Anticorrosion

1. ICCP SYSTEM (Impressed Current Cathodic Protection System)

• ICCP 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 system work by supplying a controlled amount of DC current to submerged surfaces using highly reliable mixed metal oxide anodes and zinc reference electrodes. This electrical current, constantly monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it begins.

2. MGPS SYSTEM (Marine Growth Prevention System)

• The basic principle on which MGPS runs is electrolysis. The process involves usage of copper, aluminum and ferrous anodes. The anodes are normally fixed in pairs in the main sea chest or in such place where they are in the direction of the flow of water. The copper anode produces ions, which are carried away by water into the piping and machinery system which are enough to prevent marine life from settling. Due to the impressed current, the aluminum/ferrous anode produces ions, which spread over the system and produce a anti corrosive film over the pipelines, heat exchanger, valves, refrigeration and A/C unit etc, internally.

3. SED SYSTEM (Shaft Earthing System)

• Shaft Earth Device consist of potential monitoring panel, Slip ring of Silver/Copper alloy, High purity silver graphite brushes, Brush Holders and installation accessories. SED is installed on the intermediate propeller shaft and provides full Cathodic protection to the propulsion Shaft.
