Abstract: Cathodic protection mostly used to protect buried structures of oil and gas pipes in oil and gas industries from corrosion. Cathodic protection by impressed current method includes the formation of an electrolyzed system in which anode and cathode is obtained by direct current generator. installing one or more anodes of cast iron adjacent to a structure and the structure and the anode(s) are connected respectively to negative and positive poles of the supply. In the present study, by collecting actual soil data of the region, mechanical specifications of oil transfer pipes and their coating in Ahwaz region and also using available calculations and manuals regarding types of anodes and solar panels and batteries in the market a region-specified solar Cathodic protection method was designed. By calculations, the best type of solar panel (AT-50), number of panels and their voltage and produced current were obtained 42, , 52.2V and 40.04 A, respectively. The proposed battery is sealed lead acid type with number, voltage and current of 4, 48V and 250 A, respectively.
