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.

The software is entirely CAD integrated, offering a user-friendly interface for the CP design, including file import from numerous other CAD packages. The key model features include amongst others:

  • parameterization of all geometrical dimensions

  • simulation of 3D CP-configurations with arbitrary complexity

  • interference from 3rd party CP-systems

  • ohmic drop effects in the electrolyte

  • anodic and cathodic reaction polarization behavior

  • impressed current and sacrificial anodes

  • effect of cabling (ohmic resistance along cable, effect of cable breakdown, …)

  • varying electrolyte resistivity

In this paper, the protection level of a hypothetical marine vessel using impressed current cathodic protection (ICCP) systems will be investigated. In addition, the underwater electric potential (UEP) of the vessel will be calculated.
