Another conspiracy theory debunked. Your business has various insurance coverages including business continuity. You pay quite a hefty premium for that coverage so you believe you are covered. But are you really?

When calculating the replacement asset value fo items brought overseas, factor the effect of the difference in exchange rate into the calculation.
[Read more…]Ahmed asks:
How can we calculate replacement asset value (RAV) of a plant? We have 100’s of equipment in our three plants and we cannot contact 100’s of Vendors to tell us today’s equipment value. We have only the Capitalization Cost or installed historic value of assets.
The oldest plant was installed 6 yrs back (Aug 2015) for a total plant or asset value in our accounting record of 10 MMPKR. When the plant was installed 1 USD = 100 PKR and now after 6 yrs the exchange rate is 1 USD = 172 PKR. We took the capitalization cost of 10 MMPKR and calculated replacement asset value at today’s worth as 10 * 172/100 MMPKR.
British engineer Robert Whitehead began his career producing textile weaving machinery in France. In 1856 he moved to the Adriatic coast to manufacture marine steam engines. He met Giovanni Luppis, an Austro-Hungarian navy officer, who had been developing a self-propelled coastal defense weapon that could be floated into an enemy fleet. Together, they failed to develop a practical weapon. Whitehead remained fixed on the idea of a submerged, self-propelled weapon. Working on his own for two years, Whitehead developed the modern torpedo. He sold his first units to the Austro-Hugarian Navy in 1867.

There is always a degree of uncertainty in selecting instrumentation for difficult or corrosive environments. Material selection for chemical compatibility involves a strained decision between cost and equipment reliability and longevity. The other major uncertainty is whether the instrument is appropriate for the application – will it repeatedly give truly representative readings all it’s operating life? This article presents a list of instrumentation successfully used in a range of difficult and chemically demanding environments.

Like Surfside, are you “inspecting to failure”?
In June 2021, we learned about the partial collapse of a condominium in Surfside Florida, with devastating results – only a few survivors, and many fatalities. The building had actually been inspected in 2018 by a qualified engineer, and parts of it were deemed to be “structurally unsound”. In plain English, that means the building’s structure was no longer in good condition and possibly dangerous. It was unsafe to use. The report was submitted to a local authority who raised no red flags, and the building owners chose to do nothing about it. Roughly 3 years later – disaster. It’s a sad example of “inspecting to failure”.

Competency is defined as the capability to apply or use the set of related knowledge, skills, and abilities required to successfully perform a task or work safely and consistently to a required standard. Simply stated, Competency is a critical skill set needed to do a job successfully. On the other hand, Certifications are designated credentials earned by an individual or organization to verify their legitimacy and competence to perform a job or produce something in a stated environment.

Reactive Maintenance can be costly and frustrating. Avoid chronic breakdowns by moving towards Proactive Maintenance. In this video I share how Reliability Centered Maintenance (RCM) can help you move from Reactive Maintenance to Proactive Maintenance.
[Read more…]If you believe that reliable operations will result if you just follow your maintenance program, then you might also believe a few falsehoods about reliability and maintenance. First is the falsehood that maintenance is all you need to achieve reliability. Maintenance is about sustaining the asset’s operating conditions, not just fixing it when it breaks. Indeed, you do need to follow your maintenance program but it is not all there is to do, and it had better be the right program.

A presentation by Mike Sondalini at the Shutdowns and Turnarounds 2011 Conference.
The presentation covers:
A well-designed maintenance program should eliminate the need to do condition assessments. These assessments are a form of condition monitoring, so why not include them in your proactive maintenance (PM) program? They are carried out to determine the current condition of an asset, determine if any remedial work is required, make an estimate of how long it will last, and forecast timing for eventually replacing the asset. In civil structures like buildings and bridges, these assessments are often called, “inspections”. When timed regularly they are no different from a condition monitoring task in any PM (proactive maintenance) program. Yet, they will be managed differently. Why that is so, doesn’t really matter, but arguably it just adds another program that must be managed in parallel with your maintenance program.

Step Two: Be Honest With Yourself
Self-accountability is meaningless without honesty. It can be difficult to be honest with yourself, because then you’re pulling away all the excuses and rationalization that stand between you and what you want, but it’s the only way forward.

Companies are constantly looking for ways to identify and implement cost-saving measures. Computerized maintenance management software is used to record, manage, and communicate day-to-day operations in your maintenance department. It’s possible to use CMMS to save money in a number of ways. The following are areas in which large cost savings can result through the implementation of equipment maintenance software

The Plant and Equipment Wellness Way lets organizations make their operating assets world class reliable so they can enjoy operational excellence success. A Plant Wellness Way EAM System- of-Reliability puts the reliability processes, skills, paradigm, and culture into companies that creates world class reliability and operational excellence.
[Read more…]Do you have a reliability department, a maintenance department, or a repair department?
Do you avoid failures? Do you avoid or mitigate their consequences?
Or do you wait for things to go wrong, then fix them?
Repairs are all about fixing what has broken. When something breaks you lose whatever functionality it had. It more than likely broke when you were using it too. So you also lost the benefit of that functionality – often production or service delivery capability. The costs include repair, whatever secondary physical damage occurred, the loss of revenues and profits, plus safety and environmental consequences that arise. When something breaks its “useful life” is reduced – deterioration was allowed to accelerate, so even once repaired, the asset has lost some future useful life. The fix for that longer-term deterioration impact is a capital replacement – earlier than need be. If the breakdown was really bad, then it might be much sooner.
