In the Permian basin of West Texas, a supermajor’s high producing facility endured a catastrophic failure and turned to PC&S to assess and solve their volatile corrosion problems.
During risk assessment procedures we learned there was no cathodic protection of the Soil Side Bottom (SSB) of their Aboveground Storage Tanks (AST) and took all steps necessary to seal and protect the tanks using a Vapor Corrosion Inhibitor (VCI), i.e., provide access for the corrosion inhibitor and seal out the elements.
We then monitor VCI levels to ensure continued effectiveness and reapplication needs. To mitigate additional failures, we reassessed how they protect their assets from corrosion at all facilities and created a new standard for the protection of all ASTs.
