What is ICCP? The Gold Standard in Marine Corrosion Protection

Our systems work by supplying a controlled amount of DC current to submerged surfaces using highly reliable mixed metal oxide anodes and zinc reference electrodes. This electrical current is constantly monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it begins.

For more than 25 years, sea-going vessels of every type and size — oil tankers, LNG carriers, cruise ships, pleasure craft, workboats, semi-submersibles, and more — have benefited from the 24-hour protection provided by our ICCP systems against the costly, corrosive effects of electrolysis.

Typical System Components

Our ICCP systems consist of three main components working together to provide comprehensive corrosion protection.

Reference Cell / Electrode

ICCP systems are controlled to assure optimum protection. This control is obtained by inserting a third electrode between the anode and the cathode. The third cell/electrode is insulated and does not receive any anode current.

This cell/electrode is freely corroding and becomes the starting point — or reference — in eliminating corrosion. Zinc Reference Electrodes are used exclusively with our ICCP systems.

Power Supply Units & Control Panel

Power Supply Unit / Control Panel

Each standard ICCP system utilizes a solid-state controller which monitors and controls the protection as measured by the Zinc Reference Electrode. Anode current automatically increases when the electrode potential falls below the designated control value.

An over- and under-potential alarm is provided with the system package. We also offer optional digital control, state-of-the-art technology with every system.

Mixed Metal Oxide Anodes

Mixed Metal Oxide (MMO-Ti) anodes are used exclusively for our ICCP systems. ICCP anodes are manufactured in Linear Loop, Elliptical and Circular designs with insulating holders.

They are available in a single unit capacity of 75 to 225 amperes, as required for various installations.

Frequently Asked Questions About ICCP

What is ICCP and how does it prevent marine corrosion?
ICCP (Impressed Current Cathodic Protection) is an active corrosion prevention system that applies a controlled electrical current to the ship’s hull. This creates a protective electrochemical barrier that prevents oxidation and corrosion of the steel structure. Unlike passive systems, ICCP can be adjusted in real-time to maintain optimal protection as conditions change, making it significantly more effective than sacrificial anodes alone.
How much can ICCP systems save in operational costs?
ICCP systems typically deliver ROI within 2-3 years through multiple savings: 50-70% reduction in coating maintenance costs, extended dry-dock intervals (saving $300K-$500K per cycle), reduced fuel consumption from smoother hulls (3-5% efficiency gain), and elimination of frequent anode replacements. Over a vessel’s 25-year lifespan, total savings can exceed $2-3 million.
Are ICCP systems compliant with international maritime regulations?
Yes, our ICCP systems are fully certified by all major classification societies including DNV, ABS, Lloyd’s Register, Bureau Veritas, and ClassNK. They comply with IMO regulations, SOLAS requirements, and environmental standards including EU Biocidal Products Regulation. Our systems are designed to meet or exceed all current and anticipated future regulatory requirements.
How long does ICCP installation take and what's the maintenance schedule?
Initial ICCP installation during dry-dock typically takes 5-7 days for a standard vessel. The system requires minimal maintenance: reference electrodes checked every 2-3 years, anodes inspected annually, and control panel calibration every 12 months. Our remote monitoring capability allows us to diagnose most issues without vessel downtime, ensuring continuous protection with minimal disruption.
