Reliability-Centered Maintenance
Appropriate maintenance of physical assets is a critical basis for meeting the production, health,
safety, and environmental performance goals of a plant in a cost-effective way.
The reliability-centered maintenance approach (RCM, and the extended RCM2) to establishing maintenance requirements is one that is based on systematic consideration of
the potential failure modes of equipment,
the consequences of each failure mode (such as extent of production interruption, repair cost, safety implication, environmental impact, and regulatory consequence),
and the likelihood of each failure mode.
These considerations underlie the identification of equipment monitoring requirements,
and help establish the need for, the type of, and the frequencies of preventive maintenance and replacement activities.
We have provided strong, knowledgeable support to our clients in establishing RCM programs
through:
| |
 |
initial analyses to identify asset failure modes, consequences, and likelihoods
|
|
| |
 |
establishment of equipment performance and reliability tolerance criteria
|
 |
establishment of monitoring and maintenance requirements and frequencies
|
 |
preparation of maintenance procedures
|
 |
development of systems and supporting software for asset performance data collection and analysis
|
 |
root cause analysis supporting reliability data development.
|
We have also contributed to the literature of RCM and developed several supporting software items:
| |
 |
ePHA which incorporates Failure Modes and Effects Analysis (FMEA) methods
|
 |
eFTA for fault tree modeling
|
 |
eMargin for economics-based reliability allocation in more complex plants.
