Maintenance actions can be generally divided into three types: Corrective (Reactive) Maintenance, Preventive (Periodic) Maintenance and Condition Based Maintenance (Predictive). The corrective maintenance is performed upon failure to restore the system to a healthy condition, whereas the preventive is performed periodically to improve system performance. 

The Preventive maintenance program (PM) is the planned maintenance of asset designed to improve asset life and avoid unscheduled maintenance activity. Condition based maintenance attempts to evaluate the condition of an asset by performing continuous asset monitoring.  The most important reason to have a maintenance program with structural approach is to ensure that asset does not fail prematurely, that they keep producing or providing service as intended.  

The key of optimizing a facility’s maintenance program is to make the best choice for each asset as well as the facility as a whole.  

As part of NGGPD’s efforts to assure reliability of the existing equipment, a comprehensive Preventive Maintenance Optimization (PMO) review was conducted referencing to SABP-G-009. A total of (40) PM task lists were reviewed in terms of PM frequency, execution duration, and task-list quality.
