Numerical analysis of potential distributions in consideration for influence of some parameters of seawater in floating structures under cathodic protection using sacrificial anodes is difficult, because of complicated relation between mechanism of corrosion and parameters of seawater. This report has discussed with usefulness of numerical analysis with potential distribution using Neural Network Method in consideration for influence of parameters of seawater. First, polarization characteristics of electrodes in consideration for influence of parameters of seawater has been estimated by Neural Network method. Polarization characteristics of electrodes have been assumed to be linear. Second using presumed polarization characteristics as input value a change of potential distributions has been estimated by Boundary Element Method year by year. From these results, the necessity of anticorrosion design in consideration for influence of parameters of seawater have been confirmed.
