In the harsh marine environment, one of the biggest threats to a ship's structural integrity is corrosion, particularly on the hull and submerged metal components. Impressed Current Cathodic Protection (ICCP) systems are one of the most effective methods of preventing this type of damage. These systems offer a long-term, automated, and efficient solution to hull corrosion, ensuring the safety, durability, and efficiency of maritime vessels.
At Serden Ship Supply Marine Electric & Electronics Ltd., we specialize in the installation, retrofitting, and maintenance of ICCP systems for all vessel types. Our turnkey solutions include engineering, electrical installation, control system integration, commissioning, and after-sales support—helping our clients achieve maximum corrosion protection with minimal operational effort.
ICCP (Impressed Current Cathodic Protection) is an advanced corrosion prevention system that uses a controlled electrical current to prevent galvanic corrosion on submerged parts of a ship—especially the hull, propeller shaft, rudder, and sea chests.
Unlike traditional sacrificial anodes, ICCP systems use:
Reference electrodes to measure hull potential
Power control units to regulate current
Inert anodes (e.g., mixed metal oxide) to deliver protective current
A closed-loop control system that adjusts current based on seawater conductivity and vessel conditions
Onboard corrosion analysis and hull inspection
Existing protection system review (if any)
Selection of appropriate ICCP system based on hull size, material, and voyage patterns
Preparation of engineering drawings and class approval documentation
Anode and reference cell layout planning
Hull preparation for anode and electrode mounting
Installation of anode cofferdams and seal welds
Reference cell insertion and placement
Shaft grounding brush system setup
Mounting of junction boxes and cabling trays
Power control cabinet installation
Connection of anodes, sensors, and control electronics
Wiring of reference electrodes to the control panel
Integration with the ship's automation or monitoring system
Safety interlocks and alarm configuration
Automatic adjustment of impressed current based on seawater conditions
Real-time hull potential monitoring
Data logging and trend analysis
Alarm system for over- or under-protection
