Impressed Current Cathodic
Protection (ICCP)

Captivating Your Gaze
Recognising the Corrosion Enemy: Picture your metal structure, like a pipeline or a ship, facing an enemy called “corrosion.” This enemy slowly eats away the metal.

The Basic Principle

ICCP works by creating an electrical field around the structure to be protected. This field is generated by an external power source (usually AC mains power converted to DC) that energizes anodes (typically made of graphite, platinum, or other specialized materials). These anodes are installed in the ground or water near the structure.

The Counter-Current

The energized anodes release electrons, which flow through the electrolyte (soil or water) towards the structure (cathode). This creates a counter-current that opposes the natural corrosion current, effectively stopping the corrosion process.

The Protective Potential

The applied current shifts the potential of the structure to a more negative value, making it less susceptible to corrosion. This potential shift is carefully monitored and adjusted to ensure adequate protection without over-protecting the structure, which can lead to other problems.

How the Shield Works:
You become interested in understanding how this high-tech shield, powered by an external source, can protect your metal. It’s like having a force field that pushes corrosion away from your metal.

Seeing the Advantages:
You like the idea that impressed current systems can be strong and reliable, like having a futuristic shield that constantly guards your metal.

Highly Effective

ICCP can provide a high level of protection against corrosion, even in harsh environments like seawater, acidic soils, and high-temperature conditions.

Versatile

ICCP can be applied to various structures of different sizes and shapes. It is suitable for protecting pipelines, storage tanks, offshore platforms, and other metallic assets.

Scalable

The ICCP system can be easily expanded or modified to accommodate changes in the protected structure or environmental conditions.

Remote Monitoring

Modern ICCP systems can be equipped with remote monitoring capabilities, allowing for real-time monitoring and control of the system from a central location.

Large Pipelines

ICCP is frequently used for long-distance pipelines where the high resistance of the soil may reduce the effectiveness of sacrificial anodes. By using an external power source, a controlled and continuous protective current can be applied to the pipeline to counteract corrosion.

Storage Tanks

Above-ground storage tanks that contain corrosive substances, such as chemicals or petroleum, may utilize impressed current cathodic protection to prevent corrosion of the tank walls.

Ship Hulls

In some cases, especially for larger vessels or ships with specific operational requirements, impressed current systems may be employed for cathodic protection. This method provides better control over the protection process compared to sacrificial anodes.

Steel Reinforced Concrete Structures

ICCP can be used to protect the steel reinforcement in concrete structures such as bridges, parking garages, and buildings. This application helps prevent corrosion-induced deterioration of the concrete.

Offshore Platforms

In the offshore oil and gas industry, impressed current cathodic protection is used to protect the submerged steel components of platforms, pipelines, and other structures that are exposed to corrosive seawater.
