I.C.C.P System

Corrosion of hull steel plate in seawater is a kind of natural electrochemical reaction.The hull impressed current cathodic protection device can effeictively prevent the corrosion of the water immersion part of the hull.

a.With the change of the ship's working conditions(Speed,coating and sea water) automatic regulation of the protection of the current.
b.The surface roughness of the hull is suppressed or reduced,and the fuel consumption is reduced.
c.Reduce the electrochemical corrosion of the rudder and propeller.
d. Prolong the dock repair cycle,improve the efficiency of shipping.
e. Applicable to all sizes of ships.

The impressed current cathodic protection is by means of direct current power supply (constant potential instrument), which is protected by the application of the auxiliary anode which is installed on the hull to protect the hull. The system has been widely used in various types of ships and offshore oil drilling platforms,pipelines,whart steel piles, etc., Have achived good results of protection.

The impressed current cathodic protection system is composed of constant potential instrument,auxiliary anode and anode shield layer,reference electode,rudder and propeller shaft grouning device.
a. Auxiliary anode. Used a s a current output,which is almost insoluble in itself.Small volume,light weight,large discharge capacity,long life.
b.Reference Electrode Potential of a protected body as a reference.Stable,accurate,sensitive and robust.
