WebICCP (Impressed Current Cathodic Protection) systems provide protection to a wide variety of vital and valuable equipment, vessels and structures onshore and offshore. Impressed current cathodic protection (ICCP) is a corrosion protection system consisting of sacrificial anodes connected to an external power source. WebOur ICCP systems can be provided for any size of vessel. A new design is now available for small, specialized craft, such as tugs, seiner, supply boats, ice breakers and FPSO, whose cathodic protection requirements can be more demanding and require specialized system.

WebSchematic figure of ICCP 14. The current has to flow in a loop and therefore the surface of structure that can be protected is the submerged surface that received protection current from anodes. 15 In case of inner pipe surface needs to be protected by CP, the anodes (usually ICCP anodes) have to be installed inside the pipe. WebThese standard ship corrosion protection systems were based on dry docking and coating system repairs scheduled for every three to five years. As a result, not many of these FPSOs exceeded 10 years of continuous operation. Studies show that the expense of over protection can start from around year 10.
