abstract
The antifouling technique through seawater electrolysis for ship hulls may be realized by an antifoul-ing system consisting of a power unit and the electro-conductive film. In the electric field formed bysuch an antifouling system, besides that both the electro-conductive film layer sub-region and the sea-water sub-region are included, polarization occurs on the interface between electro-conductive film layerand seawater. Therefore, based on the Interface Electro-Double Layer theory, a numerical simulationtechnique using both of the finite element method and the boundary element method jointly was devel-oped.An excellent efficiency of the antifouling system using electro-conductive film was demonstratedwith a long term antifouling test, and the validity of the developed numerical simulation method wasverified by its applications to a small size passenger boat, for which the antifouling system was under-taken and the antifouling efficiency test was performed.
