What is the most common component to fail on your compressors? 

If you are like most, it’s the suction valves, but as shown in the accompanying chart, there are any number of other parts that fail as well. Unfortunately, when one part fails, it can quickly lead to more failures or a catastrophic crash. A failed set of rings or rider bands can lead to a discharge valve failure which can, sometimes in a matter of seconds, wreck a crosshead pin bushing, and it goes on from there. 


Most likely, if you’re reading this newsletter, you know us at MMS. We’re bunch of old guys that collectively have over 250 years in the engine/compressor business. We are especially pleased to report that Warren Laible, our Subject Matter Expert, has agreed to write a few paragraphs periodically to explain the “how’s and why's” of many of these failures. What we hope to do is share his considerable knowledge through a column in this newsletter, authored by the “Compressor Professor”.


As you know, we have built our Sentinel®- CPM Diagnostics System around Warren’s Multi-Factor Diagnostic Algorithms, but there’s no substitute for an explanation of the inner workings of an analyst’s mind; it is what he sees on the PV or PT curve, etc. that suggests the anomaly that is occurring. As we’ve stated on numerous occasions however, our Diagnostics will not replace a good analyst, but it will significantly reduce his windshield time. 


We hope you enjoy the column and look forward to hearing what you think.

Back to Basics

Warren Laible, SME

MMS, LLC

The Compressor Professor


Let me introduce myself. My name is Warren Laible, I am 76 years old and I have a bit of experience with reciprocating gas compressors. I'm sitting at my desk in Wylie TX and my left knee hurts something horrible, so I am having a little bit of difficulty trying to explain myself properly. I think the pain in my knee is probably related to some kind of engine room injury back when I climbed around on oily engines and compressors with a portable analyzer trying to collect data. In addition, the heat and noise associated with that environment probably damaged my hearing and taken a few years off of my life. However, I enjoyed it, and would do it again if I had the physical ability, but unfortunately I don’t. 

I prefer not to waste the knowledge that I have gained as a gear head and analyst so I will be presenting a series of articles on my favorite subject: reciprocating compressor mechanical condition and performance analysis. I was fortunate in working with, and knowing some of the best analysts, engineers, technicians, and managers in the industry. In addition to their teachings and mentorship, I gained a lot of useful knowledge from the mistakes that I made. As I made lots of mistakes, I learned a lot, a whole lot, really a whole lot. 


Over the years, I have been given many nicknames, monikers, and titles, some of which I will list here. This list has been edited slightly to remove some of the more colorful names. OK, here it goes, student, auto mechanic, graduate, friend, husband, cadet, Lieutenant, daddy, Captain, commander, veteran, truck mechanic, engine/compressor mechanic, contract analyst, company analyst, product support manager, grandfather, tech services manager, tech services director, instructor, old fart, retiree, great grandfather, widower, subject matter expert, and compressor professor.


Whenever there was a conflict between the manufacturer or supplier and the customer, I always tried to side with the piece of equipment I was testing. It's all about integrity. Over the next several newsletters I will be discussing the compression process, suction valve defects and leakage, discharge valve defects and leakage, ring defects and leakage, and leaks into the atmosphere or surroundings. 

If you have questions or comments or examples that you want addressed in these articles, a link will be provided.


Regards,

Warren, AKA Compressor Professor

Safety First 


The Oil and Gas Industries Fall Fatality Statistics


Falls are one of the most common hazards in our industry. They can occur in all areas of our industry, from engine rooms, offshore rigs, pipelines, to right in our own home. Falls can be fatal. Falls are the leading cause of death and the second most common cause of non-fatal injuries in the oil and gas industry. According to the CDC they account for more than 30% of all fatalities and account for almost 20% of all reported injuries. 


We are all challenged with protecting ourselves and our teams from falls. Our work is fast-paced and often physically demanding. A moment to stop and think about putting safety first can prevent an accident. 

  • Remember to slow down and use the handrails on steps and ladders when there is water or oil is present on the floor.
  • Remove trip/fall hazards such as tools, equipment, and debris.
  • Use proper safety equipment.


Some teams use the self-checking tool STAR (Stop, Think, Act, Review) before each physical action is performed. Self-checking can keep us in the present and identify issues before they occur. It can become a habit and part of our routine to ensure our safety on the job and at home. 


S - Stop - Take a moment to assess the situation and your personal safety

T - Think - Do I have everything I need for the job?

A - Act - Complete the work

R - Review - Did everything go as planned? Is there anything I will change in my process in the future? 


Let us know if you have suggestions for safety tips we can share with our teams.
