Abstract

We apply the Boundary Element Method to the Laplace equation for the electric potential in the region surrounding a pipeline. The resistivity effects are taken into account by means of the Kirchoff equation. The objective is the obtainment point by point of the pipleine cover resistance and the estimation of the electric current needed to meet the required protection criterion. 1 Introduction The subject of cathodic protection on buried pipelines [1][2] has only recently begun to be studied by means of advanced numerical techniques [3]. In other corrosion problems, such as those of cathodic protection of subma- rine structures (i.e., vessels, platforms) [4][5] or tanks [6], the numerical technique largely accepted is the Boundary Ele
