However, the area of bare metal exposed to the sea water contributes the most to current demand. The amount of current needed for a functional ICCP system depends on a variety of factors such as salinity and the temperature of the water. This ensures that the ship hull surface is protected from corrosion because the entire hull functions as a cathode. When using the ICCP method to protect the ship from corrosion, external currents are applied to convert high-potential anodic sites on a ship’s hull to low-potential cathodic sites.

Mitigating Ship Hull Corrosion with ICCP Ships like this one may utilize corrosion prevention systems to maintain structural integrity. Instead of trying to fix these issues after the fact, which can be costly, you can focus on avoiding corrosion before it happens with protection methods, such as ICCP. This may result in leakages and unsafe working conditions. This causes oxidation and corrosion in the anodic areas.Ī simplified image showing an anode and cathode within an electrolyte solution.Ĭorrosion causes structures like ships and oil platforms to deteriorate and weaken. Put simply, the ocean is an electrolyte that facilitates a flow of electrons from an anode with a higher electrolyte potential to a cathode with a lower electrolyte potential. The corrosion you see on a ship’s hull occurs when there are areas with different potentials within an electrolyte - ocean water, in this case. But if you were to dive beneath the waves, you might observe one of the biggest problems ships face: corrosion. Sitting on the deck of a ship, you may be unaware of everything occurring underneath you. Here, we use simulation to investigate how coating a propeller affects ICCP efficiency. The efficiency of this method depends on factors such as the use of a coated propeller. One such system, impressed current cathodic protection (ICCP), mitigates corrosion by applying an external current to a ship hull. ![]() These utilize different tools, such as sacrificial anodes or impressed currents, to help maritime-based industries stay afloat. Avoiding corrosion in a harsh ocean environment often requires the use of cathodic protection methods.
