This paper presents a 3D software tool for the design and optimization of cathodic protection systems for submerged structures. It provides the corrosion engineer an intelligent tool for managing operational costs, significantly reducing expensive commissioning surveys and costly repairs, adding major value to the cathodic protection business.

A Finite Element Model (FEM) is used to solve the potential model taking into account ohmic drop effects in the electrolyte and cabling and non-linear polarization behaviour at both the cathode and anode. From the resulting potential field in the seawater electrical and magentic signatures can be obtained.

In this paper several examples will be presented including oil platform, ballast tank and a marine vessel for which the ICCP has been optimized in order to minimize the underwater electrical potential and corrosion related magnetic signature.
