Definition - What does Preventive Maintenance mean?
Preventive Maintenance is a timely maintenance of the oil and gas equipment that is regularly performed as per the prescribed maintenance schedule of the equipment supplier or as per the oil and gas organization which is using the equipment. It is carried out so as to reduce the likelihood of machinery failure. Preventive Maintenance is also performed on oil and gas wells if they are not functioning effectively and when some deformations start taking place.
Petropedia explains Preventive Maintenance
Preventive Maintenance should not be treated same as breakdown maintenance as preventive maintenance is performed when the equipment is still in good working condition so that it does not break down unexpectedly. Thus, preventive maintenance is a planned maintenance as per the schedule prescribed by the vendor who supplied the equipment or as per the scheduled designed by the user of the equipment.
Generally the assets that undergo preventive maintenance include those which have:
- To operate in critical conditions
- More failure chances due to harsh operating conditions
- Equipment that has been aged and needs more cautious observations.
Advantages of preventive maintenance include:
- Planned maintenance schedule, therefore, the manpower is ready for the maintenance process.
- Maintenance can be performed without disfunctioning of plant.
- Long life of machines.
- Efficient operations.
Disadvantages of preventive maintenance include:
- Investment in time and resources.
- Can occur too often whenever a small problem is seen, i.e., frequency of preventive maintenance is high.
