Cathodic protection is a method for preventing corrosion on submerged and underground metallic structures. Cathodic protection is one of the most effective methods for preventing corrosion on a metal surface. Cathodic protection is commonly used to protect numerous structures against corrosion, such as ships, offshore floaters, subsea equipment, harbours, pipelines, tanks; basically all submerged or buried metal structures. The technique is based on convertering active areas on a metal surface to passive, in other words making them the cathode of an electrochemical cell.

Galvanic corrosion is the number one enemy to any construction in seawater. All the time. And tailor-made. We can follow, maintain, and fix issues from shore. Extensive checking and control options are directly connected to the vessel management system. We can constantly monitor data with our ICCP cathodic protection system.
Even when water conditions change, our system adapts. It continually provides the correct and the best protection. Our technology ensures the right protection for your asset. In every situation. Precisely fitted to your maritime demands. Our ICCP systems offer even more benefits. But ICCP has even more advantages over sacrificial anodes.
The service life is also long—25 years. Designed and developed by: Reboot in cooperation with Nivo. Necessary cookies are absolutely essential for the website to function properly. This category only includes cookies that ensures basic functionalities and security features of the website.

Impressed Current Cathodic Protection
The application of sacrificial anodes is a passive protection method that doesn't accommodate for changed circumstances such as coating damage. Their volume is also calculated for a specific lifetime, after which they need to be replaced. The reference cells measure the underwater electrical protection potential and based on this data, the power unit regulates the required output to the anodes. The resulting impressed current prevents the corrosion process from taking place. These advanced systems allow for real-time monitoring and guarantee the required protection level at all times. A correctly installed, operated and serviced ICCP system can function for 25 years or more.
Impressed current cathodic protection systems are the ultimate state-of-the-art, long-term solution to corrosion problems, and are recognized as a superior alternative to sacrificial anode systems, which require frequent replacement. Impressed current cathodic protection systems are preferred by ship owners because they reduce fuel cost and maintenance. This electrical current, constantly monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it begins. Refer to information below for detailed specifications. This control is obtained by inserting a third electrode between the anode and the cathode. Zinc Reference Electrode.
