E&S Grounding Solutions provides CDEGS-based cathodic protection design and corrosion control engineering for pipelines, petroleum storage terminals, LNG facilities, electric power substations, solar farms, data centers, military installations, and industrial plants.
Standard cathodic protection calculators use a single soil layer and calculate only the pipeline current demand. At a typical petroleum storage terminal, the copper grounding grid represents 4,053 milliamps of total current demand — 99% of the total — and standard calculators do not calculate it at all.
E&S uses CDEGS — Current Distribution, Electromagnetic Fields, Grounding, and Soil Structure Analysis — on every project. CDEGS resolves unlimited soil layers, accounts for every bonded metallic structure, evaluates every electromagnetic interference source, and computes step and touch voltages per IEEE 80-2013.
The E&S five-step process includes: onsite Wenner four-pin soil resistivity survey and RESAP multi-layer soil model; complete structure inventory; full current demand analysis per NACE SP0169, API 651, and IEEE 80-2013; interference and hazard analysis for stray DC, AC induction, and fence line coupling; and a PE-stamped design report.
Based on a real petroleum storage terminal scenario, a $18,500 E&S CDEGS analysis prevented a $943,150 pipeline failure event — a 51× return on investment. Corrosion costs the United States approximately $1.1 trillion annually.
Standards applied include NACE SP0169, API 651, IEEE 80-2013, NACE SP21424, ISO 18086, ASME B31.8, 49 CFR Part 192, 49 CFR Part 195, and NACE SP0572.
Every E&S corrosion control project is delivered as a signed and sealed engineering report by a licensed Professional Engineer, defensible before PHMSA, the EPA, the DOT, and state pipeline safety offices.
