WebDec 18, 2024 · It is also a popular method for retrofitting corrosion protection systems in offshore oil platforms due to the high current output and ease of installation. One major drawback with ICCP is that the current output may be large, yielding very negative polarization of the metal surfaces nearby. WebNov 16, 2024 · For these reasons, galvanic corrosion often attacks ship hulls, offshore rigs, and oil and gas pipelines. Cathodic protection works by converting unwanted anodic (active) sites on a metal's surface to cathodic (passive) sites through the application of an opposing current. This opposing current supplies free electrons and force local anodes to ...
