300A Marine Iccp Hull Corrosion Protection System with Mmo Anode

ICCP Hull Corrosion Protection System

 

Basic Principle

During metals corrosion in water, we could see a distinctive feature in its mechanism, i.e. corrosion takes place in anodic area instead of the cathode area.
Cathode protection with impressed current makes use of this principle to protect the surface of ship iron and steel. By means of applying protective current to the iron and steel to be protected, the cathode will be polarized and the current will be larger, the electron will be accumulated more and more on the cathode surface, and the negative potential value will be added. When the potential reach a certain degree, the iron and steel surface will reach equal potential, and the micro battery of corrosion disappears. Meanwhile, the iron and steel corrosion is inhibited. The cathode protection with impressed current for ship body is an anti-corrosion technology using DC power equipped on the ship, and auxiliary anode assembled on the ship to apply protective current to the ship body, which then becomes cathode for protection.

System Advantage

• Increased life of rudders, shafts, struts and propellers as well as any other underwater parts affected by electrolysis
• Anodes are light, sturdy and compact for easy shipping, storage and installation
• Anodes, reference cells and automatic control systems maintain just the right amount of protection for underwater hulls and fittings, unlike standard zinc anodes, which can't adjust to changes in salinity or compensate for extreme paint loss
• Automatic control equipment ensures reliable, simple operation
• Optimum documented corrosion protection at minimum overall cost
• Only one installation required for the life of the vessel or structure
• Increased dry-dock interval
