Demonstration of Cathodic Protection Systems for Utilities in Severely Corrosive Environments at Fort Jackson

Abstract

This project demonstrated and implemented emerging corrosion protection technologies for utilities at Fort Jackson, SC. These consisted of three deep anode impressed current cathodic protection (ICCP) systems, 100 drive-by-type remote monitoring units (RMU) for monitoring the cathodic protection on the buried gas lines, and a new cathodic protection system in the elevated water storage tank, providing complete and uniform protection in the tank interior below the water line. The CP system in the water storage tank is also equipped with remote monitoring capability. The remote monitoring units have reduced the amount of time that it takes a trained technician to collect the data from about a week to only about 3 hours. The CP data collected from the drive by RMUs are collected and stored on a laptop computer for use in different analysis, including transfer into an Excel spreadsheet where it is automatically analyzed on a pass/fail basis.
