FAQ: Impressed current cathodic protection

An ICCP Impressed Current Cathodic Protection System, also sometimes referred to as an ICCP Impressed Current CORROSION System, is a means to protect metal surfaces exposed to water 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.

Unlike traditional sacrificial anodes, which lead to the release of heavy metals and metals such as zinc and aluminum alloys, and other anode materials, into the marine environment, ICCP systems are a far more environmentally friendly form of protection. In addition, impressed current methods of cathodic protection are enable users to monitor and adjust the level of protection at the touch of a button, and are a more economical alternative.

Impressed current protection is used to protect everything from large vessels to submerged metal structures. CORROSION was the first company in the world to develop impressed current corrosion protection solutions for the foundations of wind turbines in 2007.

We continue to be the leading impressed current cathodic protection company in the world for the wind energy sector, helping to protect thousands of offshore wind turbines worldwide.
