Preventive Maintenance Best Practices

The API Spec Q1 standard requires that organizations “maintain a documented procedure for the establishment of preventive maintenance for equipment used in product realization."  An effective PM program will reduce operating costs, improve product quality, and increase productivity for the company. Our goal is to minimize interruptions that  adversely impact productivity. With that in mind, we thought we would take this opportunity to discuss a number of best practices around the preventive maintenance process.
 
1. Preventive Maintenance factors:

Understand that preventive maintenance schedules are based on a variety of inputs, including:

• Usage history
  
• Risk analysis
  
• Manufacturer’s recommendations
• Industry recommended practices
• Regulatory requirements
• Internal experience
• Notable changes in system performance

2. Develop an actual plan

Most plans can be formed with a triggering mechanism. This means that certain events are slated to occur at a specific interval. The schedule may be developed with a condition-based or company-based protocol. The preventive maintenance schedule should always be assigned to a particular trigger.

3. Form the plan with savings in mind.
 
The plan should be developed with a specific set of savings objectives. Metrics like the maximum manufacturing time available for each machine may be used to create the schedule. There may be some downtime required where minimal lost production opportunity time may be factored into the planning process. There may even be a schedule developed around the concept affecting the quality of products manufactured.

4. Make the system available to others.
 
Once the framework has been constructed, the information should be created in some sort of a computerized maintenance system. The system will be formalized and assigned to key personnel responsible for monitoring the maintenance to be performed. The Accupoint system allows tasks to be automated and scheduled in a manner where work orders are generated on a timetable.

5. Set routine maintenance.
 
Once routine maintenance schedules are established for one system, move on to another critical system.  Again, set up maintenance schedules, documenting current conditions for future reference. An effective PM program can extend the asset life and ensures that it can be replaced as a scheduled event, rather than in an emergency situation.

6. Match the cost to the PM protocol developed.
 
It may be more cost-effective to perform a set of repairs simultaneously to a machine. It may also be much more cost-effective to take a reactive approach to maintenance. This approach may be better if this type of repair or maintenance duty doesn’t occur nearly as often.

In summary, a combination of inspections, repairs, and testing should be a part of any comprehensive preventive maintenance process. In addition,  any credible program should be long-term in nature.
