An oil rig structure immersed in seawater is protected by 52 sacrificial aluminum anodes. Before deploying the anodes, the Corrosion Module is used to optimize their positions for the best possible corrosion protection. Visualized is the electrolyte potential on the surface of the structure.
The Corrosion Module empowers engineers to simulate the electrochemistry of corrosion and corrosion protection of metal structures. Models in 1D, 2D, and 3D are set-up to include the relevant corrosion and other reactions within the electrolyte and at the metal surface interface using a series of pre-defined user interfaces. These are solved while considering the transport of ions and neutral species in the solution, the current conduction in the metal structure, and other phenomena such as fluid flow and heat transfer.
Simulations using the Corrosion Module can be used to understand and avoid corrosion situations, as well as to design and optimize corrosion protection. This can be done at the microscopic scales, such as in crevice and pitting corrosion where the localized concentrations can be significant parameters in the charge-transfer reactions, or at larger scales, where the placement of sacrificial anodes around a structure is the goal of the simulation. In some cases, linking the simulations at both these scales is necessary and also achievable with the Corrosion Module.
