Reliability: Concepts and Trends

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.

Practical Maintenance Strategy Design For Capital Expansions

Same old story • • •

“This is my third plant expansion in 10 years. Next week we start with staged commissioning, but there is so much still to do.

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!”

by Owe Forsberg

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.

Does Your Company Need a Maintenance Culture Intervention?

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.
