RELIABILITY OVERVIEW
Maintenance and Reliability (M&R) practices including condition monitoring are largely governed by the type of assets
being maintained and the associated failure patterns of those assets. Numerous studies have been conducted in both the
Industrial and Aeronautical / Military markets that show the relative frequency or “probability” of failure of equipment. This
data is summarized in Figure 2. What should immediately become apparent is that very few failures are attributable to
“wearing out” or what might be termed an “age-related” failure
pattern.

Those that are age-related are almost all corrosion in seawater applications with a relatively predictable lifecycle.
