Welcome to Part 4 of our Reliability Centered Maintenance (RCM) Case Study, where we take a deep dive into Condition Based Maintenance (CBM). CBM, also known as On-Condition Maintenance, is a proactive approach that allows us to detect Potential Failure Conditions and take corrective action before failure occurs. In this video, I explain:

What Condition Based Maintenance is and how it works
The role of the P-F curve in determining CBM task intervals
A Real-life example of a CBM task
Why the P-F interval is used to set CBM task intervals
How CBM differs from Preventive Maintenance and other strategies

Reliability Engineering – Science of Pessimists?

Introduction

This is a rather depressing title for an article specifically on the topic of Reliability. After all, Reliability relates to the Probability of Success hence the contradiction.

However, the contradiction is not so much one as Reliability Analysis depends on having access to failure data. In other words, if the equipment does not fail, it might be difficult or even impossible to perform an analysis. Of course, we can source other types of data that are not failure records, but this is not the common approach.

Measuring Replacement Asset Value (RAV)

I read your article that compares maintenance costs to RAV and am inquiring to see what is your definition of ‘maintenance cost’ when measuring replacement asset value? Are you strictly referring to labor costs, or is this the cost of labor, services and capital equipment purchases to repair, replace or upgrade an existing machine?

Dear Tom,

In the example, ‘maintenance costs’ meant the direct and overhead maintenance costs – labor, parts, subcontract services and allocated overheads (i.e. supervision, management, associated infrastructure, etc. proportioned to direct labor hours) – incurred during the ‘normal’ operation of the car (i.e. the car is driven by a well-trained, responsible driver at the wheel). If you have a store/warehouse for maintenance parts then you add the proportionate cost of keeping and running the store to support the maintenance effort as part of the total cost of maintenance.

RCM Lesson from the Ancient Mayans

Discover the Secret to Reliability

Hi everyone! I’m Nancy Regan, and today I’m coming to you from the iconic pyramid of Chichen Itza in the Yucatan Peninsula, Mexico. The ancient Mayans believed that their pyramid connected them to both the underworld and the sky—a symbol of balance and connection. This powerful idea got me thinking about Reliability Centered Maintenance (RCM) and the importance of leveraging our most valuable resource: equipment experts.

In this video, I’ll explain why equipment experts are crucial to the RCM process. They bring insights that historical data alone can’t provide, understanding how things fail, what causes them to fail, and how each failure matters —what we call consequences in RCM. Documenting their knowledge through RCM not only improves reliability but also preserves their invaluable expertise for the future.

Today’s Gremlin – I’ve got this!

Today’s Gremlin – “I’ve got this”, doesn’t cause trouble. In fact, he’s very motivated to keep things running smoothly. He’s good at what he does and he does keep things running. But, he’s a gremlin because he doesn’t know what he doesn’t know. Sometimes, he is closed to new ideas, thinking he has been there, done that and seen it all, but doesn’t realize that he really hasn’t. What he knows, he puts to good use. What he doesn’t know is where the limitation arises.

Ageless Maintenance and Reliability Success Secrets 5

Maintenance and reliability problems are not new. Our forefathers and ancestors understood the value of smart maintenance and high reliability. They learnt from experience and passed their knowledge down to us through parables, stories, and sayings. The timeless advice of our forbearers on successful maintenance and reliability is as applicable to us now as it has been to every generation since the dawn of civilisation.

RCM’s Hidden Power EXPOSED in Step 7

Hi everyone! In this video we use Reliability Centered Maintenance (RCM) principles. Yesterday, we poured the concrete floor for our metal building, and I learned that newly poured concrete faces a unique Failure Mode: Water evaporates too quickly during drying due to normal environmental conditions. This can lead to excessive cracks that compromise the strength of the structure.

In Reliability-Centered Maintenance (RCM), Step 7—Default Strategies—helps us determine how to manage specific Failure Modes that require unique actions. In this case, the solution is to keep the concrete wet for at least three days, and luckily, Mother Nature is giving us a hand this weekend!

Remember, RCM isn’t just about routine Proactive Maintenance. Sometimes, your equipment may need special, one-time actions or other Default Strategies to manage particular Failure Modes.

Component Lifetime Health Strategy Based on Physics-of-Failure Science

Plant and Equipment Wellness (PEW) is a Physics of Failure based methodology for equipment failure prevention and defect elimination that results in the fewest activities, least resources and lowest expenditure to produce outstanding operational equipment reliability. PEW identifies the necessary business-wide processes and departmental actions an organisation needs to apply to get high plant and equipment availability. With high uptime comes more productivity, higher operating profits, and less capital expenditure.

As much as possible PEW uses simple techniques that can be done by shopfloor people. Most companies do not have large staffs of university trained maintenance and reliability professionals. They have knowledgeable and experienced maintenance practitioners that know their plant and equipment. PEW does not require specialist RAMS software that none but mathematicians can understand, that very few companies can afford to buy or contract, and requires assumptions about the future that are hopeful at best.

Reliability Centered Maintenance Explained

Hi everyone! Today, we’re pouring the concrete floor for our metal building, and it’s a perfect analogy for Reliability Centered Maintenance (RCM). Just like this concrete forms a solid foundation that will support our structure for decades, RCM isn’t a quick fix or the program of the week. It’s about building a lasting foundation for your reliability efforts.

RCM takes time, the right people, and a commitment to the process to develop proactive maintenance tasks that truly make a difference. Build for the long term—invest in RCM and lay the groundwork for future reliability!

Outstanding Maintenance and Reliability for Everyone

Maintenance And Reliability Like They Should Be Done!

What can a 25-year veteran of condition monitoring tell you about how to do better maintenance and get
better reliability?

First a little background. Max started his vibration analysis monitoring company back in the late 1970’s. He and his company developed expertise and technologies in condition monitoring over many years. They monitored and reported on a large range and number of machines, and worked for numerous companies. He and his people were the recognised experts in vibration monitoring and control.

Today’s Gremlin – Sweat the Asset

Today’s Gremlin – “sweat the asset”, truly believes that running the plant and equipment as hard as possible is good for business. He couldn’t be more wrong!

This gremlin wants to produce more in a short time and runs the equipment at or even over its design capacity. In one plant in a big mine I met one of these – a production superintendent who believed he was doing his best when he ran the plant hard and just avoided tripping breakers! Running that hard increases stress on the equipment, often ends up in overloading it, and causes it to fail prematurely.

Reliability Software – Avoiding White Elephants

Introduction

Software packages and algorithms help speed up calculations in Reliability Engineering Analysis. And obviously in other specialties. They are known as Commercial Off-The-Shelf (COTS) Software. Preprogrammed formulas can be readily applied by the analyst to provide modeling results. Additionally, graphics and other informative visual representations can be obtained at a mouse click. This helps showcase issues in an operating environment. And lead to relevant action to address those issues. Our human brain has cognitive limitations when analyzing highly complex systems such as Reliability, Availability and Maintainability (RAM) Models. Software helps to overcome those limitations.
