ICCP for harbours
Corrosion of steelworks is difficult to predict both when designing new harbour structures and when estimating remaining service life of existing structures.
CathSense® ICCP material package
CathSense® ICCP system has the ability to protect sheet piling and tubular support piles against corrosion, regardless of size and depth.
The CathSense® ICCP package consists of control panel in cabinet, ICCP anodes and reference cells.
The CathSense® control panel can be connected to any kind of ICCP anodes and reference electrodes, and includes the following features:
- High efficiency
- Flexible system with expandable output effect
- User-friendly operation
- Automatic logging
- Prepared for remote control and monitoring
Different ICCP anodes may be used for harbour protection. Most commonly used are MMO/Ti rod and FeSi rod anodes. See the full range of ICCP products.
CathSense® – designed to fit future demands for harbour systems
MasterCath® – remote access software
MasterCath® works by pairing a remote computer with CathSense® ICCP control panels installed for harbours.
The software provides an intuitive dashboard with real time operational values, alarm detection and several other useful features.

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 harbours.
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 stop corrosion. Learn more about the principles of cathodic protection.

Anode capacity
ICCP anodes are either inert (no inherent power) like the mixed-metal-oxide (MMO) coated titanium rods, or they are semi-intert like the silicon/chromium/iron (FeSiCr) rods. MMO coated anodes have a capacity typically between 50 and 100 A each, whilst the FeSiCr anodes generally have less than 30 A capacity each.
Allowance for metal loss
It is generally most rational that sheet piles are designed for being cathodically protected on the sea side, but dimensioned with allowance for metal loss on the shore side. An ICCP system can also be arranged for corrosion protection of internal steel surfaces exposed to backfilling.
