<b>Electric cathodic protection / ICCP</b>
With external current protection, the monitoring of the corrosion protection on the underwater hull is easier. The automatically working, potential-controlled electrical corrosion protection system adapts to the respective condition of the underwater hull to be protected. The protection current strength depends on the electrolytic properties of the sea water, the condition of the outer skin and the conditions of the berth (stray currents through quays).
Impressed Current Cathodic Protection (ICCP) consists of anodes connected to a direct current power source, usually a transformer rectifier connected to alternating current power. In the absence of AC power, alternative power sources can be used. Anodes for Impressed Current Cathodic Protection (ICCP) systems are available in various shapes and sizes, commonly as tubular and solid rod shapes or continuous strips made of various materials. These include, high silicon cast iron, mixed metal oxide (MMO), niobium and platinum coated wire, and other materials.
