of maintenance that was involved (e.g., periodic; event-based; condition-based; fault-finding; corrective; and routine inspection and servicing) is also appropriate.

Note 1: Some organizations use the reliability-centered maintenance process as the primary driver of their equipment reliability program.

Note 2: This section only addressed the design of the reliability program. Implementation of the reliability program is addressed under the other reliability program Cause Types nodes (#33, #37, #42, #47, #51, and #54).

Examples

Example 1

  • A fan system failure resulted in shutting down three paper machines. The failure was the result of a worn-out bearing. The fan system had not been identified as a critical item because no one realized the consequence of its failure.

Example 2

  • There was no reliability program for some of the directional drilling tools. As a result, some of the components failed prematurely.

Example 3

  • Corrective maintenance was assigned to an auger that provided raw materials to a food process. This selection was based on a very low expected failure rate and a quick repair time. Actual experience indicates that the failures took much longer to repair than the analysis team estimated. As a result, planned or predictive maintenance would have been more appropriate.

Typical Recommendations

  • Assign additional resources to equipment with a demonstrated history of problems.
  • Review the frequency of periodic maintenance. If the same activity routinely needs to be performed between scheduled intervals, shorten the periodic maintenance interval.
  • Provide maintenance procedures and training appropriate to the experience level of personnel.
