Tony Sofronas, D. Eng, was the worldwide lead mechanical engineer for ExxonMobil Chemicals before retiring. He now owns Engineered Products, which provides consulting and engineering seminars on machinery and pressure vessels. Dr. Sofronas has authored two engineering books and numerous technical articles on analytical methods.

A portion of my consulting career involved investigating catastrophic type failures on machines, pressure vessels and structures in the industry.
During a heavy rainstorm, flooding occurred at a plant location that had never before flooded.
It has been a long time since I graduated with my engineering degrees, but I feel qualified to discuss them after many years in industry.

An article on “Remote training of personnel”1 is interesting and appropriate at this time of COVID-19. It outlines the difficulties in presenting remote training courses and suggests methods that can help.

In the practice of engineering, we sometimes wish for better hindsight or foresight.

Periodically, I receive questions from engineers around the world on why a piece of critical machinery is vibrating excessively.
A catastrophic failure is defined (for this article) as a failure where lives have been lost and human causes have been a factor.
When equipment fails, it indicates weak points and usually exposes the cause(s) of the failure.
Vibrating equipment can be machines, such as vibrating screens, conveyor pans or a combination of both, that are designed to transport, sort or dry materials.
When a vessel containing a flammable liquid under pressure (such as those in an LNG road tanker truck) ruptures and ignites, a vapor fireball explosion can occur.
