Reliability-Centered Maintenance

Reliability Centered Maintenance (RCM) is a maintenance strategy that is used to optimize the maintenance program of a facility so that the productivity of the plant is maintained as cost-effectively as possible.

An RCM strategy starts with identification of the most critical assets that are likely to fail or have large consequences of failure. With this maintenance strategy, possible failure modes and their consequences are identified. Cost-effective maintenance techniques that minimize the possibility of failure can then be determined. The most effective techniques are then adopted to improve the reliability of the facility as a whole.

The NAES Maintenance Services team can help your facility develop an effective RCM strategy.  NAES can help your facility staff identify failure modes, address failure modes by importance, and select the most effective maintenance tasks to address the identified failure modes as cost effectively as possible.

Identify and Define Objectives

The identification process is extensive and typically uses large prioritized datasets to obtain results. NAES identifies Asset Reliability Criteria, prioritizes systems to review, and creates a process for equipment and systems evaluation.

Component Classification

NAES determines and describes all critical component failures, as well as determining potentially critical components to prepare a solution. NAES emphasizes the importance of properly classifying issues in order to best deal with them.

Preventative Selection

NAES determines and analyzes the integrity of both essential and non-essential components, as well as maintaining them through the extent of their use. Deciding how to handle an on site component failure is vital.


NAES has an arsenal of methods to deal with the event of a component failure. If the failure does not have any significant impact the plant can carry on. NAES can also select periodicity in order to run components at a lower rate than usual.
