All over the world many of buried structures such as (storage tanks, pipelines and critical structures foundations) are suffering from soil corrosion problems which affect mainly the external surfaces of these structures. This paper emphasizes a model defining adequate CP technique including detailed design requirements in accordance with SABIC standards & specification, international codes and standards for the external bottom of newly constructed tank bottom. ICCP Ti-MMO grid system is one of important CP technique where can be used to protect aboveground storage tank bottom. A Ti-MMO anode grid system placed between an aboveground storage tank's bottom surfaces and the secondary High Density Poly Ethylene (HDPE) liner with properly distributed power-feeders connections can protect the tank's bottom plates against external corrosion. Such systems can achieve uniform potentials along the tank bottom surfaces.
