The most known concept to define reliability is: “Probability that an asset or system operates without failing during a given period of time under some operation conditions previously established.”
Sometimes, this concept is wrongly used due to the particular use given to the word failure. For many, failure only means shutdowns, so they construct complex mathematical formulas to calculate shutdown probability without taking into account that a failure also occurs when being inefficient, insecure and costly, having a high rejection level, or contributing to a bad image.

Research into bearing failures1 shows that just over half of them are a result of contamination of the bearing oil (Figure 1). Clearly, it is essential to ensure that this is minimized and, if possible, eliminated to achieve the optimum bearing life necessary to improve equipment reliability. Continue reading

Asbestos Risk in Manufacturing Plants
Asbestos use inside manufacturing plants was common practice in the United States throughout most of the 20th century. It was incorporated into thousands of products and a lot of industrial machinery was made with asbestos-containing parts. Continue reading
Maintenance personnel go to work and do their jobs taking measurements and writing reports, often with great care and skill. Their reports and recommendations then travel into a deep abyss from which they never return. Sound familiar? This situation is all too common in the condition monitoring (CM) world.

“This is my third plant expansion in 10 years. Next week we start with staged commissioning, but there is so much still to do. My Maintenance Planner and Team Leaders are breaking down my door, asking for resources to develop their maintenance strategies and populating our CMMS. We have not even yet finished the previous expansions’ plans! The design company is demobilizing, and the engineers will be occupied for months with process optimisation. And I don’t have approval for my Reliability team yet! It will take years to get the strategies done now that we’ve reached the end of our capital resources!”

In best practices, a closeout review or critique meeting gathers all the information from the last event and uses it to prepare for the next event. It is the ammunition your organization can use to either support the current Shutdown/Turnaround/Outage process as cost and safety effective or to challenge how the process is currently performed.
Unfortunately, many organizations either don’t do the review or have the meeting and do not use the information to impact the next shutdown cycle.
Spindles are one of the most expensive and sophisticated rotating components on the planet. They rotate at super high speeds with fits and tolerances 10 to 20 times what is required on other rotating devices, such as pumps or motors. If there ever were machines that needed to communicate their health and activity it would be spindles.
Let’s face it, most companies need a culture intervention – something like a 12-step program. This article will explore behavioral issues that are often at the core of a culture of neglect and mediocracy. It borrows much from management science, leadership principles and conversations with individuals working in the field of maintenance reliability.
Traits of a Bad Maintenance Culture
It doesn’t take long to recognize the signs of a bad maintenance culture, although the profile of this culture can vary considerably. The culture profile might be characterized by indifference, blame, tension between operations and maintenance, frustration or anger, distrust, pessimism, high staff turnover, waste of time and resources, excessive human errors, an aging work order backlog, frequent unscheduled maintenance events, crisis and unprofitability.

At times, this debate has been contentious, pitting one department or function against another, with the winner being, in many cases, who can yell the loudest or who has the most sway with top executives. The key participants in the ERP vs. EAM debate are most often finance, IT and operations.
