CURRENT CATHODIC PROTECTION SYSTEM

Impressed Current Cathodic Protection ( ICCP ) systems use a transformer rectifier unit to feed a suitable low voltage current to the structure to be protected through strategically positioned inert anodes. For marine application, we makes self –regulating auto control units where a set of reference electrodes constantly monitor the potential of the structure and feed measurement to the control unit, which determines the appropriate amount of current to be fed to the structure to maintain the structure potential at level where corrosion with not occur.

 

We offers Platinized – Titanium and MMO-Titanium anodes and Zinc as well as Silver – Silver Chloride reference electrodes complete with cofferdam assembly shielding material.

Low – Signature warship ICCP systems

 

Any form of Cathodic protection or in its absence uncontrolled corrosion are accompanied by current flow in the sea water. Such current flows create associated electrical and magnetic fields that are detectable by suitable sensors and hence are known as signatures. While these are of no consequence to commercial vessels they are considered a significant mine-threat for front line warships. SARGAM has pioneered the introduction of low-signature ICCP systems for warships in the Indian Navy and has the largest number of such systems working in Indian warships. As an adjunct to such systems SARGAM has also introduced in Indian Naval ships Active Shaft Grounding Systems that use advanced electronics to ground the propeller shaft to the hull thereby significantly reducing the Extra Low Frequency Electro-magnetic signatures arising from ICCP current flowing through the propeller shaft. SARGAM was the first Asian company to manufacture this system.
