Book Description
The Army owns and maintains more than 3000 miles of buried natural gas pipeline, 20,000 underground storage tanks (USTs), and more than 300 elevated water storage tanks. Cathodic protection (CP) is required by regulation on many of these structures to prevent corrosion. 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. Many malfunctions remain undetected until the structure corrodes and leaks. Several companies have begun manufacturing remote monitoring units (RMUs) for CP systems. This technology allows personnel to monitor multiple CP systems from a central location so problems can be detected and repaired immediately. An 8 month field evaluation of CP RMUs was performed to determine the effectiveness of systems from three manufacturers. Demonstration systems were selected on the basis of cost, features, availability, etc. RMU readings were compared with manual method readings throughout a variety of conditions. Units from only one manufacturer performed successfully. New systems have entered the market since this demonstration began.

Book Description
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.

Book Description
Cathodic protection (CP) is required by Federal regulation or Army policy on many buried and submerged structures to prevent corrosion. Periodic testing is required to ensure proper CP system operation, but this testing can be time-consuming and many Army Directorates of Public Works (DPWs) do not have the resources to perform it. Several companies have begun manufacturing remote monitoring units (RMUs) for CP systems. These units allow DPWs to monitor multiple CP systems from a central location. Several commercially available units have been evaluated during a two-phase FEAP demonstration. Beneficial RMU features have been identified and lessons have been learned concerning their implementation. A FEAP User Guide (FEAP UG 97/75) was published based on the results from Phase I. This user guide provides updated information based on Phase II results.

Book Description
This project demonstrated and implemented emerging corrosion protection technologies for utilities at Fort Carson, Colorado, consisting of six deep anode impressed current cathodic protection (ICCP) systems, 106 drive-by type remote monitoring units for existing test stations, and 26 drive-by type remote monitoring units for existing and new rectifiers. ICCP rectifiers and groundbeds were installed on one natural gas main, one steam main, one water storage reservoir, and three separate water supply mains. The remote monitoring units have reduced the amount of time that it takes the contractor who maintains the ICCP systems at Fort Carson to obtain readings from 2 months to 2 days. The automated data are saved in a format that allows him to establish trends for early signs of problems with the system that needs immediate attention. Other Army and DoD Installations have experienced similar problems with the need to upgrade and maintain their cathodic protection systems. It is therefore recommended that these installations implement cathodic protection upgrades and remote monitoring technologies to extend the service life of the utility system.
