<P>PROBLEM TO BE SOLVED: To prevent the service life of a positive electrode from becoming shorter than design, when becoming insufficient for a required electric current in an undersea part, and when using a sacrifice positive electrode, in an oceanic structure for performing electric protection. <P>SOLUTION: The electric protection of an oceanic steel structure is performed by an electric current value of adding an electric current value provided by multiplying this value by a factor 1.0 to 2.0, by multiplying an anticorrosive current value with the undersea part of an average low tide surface or less of the oceanic steel structure by the same current density as the undersea part in the object area of a range of a synodical average high tide surface from the average low tide surface. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
