Abstract
In order to overcome the shortcomings of traditional electric dipole modeling which cannot reflect the distribution of shaft-rate electric field and hull potential in the impressed current cathodic protection system (ICCP), the hull and propeller material, hull surface coating, the number and position of the anodes for ICCP are modeled based on COMSOL multi-physical field coupled finite element method. Dirichlet boundary condition is used to numerically calculate the distribution of the shaft-rate electric field at the 20 m plane underwater under breaking away ICCP switch conditions. The simulation results show that the influence of the protection current of ICCP on the potential distribution of hull and the shaft-rate electric field distribution can be calculated by using the multi-physical field coupled finite element method. When the protection current is set reasonably, it can restrain the corrosion of ship hull and the shaft-rate electric field.
