WHAT ARE AND TYPES OF ANODES IN MGPS FOR SHIPS?

The use of anodes, also known as sacrificial anodes, is a crucial part of preventing marine growth on ships.

Anodes are used in cathodic protection systems, which work to protect the metal surfaces of ships from corrosion caused by contact with salt water. When an anode is placed in contact with the metal it is protecting, it corrodes preferentially, effectively «sacrificing» itself in order to protect the metal surface.

Anodes are an essential part of marine growth prevention systems because they help prevent the growth of marine organisms on the ship’s hull. Marine organisms attach themselves to the ship’s hull by taking advantage of the corrosion that occurs when the metal surface is in contact with salt water. The sacrificial anode corrodes instead of the ship’s metal hull, creating a small electrical field that prevents the attachment of marine organisms.

In addition to preventing marine growth, anodes also help extend the life of the ship by protecting it from corrosion. This is important because marine growth can cause a significant increase in drag, which can lead to reduced ship efficiency and increased fuel consumption.

Anodes can come in different types and materials, such as aluminum, zinc, magnesium or mixed metal oxide anodes, each one with different features, useful life and performance. It’s important to work with an expert of MGPS to determine the best anode type for the specific environment, vessel and level of protection required.

In summary, the use of anodes in marine growth prevention systems is essential for protecting ships from corrosion and marine growth, and ensuring the longevity of the ship.

 

There are several types of anodes commonly used in MGPS for boats, these include:

Aluminum anodes: These anodes are relatively lightweight and are commonly used in freshwater environments.

Zinc anodes: Zinc anodes are often used in saltwater environments, as they have a higher potential for cathodic protection than aluminum anodes.

Magnesium anodes: Magnesium anodes are used in saltwater environments, as they have a higher potential for cathodic protection than zinc anodes, however are more reactive and have a shorter lifespan.

Mixed metal oxide (MMO) anodes: These anodes are typically made from a combination of metals, such as iridium and platinum, and offer a longer lifespan and better performance than traditional aluminum, zinc or magnesium anodes.

Hybrid Anodes: some of them are made of mixed metal oxide coated on a substrate of aluminum or zinc, which combine the best features of both MMO and traditional anodes.

The choice of anode type depends on the specific environment, such as the type of water, the pH level, and the salinity. Additionally, factors such as the size and type of boat, as well as the level of protection required, should be taken into consideration when selecting an anode. It’s important to work with an expert of MGPS to determine the best anode type for your boat.

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.
