That Won’t Work Here! How to Overcome the Top 5 Excuses
One of the most challenging aspects of being a consultant is addressing the musings of those who have accepted defeat.
With a smile of course; and friendly reassurance that you have in fact worked with companies who were worse off and with some training, confidence and a sound business plan they were able to turn things around to a point where people actually enjoyed coming to work. [Read more…]
See How Easily You Can Plan a Successful Shutdown
Using the Critical Path to Guarantee a Successful Shutdown
Shutdown, Turnaround, Outage are all the same thing. An extended planned downtime event, in which a tremendous amount of resources are utilized to ensure the site will be able to achieve its business goals. Whether the shutdown involves overhauls, CAPEX or a combination, the successful completion of the shutdown depends heavily on the planning and execution of it.
Shutdowns are resource intensive and often under compressed timelines. This unique situation requires a different approach to planning, scheduling and executing work, than the typically Maintenance Planning & Scheduling process. [Read more…]
Separation and Segregation of Dangerous Goods
Many of the chemicals we deal with each day are dangerous and need to be handled correctly and safely. Safe use of dangerous goods includes recognising when situations can arise where the consequence of a failure or error will result in danger to life, property or the environment. One of the methods used to minimise risk when dealing with dangerous goods is by separation and segregation.
Keywords: Hazard, storage facility, control, emergency plan, MSDS, material safety data [Read more…]
Things I Learned by 50!
It’s Friday so I thought I would go back in the archives and find something light and meaningful. Enjoy 🙂
Old is relative.
I can remember thinking my dad was old when he turned 50. While I might look old to my kids I don’t feel old. When I look in the mirror each morning I still see the person I saw yesterday and he doesn’t look any older than he did the day before. [Read more…]
What Everybody Ought to Know About Work Order Closeout
How Capturing the Right Information Will Improve Your Job Plans, Increase Reliability and Improve Your Profitability
One of the most important, but often the least effective parts of the Maintenance Planning & Scheduling process, is the work order close out step. Here critical data is supposed to be captured and used to improve the job plan, identify future work and improve reliability. All of these add up to improve the profitability of the organization.

Increase Productivity and Competitiveness with MRO Technology – Part 2
Excluding primary practices that still prevail in most industrial companies, the evolution of MRO Materials Management Technology can be summarized in three technological waves, as shown below.
First Wave: Conventional Technology
There are many grave technological limitations. However, in view of room limitation, I will mention just two of the most relevant and easy to understand limitations. [Read more…]
Heating Liquids by Steam Sparging
Steam is often used for heating liquids. Heat is provided to a liquid either through a heat exchanger or by direct injection of raw steam. The injection of steam directly into the process is known as steam sparging. The sparge design and location affect the efficiency of the process.
Keywords: boiling, heating water, temperature increase, injector, lance, boiler pressure, properties of steam. [Read more…]
4 Differences Between Leaders & Managers
While working in the field of Asset Management formerly known as Maintenance and Reliability for over 30 years I have worked with my share of Managers and Leaders. Those who have known me for years know that I started in the field as a Pipefitter Apprentice, worked as a Journeyman and Team Leader for a number of years, did a stint as a Maintenance Supervisor, went to night school to become a Reliability Engineer and then as a business owner working with customers around the world.

Increase Productivity and Competitiveness with MRO Technology – Part 1
In search of excellence in MRO Materials Management (indirect materials / spare parts), I have noticed two curious facts.
First, even in developed countries, industrial companies and providers of ERPs (enterprise management systems) are technologically very backward in this specialty.
Second, those very little companies or experts who developed differentiated technology keep it safe guarded as a trade secret.
This exposure results in considerable accumulation of knowledge and expertise, and a unique set of observations and conclusions which certainly could not fail to be shared with the concerned community. [Read more…]
The 5 Levels of Maintenance Scheduling
Making Maintenance Scheduling Simple
Coordinating all of the maintenance activities within a site can be overwhelming. A schedule is supposed to help reduce the sense of being overwhelmed. But why is it that when trying to pull together a schedule for the next shift, day or week, it always seems to be a mad dash?
Often times the maintenance scheduling process is not well defined or thought out, and this leads to being overwhelmed. It also projects an image to our operational partners that we do not have our house in order. This image may or may not play a role in having our Maintenance windows moved or cancelled, further our scheduling issues. [Read more…]
Differential Pressure Transmitters
The differential pressure transmitter (PT) is used to detect a head of pressure.
The sensing element is connected to the process by pipework and flexes in proportion to the pressure. The resulting distortion produces an electric signal that is amplified and converted to a value on a read-out.
Keywords: pressure sensor, strain gauge, tank level, process pressure, pressure difference. [Read more…]
Safety Is a Lifestyle
Something to think about in a day and age when most companies post their mission, vision, and goals on the company web page.
Do we really stand behind these statements and demonstrate the behaviors that clearly show we are willing to do what it takes to create a safe workplace?
If you have ever questioned this, consider two questions I ask RCM Teams as we analyze failure modes that impact health, safety, and environment: [Read more…]
Linking RCM Facilitation with Effective Maintenance Program Implementation
Most of us would agree that there is a new global economy being forged right now in the manufacturing sector.
Inevitably, this translates to a renewed focus on transferring more business value to the customer. Central to this will be linking RCM (Reliability Centered Maintenance) facilitation with effective maintenance program implementations.
In short, the difference between what we, as RCM Facilitators, have been doing in the past and what we will be doing from now on is: a strong emphasis on what tactics are required in order to achieve the failure management strategies an RCM Team defines.
That is, we will conduct the decisions phase of the analysis somewhat differently. (i.e. The 3rd pass through when walking-the-dog in an RCM analysis) [Read more…]
The Black Hole of Maintenance
Where Maintenance Requests Go But Never Appear to Escape From- the Backlog.
This is exactly what some operations staff think of when we tell them to submit a work request.
It means that they do not think that the work will be completed, or it will after it no longer matters to them.
What if you called the cable company and reported an issue? You would expect prompt service, and would expect that you would not have to chase them down to do the work correct? Maintenance is a service organization that enables the successful operation of the business.
The business shouldn’t have to chase us down or wonder if we will repair the equipment. [Read more…]
