ICCP

MARELCO™ ICCP HULL PROTECTION SYSTEM (IMPRESSED CURRENT CATHODIC PROTECTION)

For larger structures such as a Hull of a ship, the impressed current is evenly distributed over the entire wetted area of the Vessel. The ICCP System will give adequate corrosion protection to the hull of a ship over the life of the vessel in conjunction with a compatible protective coating system.

Copper and Aluminum anodes cannot economically deliver enough current to provide protection. In these cases, Impressed Current Cathodic Protection (ICCP) systems are used. These consist of anodes connected to a Control Panel that distributes impressed DC power to the Anodes. ICCP systems are only used where Corrosion protection is required, ICCP does not stop Marine Growth.

Cathodic protection reference electrodes are custom manufactured and placed strategically along the Hull. They provide remote monitoring and control of the protection parameters. The output of the ICCP system is optimized to provide enough current to provide protection to the Hull. Our ICCP systems are often designed with multiple independent zones of anodes with separate Cathodic reference electrodes. ICCP can be used for Shaft Grounding preventing spark corrosion in bearings and gear boxes.

DIFFERENCE BETWEEN A MGPS AND AN ICCP SYSTEM

  • Anodes located on the exterior hull of the vessel and used in conjunction with reference cell.
  • The anodes are wired through the hull to a control panel and the rudder has a slip ring assembly.
  • The Ship’s Hull is neutralized to prevent corrosion only.
  • Does not provide Marine Growth Protection.
