Welcome to part eight of my 10-part series of blogs called “Uptime Insights”, where we explore a journey of excellence in maintenance. To stay on top, managers must implement strategies that keep operations performing at high levels. In these articles I will show you how to achieve excellence in maintenance – a critical business process in any capital intensive industry. [Read more…]
Pressure vessels must be regularly inspected and be maintained in a safe operating condition.
New Australian laws stipulate that all pressure vessels must have a Hazard Level rating (‘A’ highest to ‘E’ lowest) which reflects the vessel’s safety risk (see AS3920.1).
The higher the risk the more stringent the requirements for operating and inspecting the vessel.
Keywords: receiver, non-destructive testing, internal inspection. [Read more…]
We hear a lot about things that are being called “Black Swans” today thanks to Nassim Taleb and his extremely successful book, “The Black Swan: The Impact of the Highly Improbable,” now in its second edition. I have written several articles centering on the “Black Swan” phenomenon; defending, clarifying and analyzing the nature of “Black Swan” events. And, I am finding that wildly improbable events are becoming perfectly routine events. [Read more…]
One of the simplest ways to learn design of experiments, DOE, is to just give it a try.
The Taguchi DOE approach uses orthogonal arrays. This subset of the possible approaches to DOE simplifies the process to create and analyze experiments.
Let’s plan a simple experiment using the Taguchi DOE approach. [Read more…]

Get mechanical seals working properly.
Mechanical seals are used to keep the bulk contents of rotating equipment such as pumps and compressors from escaping. They do this by sealing the shaft that protrudes from the casing.
They require quality installation and operating conditions for a long life. [Read more…]

In order to improve business performance, manufacturing companies need to reduce the levels of non-conformance and attendant failure costs stemming from poor product design and development. Failure costs generally make up the largest cost category in a manufacturing business and include those attributable to rework, scrap, warranty claims, product recall and product liability claims. This represents lost profit to a business and as a result, it is the area in which the greatest improvement in competitiveness can be made. [Read more…]

More ISO management systems are incorporating RBT and risk, so the standard is becoming a ‘must know’ standard. ISO 31000 risk management principles, risk management framework, and risk management process are the preferred tools to use with ISO management systems because ISO 31000: [Read more…]
Vibration from out-of -balance rotating equipment can be frightening.
The ground shakes, machines jump about, hold down bolts come loose and parts break.
An unbalanced rotating body will produce forces on its bearings and transmit them throughout its structure and into the foundations.
Keywords: rotor, centrifugal forces, balance quality. [Read more…]

Every day we are exposed to all types of hazards, but what really makes these hazards become risks.
For the past 30 years, I’ve been involved in one way or another, investigating the root causes of failure modes be it a system, process, person, plant or product. During this time I’ve applied different problem-solving tools like “FMEA, 8D, 5Whys, FEA’s, DMAIC etc” in order to find the true root cause of this failure mode. Only to get frustrated, thinking I had found the root cause, only 3 months later a new failure mode would come to the surface. [Read more…]
Don’t run centrifugal pumps on the end of the curve. Pumps are designed and selected to operate near their highest efficiency point.
If they operate at the right-hand end of the pump curve the likelihood of cavitation increases.
Keywords: suction pressure, flow velocity, vapor pressure, duty point. [Read more…]
I’ve been managing supplier relationships for almost my entire career, including hardware component suppliers, contract manufacturers, technology alliance partners, and engineering service providers.
Over that time I’ve worked with a number of people at all levels who seem to believe that their one-up position as the customer entitles them to demand more from suppliers while paying less.
The attitude seems to be: “Do as I say or we’ll take our business elsewhere.” [Read more…]
