The purpose of present work is to design an impressed current cathodic protection system (ICCP) to protect 11 uncoated steel tanks partially buried in a soil with a resistivity of 600 ohm.cm with varying content temperatures and surface areas, located in Petronas Portsudan bulk depot (P.S.B.D.). A study was carried out to the previously installed system and it was found that it was faulty. The scope of work included the design and determination of all necessary materials of ICCP of tank bottoms utilizing Silicon cast iron anodes. The results showed that the cathodic protection system requires a total of 25 anodes with a 3.6 Amp current output per anode, distributed as shallow horizontal groundbeds according to the tank’s current demand. The groundbeds are located 3 meters deep and 3 meters away from the orifice ...
