Demonstration of Remote Monitoring Technology for Cathodic Protection Systems: Phase II

摘要

Cathodic protection (CP) is used to prevent corrosion on many buried and submerged metallic structures such as underground pipes and tanks. Periodic testing is required to ensure proper CP system operation, but many Directorates of Public Works (DPWs) do not have sufficient resources to conduct such tests regularly. Several companies have begun manufacturing remote monitoring units (RMUs) for CP systems. The technology allows personnel to monitor multiple CP systems from a central location so problems can be detected and repaired immediately. RMUs from three manufacturers were evaluated during Phase I of this study (FEAP TR 97/76) to determine their effectiveness. Only one of them performed successfully. During Phase II, RMUs from two additional manufacturers were evaluated. Results showed that both of the systems from Phase II performed successfully and are suitable for use at Army installations.
