From an asset management perspective, it is necessary to understand the root cause of plant failure in order to establish effective condition monitoring and asset management strategies. Insurance companies, and other organizations, have conducted considerable research into the reasons for plant failure. Not surprisingly, many plant studies into mechanical and electrical equipment failures reveal similar system failure root causes.
The data in Figure 17 has been taken from a number of industries of varying ages and capacity factors. In general, the data indicates that human intervention in the machine in the form of lubrication quality, and contamination control, is the primary factor in the longevity of a mechanical plant. The data also indicates that lubrication analysis is the prime control method for determining mechanical plant condition, particularly in a rotating mechanical plant.
