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.
