Abstract

This paper is analyzed the numerical model of cathodic protection, and its application in the damage of submarine pipeline coating. On the basis of the Laplace equation, combined with the boundary conditions required for the damage of the submarine pipeline coating, construct the numerical model that suitable for the damage of the submarine pipeline coating under cathodic protection. In this paper, the cathodic protection potential distribution of the submarine pipeline can be obtained by taking different values of the apparent resistivity of the coating in the boundary condition. The numerical model can be calculated by computer software using the three-dimensional finite element method. And then, analysis the applications of numerical model in the submarine pipeline corrosion combined with its damage rate.
