Paper presented at the CORROSION 2020, June 14–18, 2020
Paper Number: NACE-2020-14927
... ABSTRACT A close coupled mixed metal oxide (MMO) anode, grid or concentric ring, cathodic protection (CP) system is a state-of-the-art technique for corrosion prevention of the soil-side bottom of an aboveground storage tank (AST) resting on sand pads. The regulatory requirement of secondary...

... protection conditions after only 10 years. A retrofit was planned in 1987 using an impressed current system with LIDA TSA(?) 1 MMO anodes impressed current system, and the system was successfully commissioned in 1987. Protection conditions were achieved and continuously maintained from start-up for 18 years...
