CP testing of Fiberglass Underground Storage

The following is a conversation between a Washington state regulator and Cal Chapman about corrosion protection for underground fiberglass tanks.

Initial Question:

CP testing of Fiberglass Underground Storage Tanks – a Washington State regulator in field, asking for help in data interpretation:

I'm baffled here folks. I was inspecting an UST yesterday and found they were behind on CP testing. I opened the sump and found what appeared to be an Owens Corning fiberglass UST. The last test was good. I tested for continuity and protection. All meet criteria. Has anyone tested a fiberglass tank and got acceptable CP results? What is the cause of this? Most likely there is a metal strike plate inside the tank, which is where I made contact. Thanks.

External Corrosion of Pipelines, Bulk Tanks, and Other Metal Structures in the Eagle Ford Shale

The Eagle Ford Shale region of South Texas has been booming with a huge amount of oil and gas exploration, construction of infrastructure, and massive job creation. Similar things are happening in other Texas oil shale plays such as the West Texas Sprayberry, Wolfcamp, Cline, and Haynesville.   Similar booms have been happening in the Bakken of North Dakota and Montana, Niobrara/DJ Basin in Colorado, the Marcellus and Utica in Ohio, Pennsylvania and West Virginia, and other successful oil and gas plays.

Chapman Engineering Corrosion Protection

The Eagle Ford Shale has been very active in terms of oil and gas exploration since 2009-2010.  Pipelines have been installed in record time.  The metal pipe has a corrosion protection coating on its exterior.  Many times this coating gets nicks in it during installation.  These nicks can cause rusting pits into the pipe wall over time.  It’s possible for a pit to go completely through the wall, and then there’s a leak.  Sometimes the integrity of the welds that hold sections of pipe together is not quite right, and it’s possible that the coating over welds is not applied the right way.  These problems can cause severe corrosion over time as well.

Due Diligence - Interesting "Phrase" But What Does It Mean?

Last month at the Texas Eagle Ford Shale Expo in Corpus Christi, I heard several discussions about big assets changing hands. Thanks especially to my environmental engineering background, I have many times worked with real estate professionals, attorneys, and developers, on big commercial deals where “due diligence” was being performed. What is “due diligence?”

What Does It Cost Not to Inspect New Construction?

As I wrote in the previous issue, the Eagle Ford Shale development is causing a huge construction boom in infrastructure, pipelines, and plants. Our business is in the corrosion protection and environmental compliance, assessment and cleanup industries. It’s difficult to admit, but most of the problems we are asked to solve can be called “self-inflicted wounds!”
