FAQ: ICCP Anode System

An ICCP system or ‘Impressed Current Cathodic Protection’ anode system, is a means to protect metal surfaces exposed to water [and oxygen] from CORROSION.

ICCP anodes are connected to an external power source. This provides the current that leads to the electrochemical reaction required for cathodic protection to take place.

The size and shape of ICCP anodes depends on the surface that they are utilized to protect, from large vessels to submerged metal structures, such as wind turbine monopiles.

ICCP anodes represent the most environmentally friendly solution to protect against galvanic corrosion because they do not lead to heavy toxic metals, such as aluminum and zinc alloys dissolving into the water.
