Abstract Cathodic protection is most frequently used technique for protection of underground or underwater metallic infrastructures from corrosion. Design of the cathodic protection system implies determination of the electric potential and current density distribution on the electrode surfaces. These values must meet criterions defined by relevant standards. For the calculation of the electrical potential and current density distribution, different analytical and numerical methods can be used. In this paper, a review of the methods that are used for calculate of the cathodic protection system parameters is given. Also, due to frequent use, a mathematical model based on the boundary element method for the calculation of the cathodic protection system parameters is presented in more detail. Presented mathematical model was used for calculation of the cathodic protection system parameters of one geometry simple example.
