Abstract: 

Maintenance of plant and equipment is carried out to increase the availability and reliability, so that it will continue to operate satisfactorily for the entire life-cycle of the equipment with required cost effectiveness. There are three main categories of maintenance strategies:

• Corrective or Breakdown Maintenance
• Preventive (Periodic or Fixed Time Based) Maintenance
• Condition Based Maintenance (CBM) or Proactive Maintenance

In CBM, Maintenance is carried out only when there is a need, as indicated by the measurement and analysis, using some of the several available condition monitoring techniques. These techniques  include use  of parameters  like  vibration  and  noise, temperature, lubricant condition, wear  debris  analysis,  corrosion,  pressure,  flow  and  other  performance  parameters.

This paper deals with condition monitoring techniques being used at CRM for different equipment and its benefits.
