NOTE: This post will be a little different from my normal posts. Instead of discussing a specific topic, I will be covering my journey in understanding Asset Management and some key takeaways from the journey. [Read more…]
Awareness of risk can lead to unforeseen risk behaviors based on knowledge that is sufficiently convincing to lead to false positives.

Roller bearing vibration measurement is one of the major condition monitoring tools in regular use. By measuring the velocity, acceleration and frequencies emitted from a rolling bearing it is possible to tell its condition and the likelihood of imminent failure. The technology is well established and well proven but requires a good understanding of equipment vibration characteristics before a user can draw good interpretations from the results.
Keywords: out of balance, vibration analysis, bearing life [Read more…]
Can you take into account reliability or durability functions in an FMEA? How can this be done? A reader asks this question, and it is discussed and answered in this FMEA Q and A article.
“A prudent question is one-half of wisdom.”

When your engineering project struggles, how do you respond? This video provides a sports analogy to the situation. Get back to the fundamentals – and Design of Experiments can be part of that process.

Often times organizations want to determine where they in their journey of asset management. This usually takes place in the form of benchmarking or assessing their asset management system against the standard. Before progressing any further, it is important to understand the difference between an assessment and an audit; [Read more…]
Probably one of the most recognized but least understood disruptive technologies for Risk Management in the 2020’s is Big Data. [Read more…]
Dust control concepts. Industrial dust is the result of material escaping from the confines of a process or a storage location. The size of the problem depends on the dust’s characteristics and the means of its distribution. The best policy to control dust is to not let it escape from where it ought to belong. There are simple techniques that can be used to manage dust and prevent it from becoming a major health and environmental problem once the mechanism of creation and distribution are under stood.

I have heard that “Reliability and Quality are kissing cousins” and also that “Reliability is Quality over time.” Neither of these definitions ring true to me. To be honest I’m a smidge offended because both of these terms diminish the value of the objective of reliability. I would state that reliability is “The design of a device or system so that it works as intended consistently over it’s defined use-life.” To me the key differentiator from my definition and the previous two descriptions of reliability is the word “design.”
In this article series, we covered several topics in the area of product development and project management. We will now begin to explore process improvement with the topic “Design for Lean”. While design for lean may be a subtopic within product development, it helps us understand operational risks, operational costs, enables operational planning and process improvement.
After years of consulting, what motivates us now? This video discusses those areas of interest for us. Constant learning and challenge keeps us going! [Read more…]
As we mentor RCM facilitators, we try to help them to develop strong techniques so that as they facilitate the RCM Blitz™ process they are able to work with any RCM team to develop a solid list of failure modes that are actually occurring to your equipment or are likely to occur at some time. One of the ways to become stronger at developing good failure modes is to be able to recognize a poorly written or bad failure mode. Below is a list of what we believe are common traps that result in the listing of poor failure modes. [Read more…]
The Global Forum on Maintenance and Asset Management (GFMAM) has worked with the major bodies (SMRP, PEMAC, IAM, etc.) to achieve a consensus on the major subjects within asset management.
These subjects are intended to describe the complete scope of topics within asset management. You can download the GFMAM guide for free here. It is important that anyone who wishes to understand asset management has an understanding of each of these topics, and hopefully some experience in each. [Read more…]
ISO 31000:2018 stresses the need for risk management to be integrated into operational functionality and decision making, but little has be written on how to actually achieve this. Scenario Analysis is not a modern technology but how you can provide operational management with risk based decision marking collateral. [Read more…]
Non-destructive testing of welds. Welding processes and methods can introduce contaminants and metallurgical defects into the weld. If a weld is required to withstand severe loading conditions and stresses it is critical to insure its quality meets minimum standards. Welds can be tested by destructive and non-destructive techniques. Most production is tested by use of non-destructive methods. The most common non-destructive tests to check welds are Visual Inspection, Liquid Penetrant, Magnetic Particle, Eddy Current, Ultrasonic, Acoustic Emission and Radiography. Keywords: NDT, quality control, non-conformance, verification, weld procedure. [Read more…]
