The binomial distribution is a discrete distribution useful for estimating the probability of success or failure when these are the only two possible outcomes. Thus, the prefix, “Bi”. Understanding the binomial distribution — how it’s used and under what conditions – is therefore a valuable analytical tool for reliability engineers.

Reactivity hazards involve conversion of stored chemical energy of the components into mechanical or heat energy, andit is the uncontrolled release of this stored energy that causes the damage in a reactive chemical incident. The reactivity of a substance is normally assessed by performing calorimetric measurements.

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.

Your team knows what Operation Within Specification (OWS) is for its product. This is the set of performance limits confirmed in the laboratory using API product standards. These limits help establish the ratings for parameters such as pressure, mechanical load, operating temperature, and other parameters found in operating manuals.

In my travels over the past 35+ years talking to RCA analysts around the world, as well as those outsiders who look into our ‘RCA’ bubble, I find many misconceptions about RCA. This happens in every space, just think about RCM, RBM, APM, CBM and the like; everyone experiences how other people view their craft.

In a recent article, I shared that every written or verbal communication needs a structure. Aristotle believed that every poem or theatrical performance should follow a three-act structure. The three-act structure stands the test of time in all forms of writing and performing arts. It is also a straightforward and extremely efficient structure. More importantly, it works subtly but effectively with our human thinking processes.
The three-act structure is alive and well in the series “Communicating with FINESSE” on Accendo Reliability. Act One – the Opening – frames what is to come in Act II and lays the foundation of Systems Thinking needed for effective communications. Check out the building story of Act One in these articles: The One Thing Your Approach to Communication & Facilitation is Missing, Effective Communication Is The #1 Thing That Changes Your Life, and Do You Know These Dirty Secrets of Effective Communication?

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”.

I was once taught that good project management and mitigating the risk of failure was a combination of Fayol’s three pillars of planning, organising and controlling glued together by effective communication and enclosed in a bubble of morale. I was later to learn that that if one overindulges or ignores any one pillar, or fails to communicate effectively rather than just efficiently, the oftentimes thin bubble of morale may rupture. The unfortunate result is the loss of management coherence and the real possibility of project 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.

Chemical industry has evolved dramatically since the first sulfuric acid manufacturing plant was established in the 18thcentury. Modern day chemical plant is an engineering marvel producing valuable chemicals necessary for the societal progress. Although safe for the most part, chemical industries have witnessed a few significant accidents in the last two decades. The Bhopal disaster marked the turning point in the history of chemical plant’s process safety. The Bhopal disaster resulted in an increased concern and anxiety among everyone safe operation of a plant. There are several landmark events that followed the 1984 Bhopal disaster:

The following article was published in Plant Services earlier this year with the title, “Don’t get stuck in reactive mode – The world of fantasy maintenance is calling you”. The alias of the author is Captain Unreliability, so all credit should go to the Captain:-).
To the veterans in the field, you will connect with this article in a heartbeat. You will be laughing all along the way. In the end, I will add a commentary about while this may appear comical, it sadly is reality in many places that we all work (or have worked). But I’ll leave that up to you, to be the judge. In the end, please relate your own experiences and let me know if this is B.S. in your world or not!
We had met at the same place, at the same time, and in the same format every month for the past six months. The team still had eight months to go to complete the master plan. For the past three months, half of the sessions included breakout groups where participants worked together to develop key aspects of the final document. Everything was being performed just like everyone had agreed in the project charter. However, the burnout could be seen in their eyes and heard in their voices…
A seasoned team had designed a week to do Failure Modes and Effects Analysis (FMEA). We would spend a slow-paced Monday afternoon working through the plant overview and a low-intensity Friday morning reviewing what we had done over the week. Everyone was committed to an intense, action-packed middle three days where we would get most of the heavy lifting done. However, by mid-morning Thursday, it was apparent that interest was fading fast…
“Honest disagreement is often a good sign of progress” – Gandhi
The Oxford English Dictionary defines “conflict” as, “an incompatibility between two or more opinions, principles, or interests.”
Conflicts are bound to arise from time to time. They can be positive and beneficial. An absence of any expressions of disagreement or conflict may indicate a problem in adequacy or quality of facilitation. Facilitators should not be afraid of conflict, but should learn the value of disagreements and how to manage them. Understanding the difference between healthy debates and dysfunctional arguments is critical to good facilitation. [Read more…]
