The concept of reducing Condition Monitoring Locations (CMLs) is misguided, and the number and location of CMLs should be OPTIMIZED, not systematically reduced. CML allocation in piping requires a good process, otherwise, you can run into a lot of dead ends before arriving at your intended destination.

OSHA Communication Rules Can Help Control Corrosion

By Nolan L. Miller at SASOL North America, and Marc McConnell, P.E. at Versa Integrity Group

If we could measure, understand, mitigate, and most importantly, control corrosion, we can do a better job of keeping the product in the pipes. To accomplish this task, we needed to know what is causing the corrosion and how to control it.

By Marc McConnell, P.E. at Versa Integrity Group, David Jordan at CVR Energy, and Grady Hatton at Versa Integrity Group

Is Your Killed Carbon Steel Resistant to  High Temperature Sulfidation?
March/April 2014 Inspectioneering Journal
By Marc McConnell, P.E. at Versa Integrity Group, Gerrit M. Buchheim, P.E. at Becht Engineering Co., Inc., and Josh Yoakam at Holly Refining and Marketing - Tulsa, LLC

High temperature sulfidation is probably the most well- known corrosion mechanism in the oil refining industry because it occurs in large sections of the refinery.

A Discussion on Hydrogen Bake-Outs
January/February 2014 Inspectioneering Journal
By Marc McConnell, P.E. at Versa Integrity Group, Josh Yoakam at Holly Refining and Marketing - Tulsa, LLC, and Frank Dean at Ion Science, Ltd.

This is the second of two articles published in Inspectioneering Journal discussing the value of hydrogen bake-outs. Our first article was published in the May/June 2013 issue and received a great response from the Inspectioneering community. In this piece, we will continue the discussion and touch on some new technologies used to enhance the bake-out process.

At PinnacleAIS, we often get requests for a Senior API Inspector. But what does that mean exactly? What qualifications are required? Is there a test or a certification that provides the end user with assurance they are getting a higher caliber inspector or inspection service? Often there are different ideas of what comprises a "Senior" Inspector.

Who at your facility “owns” injection point hardware? Typically, injection point hardware falls into the “Gray Zone”.

The Hype about Hydrogen Bake-Outs!
May/June 2013 Inspectioneering Journal
By Marc McConnell, P.E. at Versa Integrity Group

With 30 years of refinery experience, I have been through many turnarounds and been involved with a lot of repairs. When I started in the business, we would have inspectors that “owned” their specific pieces of equipment.
