Abstract
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.
Keywords: cathodic protection, mathematical simulation, boundary element
method, electric and magnetic field.
