CathSense® ICCP for underwater hull protection

CathSense® ICCP system is designed to give predictable corrosion protection and low maintenance cost for 15-25 years.

CathSense® ICCP material package

CathSense® ICCP system has the ability to cathodically protect the underwater hull of virtually any vessel, regardless of size and coating condition.

The CathSense® ICCP package consists of control panel in cabinet, ICCP anodes and reference cells with cofferdams.CathSense ICCP item package

Disc anodes and reference electrodes are mounted in specially adapted cofferdams, welded below the water line, typically arranged as illustrated below. See the full range of ICCP products.

CathSense® –  designed to fit future demands for ship systems

ICCP explained

Impressed current cathodic protection (ICCP) systems have the benefit of an external power source to impose protective current. This makes it possible to protect any submerged structure, regardless of size and current requirement, by using long life anodes and appropriately sized power supplies. You may also want to read about design of corrosion protection for ships.

The most important feature of an ICCP system is the ability to continuously monitor the level of protection and adapt to the current required to avoid corrosion. Learn more about the principles of cathodic protection.

Vessels less than 140 m

Recommended ICCP arrangemetn for most offshore supply vessels, multi purpose vessels, fishing vessels and tugs:

Larger vessels

For vessels longer than 140 m, two ICCP systems should generally be applied to ensure even distribution of the protective current along the underwater hull. Typical system set up:

Large ship with impressed current cathodic protection (ICCP) and illusion of protective current distribution
Larger ship with double set of impressed current cathodic protection (ICCP) system.

ICCP spares for most common makes and models

Spares and equipment for most common ICCP makes and models are available from our stock points. See the full range of ICCP products.

MasterCath® – remote access software

MasterCath® works by pairing a remote computer with CathSense® ICCP control panels onboard the vessel.

The software provides an intuitive dashboard with real time operational values, alarm detection and several other useful features.
