More than 30 Years of Experience and Specialization in Corrosion Protection and Anti-Fouling

K.C. has focused on design and production of corrosion protection, anti-fouling and such relevant equipment since its establishment in 1986. For the past 30 years, it has been able to have around 25,000 ships delivered. With these prominent quality and numerous supply references, K.C.

Ltd. is well-known to world-famous shipping and shipbuilding companies.

Thanks to the continued and valuable orders derived by the ceaseless R&D for high-quality products and the best services beyond warranty, K.C. has been able to erect excellent fi nancing stand on no liability. Not only that, but it has been building an excellent reputation for customer satisfaction as it manages continuous communication with clients beyond order delivery. Lately, it has been successfully expanding its markets to power plants or EPC of electric anticorrosion installations for nuclear plants while advertising its technologies.


The World’s Best System for Corrosion Protection, Anti-fouling and Shaft Earthing

Using an arrangement of hull-mounted anodes on Titanium and reference cells connected to automatic control panels, K.C.’s I.C.C.P. (Impressed Current Cathodic Protection) produces much more powerful external current to suppress the natural electro-chemical activity on the wett ed surface of the hull. This eliminates the formation of aggressive corrosion cells on the surface of plates and avoids the problems that can arise where dissimilar metals are introduced through welding or brought into proximity by other components such as propellers.


201610e_page_58_07An essential feature of K.C.’s I.C.C.P.system is that it constantly monitors the electrical potential of the seawater / hull interface and effi ciently controls the protective current to the anodes in relation to this. Therefore, K.C.’s system is much more eff ective and reliable than those of its competitors.

K.C. system is based on the electrolytic principle and consists of copper, aluminum and ferrous anodes that are fed with an impressed electrical current from a control panel. The anodes are usually mounted in pairs in the ship’s sea chest or strainer where they are in direct contact with the fl ow of water entering the seawater lines. Also the anodes can be mounted on an independent treatment tank for added convenience. In operation, the copper anode produces ions that are transported by the seawater and carried into the pipework system and equipment beyond.

A turning propeller shaft on a ship becomes electrically insulated from the hull by the lubricating oil fi lm in the bearings and by the use of non-metallic bearing materials in the tail shaft. When the shaft is insulated in this way, an electrical potential can be measured between the shaft and the hull, which can accelerate corrosion in the ship. If the ship has a system of cathodic protection, whether it is sacrifi cial anode or an impressed current system, the shaft insulation will prevent the propeller from protection.
