Summary:In this work, the idea of the impressed current cathodic protection CP method for metallic buried pipes is declared; then, the available theoretical background of the design of such a system is studied. Since all the available formulas of the CP system design are empirical and approximate, the numerical approach is considered using the Finite Element Method (FEM) to reach a more accurate description of the system behavior. The already existing cathodic protection CP system of the pipe used to transfer raw water from the Tigris River to Al-Quds Gas Station in Baghdad is considered as a case study. Using FE computer package ANSYS for this purpose suffers from meshing the model. A small-scale model of the system is considered to describe the operation and declare the analysis. A modified approach is suggested for designing such a system and achieves more accurate protection practically. A suggestion to improve the CP system of Al-Quds Gas Station is mentioned.
