The first Grid system for cathodic protection of aboveground storage tank (AST) bottoms was energized in 1989. This paper examines how the system is performing 30 years later. Design, system commissioning and long-term performance data are reviewed. Tank pad materials and current densities for protection at both ambient and high temperatures are discussed. The performance of individual system components is examined including ribbon anodes, conductor bars, electrical connections, power feeds, reference electrodes and power supplies. The economics of alternative tank bottom cathodic protection system configurations for new tanks are discussed. System limitations are identified. Conclusions are presented as to the effectiveness and optimal configurations for tank bottom protection that will assist with designing proper protection systems for new-build installations.

Key words: cathodic protection, aboveground tanks, AST, tank bottom protection, Grid system
