How to use Condition Based Maintenance Strategy for Equipment Failure Prevention

Most equipment failures have no relationship to length of time in-service. Most failures are unpredictable. But if you detect a future failure early, you can plan and do the repair cost effectively before it becomes a breakdown.

With only about 15% to 20% of your equipment failures being age related, and the other 80% to 85% being totally time-random events, how can you improve the uptime of your plant and facility? This article explains how to detect the random failures that make-up the vast majority of maintenance expense and production downtime by using simple, low cost condition monitoring methods.Keywords: equipment condition monitoring, random equipment failure, equipment failure patterns

Maintenance Strategy 202: Develop your equipment maintenance strategy, then develop your equipment maintenance programs

First develop maintenance strategy—what you want to achieve with your equipment maintenance, why it is necessary, and how to do it.

Then turn strategy into the plans to maintain production asset reliability with the equipment maintenance program.

Often maintenance managers and maintenance engineers are asked to develop a maintenance strategy for their plant and equipment. They need to develop a document. In it you explain how you are going to use the least plant and equipment maintenance expenditure and efforts to ensure the necessary production performance from your production plant and equipment.

There is a direct connection between the microstructure health of your equipment parts and your operational and business success

There are key concepts and practices that an organization needs to use if they want optimal asset health from their plant and equipment. The greatest successes come when operating and safety risks are eliminated at their root causes. The Plant Wellness Way EAM methodology focuses on getting lasting asset health so world class operating performance is normal in your company day-after-day. Its processes and analysis tools create a system-of-reliability that gets exceptional asset health and delivers the greatest ROI from each operating asset throughout its service life.

Risk is the total losses suffered when any asset’s components may fail. The causes of failure are the environmental and operating stresses that affect a component’s microstructure. This means that world class reliability is the effective, complete remove of the causes of failure, also known as risks, from your operations. [Read more…]

 How do you work-out the right life-cycle maintenance strategies? Does one strategy apply throughout an asset’s life? What influences the choices and decisions as to what maintenance to do and when it should be done? How much money and resources do you expend in the maintenance of an asset? To keep the concepts behind these important questions on maintenance strategy selection simple they are applied to a sheet of paper.

If you want to drastically reduce maintenance costs, stop lost production, eradicate unplanned outages and equipment breakdowns, you need to stop the continual introduction of defects and errors into your operation.

You do that by using quality management practices to drive continuous improvement of your management systems and so continuously improve the business processes, and your peoples’ knowledge.

Abstract:

To reduce maintenance costs and production downtime it is necessary to reduce the causes of the maintenance and downtime.  Both maintenance and downtime are an effect and not a cause.  The causes can be traced back to defects and errors from a variety of sources.  Knowing that defects eventually lead to future equipment failures, production downtime and lost profits, it is necessary put strategies into place to purposely prevent them occurring in the first place and to eliminate them if they are present.

 High equipment reliability is a choice and not an accident of fortune. To a great extent you can choose how long you want between equipment failures. You can deliver high equipment reliability by ensuring the chance of incidents that cause failures of equipment parts are low. The secret to remarkably long and trouble-free equipment lives is to keep parts and components at low stress, within good local environmental conditions, so there is little risk they are unable to handle their design duty. If there is nothing to cause a failure, the failure will not happen and your equipment continues in service at full capacity and full availability. 

For maintenance practitioners, it is the use of precision maintenance backed-up with condition monitoring applied as a tool to prove maintenance work is done precisely, that provides the foundation for exceptional equipment reliability.

Find the fortune maintenance can make for your business. Unfortunately, maintenance people get praise when they repair breakdowns. This embeds and promotes a culture of equipment failure acceptance in a business. Maintenance must be used to prevent equipment failures, not fix them. If you want to start a culture of failure elimination in your business you have to start putting a money value on the breakdowns prevented by Maintenance. You have to start praising and recognising them for the breakdowns they didn’t let happen. Maintenance needs to be praised and glorified for the money it makes a company, not singled out for the money it spends.

Many companies adopt root cause failure analysis (RCFA) and then drop it. They use it for while and get no benefit. RCFA is often ineffective when used to solve individual problems. But when used to find systematic causes of problems and improve business systems, it provides grand payback for the effort.

Much of what we do in engineering and maintenance we accept without question. People say, ―It‘s been done that way for decades,‖ implying that it must be correct. But for equally as many decades have come stories of failed and broken machinery, plant and businesses. On one hand we continue to unquestioningly do what has been done for generations, yet on the other hand we cannot stop equipment failing. There is a subtle connection between the two of which we are only just becoming aware. The connection is obvious when you realise that we have been running our businesses by risk and luck, and not on facts and understanding.

When you do a Root Cause Failure Analysis or a 5- Why there are no promises that you will actually find the true root cause and fix your problem. Investigating the cause of a failure is fraught with traps, such as making wrong assumptions, insufficient evidence, misinterpreting the evidence, misunderstanding, personal bias and second-guessing. There are necessary issues you need to be aware of that affect the RCA and 5-Why methods, and there are some good practices that you can adopt to improve your chance of doing a successful analysis when applied to equipment failures.
