Pipeline Corrosion Protection Using Impressed Current Cathodic Protection

Application ID: 115451

In this example, three parallel pipelines of length 68 km and a horizontal separation distance of 10 m between them are protected against corrosion by an impressed current cathodic protection (ICCP) system using a series of anodes.

Each anode is connected to all three pipelines, demonstrating a one-to-many connection modeled by the Impressed Current Point feature and by Connection Point and External Short point subfeatures of the Edge Electrode feature.

The model considers two layers of soil of different electrolyte conductivity. The electrode potential and the total interface current density are plotted along the length of the pipelines to evaluate if they are adequately protected against corrosion.

This model example illustrates applications of this type that would nominally be built using the following products:
