A STUDY ON CAD OF ANTIFOULING SYSTEM BY SEA WATER ELECTROLYSIS (REPORT 1 DEVELOPMENT OF THE ANALYSIS METHOD FOR THE POTENTIAL FIELD)

An antifouling system for ocean structures by sea water electrolysis has been developed. In the system, the CIO- ions effective for antifouling is generated by the sea water electrolysis reaction taking place by electric current supplied from the electro- conductive coatings on the surface of the structure. In order to design the antifouling system, the current density on the surface of the electro-conductive coatings should be estimable. In this paper, a numerical method by FEM is developed for the analysis of the potential field including electro-conductive coatings, sea water and the electric double layer formed on the coatings-water interface. The electric behaviour of the electric double layer is included in the polarization characteristics. In order to treat the unknown potential distribution on both sides of the electric double layer, plate elements with double nodal points are employed for the discretization of the coatings-water interface. The validity and usefulness of the proposed method are confirmed with experimental results and by the numerical simulations of some antifouling models.
