In this paper, the protective effect and distribution of the magnetic field of cathodic protection (CP) systems designed by experience were calculated by the boundary element method (BEM), and the calculation results had agreement with the measured results when the ship berthed at port, which suggested that calculation results are accurate. The performance of the CP system was optimized by moving the position of the anodes, as well as changing the output current of the anodes. The objective was to design the system to minimize the electric and magnetic field and provide adequate protection. Calculation results show that when the anodes were symmetrically installed at the 130th frame and the 232nd frame, the corrosion related magnetic field and total output current were reduced by about 40% and 8.6% respectively.
