Preventive maintenance

Where equipment is maintained before break down occurs. This type of maintenance has many different variations and is subject of various researches to determine best and most efficient way to maintain equipment. Recent studies have shown that Preventive maintenance is effective in preventing age related failures of the equipment. For random failure patterns which amount to 80% of the failure patterns, condition monitoring proves to be effective.

Preventive maintenance is maintenance performed in an attempt to avoid failures, unnecessary production loss and HSE violation. As equipment cannot be maintained at all times, some way is needed to decide when it is proper to perform maintenance. Normally, this is done by deciding some inspection/maintenance intervals, and sticking to this interval more or less affected by what you find during these activities. The result of this is that most of the maintenance performed is unnecessary it even adds substantial wear to the equipment. Also, you have no guarantee that the equipment will continue to work even if you are maintaining it according to the maintenance plan.

Corrective maintenance

Where equipment is maintained after break down. This maintenance is often most expensive because worn equipment can damage other parts and cause multiple damage.

Corrective maintenance is probably the most commonly used approach, but it is easy to see its limitations. When equipment fails, it often leads to downtime in production. In most cases this is costly business. Also, if the equipment needs to be replaced, the cost of replacing it alone can be substantial. It is also important to consider health, safety and environment (HSE) issues related to malfunctioning equipment.

Corrective maintenance can be defined as the maintenance which is required when an item has failed or worn out, to bring it back to working order. Corrective maintenance is carried out on all items where the consequences of failure or wearing out are not significant and the cost of this maintenance is not greater than preventive maintenance.

Reliability maintenance

Reliability maintenance is a process to ensure that assets continue to do what their users require in their present operating context

It is generally used to achieve improvements in fields such as the establishment of safe minimum levels of maintenance, changes to operating procedures and strategies and the establishment of capital maintenance regimes and plans. Successful implementation of Reliability maintenance will lead to increase in cost effectiveness, machine uptime, and a greater understanding of the level of risk that the organization is presently managing.

Reliability Maintenance can be used to create a cost-effective maintenance strategy to address dominant causes of equipment failure. It is a systematic approach to defining aroutine maintenance program composed of cost-effective tasks that preserve important functions.

The result is a maintenance program that focuses scarce economic resources on those items that would cause the most disruption if they were to fail.

Reliability maintenance emphasizes the use of Predictive maintenance (PdM) techniques in addition to traditional preventive measures.

Predictive maintenance

Predictive maintenance is evaluate the condition of equipment by performing periodic or continuous (online) equipment condition monitoring. The ultimate goal of Predictive maintenance is to perform maintenance at a scheduled point in time when the maintenance activity is most cost-effective and before the equipment loses performance within a threshold. This is in contrast to time- and/or operation count-based maintenance, where a piece of equipment gets maintained whether it needs it or not. Time-based maintenance is labor intensive, ineffective in identifying problems that develop between scheduled inspections, and is not cost-effective.

The “predictive” component of predictive maintenance stems from the goal of predicting the future trend of the equipment’s condition. This approach uses principles of statistical process control to determine at what point in the future maintenance activities will be appropriate.

Most Predictive maintenance inspections are performed while equipment is in service, thereby minimizing disruption of normal system operations. Adoption of Predictive maintenance can result in substantial cost savings and higher system reliability.

Planned maintenance

Planned Preventative Maintenance (‘PPM’) or more usual just simple Planned Maintenance (PM) or Scheduled Maintenance is any variety of scheduled maintenance to an object or item of equipment. Specifically, Planned Maintenance is a scheduled service visit carried out by a competent and suitable agent, to ensure that an item of equipment is operating correctly and to therefore avoid any unscheduled breakdown and downtime.

Together with Condition Based Maintenance, Planned maintenance comprises preventive maintenance, in which the maintenance event is preplanned, and all future maintenance is preprogrammed. Planned maintenance is created for every item separately according manufacturers recommendation or legislation. Plan can be based on equipment running hours, date based, Planned maintenance has some advantages over Condition Based

Maintenance such as:

  • easier planning of maintenance and ordering spares,
  • costs are distributed more evenly,
  • no initial costs for instruments for supervision of equipment.
  • Disadvantages are:
  • less reliable than equipment with CBM
  • more expensive due to more frequent parts change.
