IS A CATHODIC PROTECTION THE SAME AS SACRIFICIAL ANODE?

Cathodic protection and sacrificial anode are closely related concepts, but they are not exactly the same thing.

Cathodic protection refers to a method of protecting metal surfaces from corrosion by making them the cathode of an electrochemical cell. This is achieved by connecting the metal surface to a more easily corroded metal (known as the sacrificial anode), which is connected to an electrical circuit. The sacrificial anode corrodes preferentially to the metal surface it is protecting, effectively «sacrificing» itself to protect the metal.

A sacrificial anode, also known as a galvanic anode, is a type of cathodic protection. It is a metallic alloy that is designed to corrode preferentially to the metal it is protecting. When a sacrificial anode is connected to the metal it is protecting and is immersed in an electrolyte, the sacrificial anode corrodes, creating an electrical current that flows between the anode and the metal it is protecting. This creates an electrochemical reaction that effectively «sacrifices» the anode to protect the metal.

Sacrificial anodes are often used in cathodic protection systems for ships and boats, as well as for other underwater metal structures such as pipelines and oil and gas platforms. These systems are also known as marine growth prevention system (MGPS) as it prevents not only corrosion but also marine organisms from attaching themselves to the metal surface.

WHAT IS CATHODIC PROTECTION? PROS & CONS.

Cathodic protection for ships refers to the use of cathodic protection systems to protect the metal surfaces of ships, such as the hull, from corrosion caused by contact with salt water. This is done by attaching a more easily corroded metal (known as the sacrificial anode) to the metal surface that needs protection, and connecting it to an electrical circuit. The sacrificial anode corrodes preferentially to the metal surface it is protecting, effectively «sacrificing» itself to protect the metal.

This process creates a small electrical field that prevents marine organisms from attaching themselves to the metal surface.

 

Pros of cathodic protection for ships include:

  • Cost-effective: Cathodic protection can be a more cost-effective method of protecting ship hulls from corrosion than other methods.
  • Versatile: Cathodic protection can be used on a wide variety of ship hulls, regardless of the material they are made of.
  • Prevent marine growth: Cathodic protection helps prevent the growth of marine organisms on the ship’s hull, which can reduce drag and increase efficiency.
  • Extend the life of ship’s hulls: Cathodic protection can extend the life of ship’s hulls by preventing corrosion.

 

Cons of cathodic protection for ships include:

  • Maintenance: Cathodic protection systems require regular maintenance, such as checking and replacing the anodes.
  • Limited protection: Cathodic protection may not be effective in all environments, such as when there are high levels of electrical interference or when the ship’s hull is in contact with non-conductive materials.
  • Limited protection against mechanical damage: Cathodic protection doesn’t provide protection against mechanical damage, it only protects the ship’s hull from corrosion
  • Limited protection in areas with high salinity or other extreme conditions: Cathodic protection may not be effective in areas with high salinity or other extreme conditions, and the anodes may need to be replaced more frequently.

 

It’s important to work with experts in cathodic protection to design and install the appropriate system for your specific needs, as well as monitor and maintain it to ensure its proper performance.
