Zinc Anode Calculation for Ships: A Guide to Effective Corrosion Prevention


Corrosion is a major problem for ships, and it can lead to costly repairs and maintenance. Zinc anodes are an effective way to prevent corrosion on ships, but it’s important to calculate the right number of anodes needed to protect the ship. In this blog post, we’ll discuss zinc anode calculation for ships, how to determine the right number of anodes, and how they can help prevent corrosion.

Section 1: What are Zinc Anodes?

Zinc anodes are sacrificial anodes made of zinc that are attached to a ship’s hull. They work by corroding instead of the hull, providing protection against corrosion. Zinc anodes are a critical component of a cathodic protection system, which is used to protect the ship’s metal structure from corrosion.

Section 2: Why is Zinc Anode Calculation Important?

Zinc anode calculation is important because it determines the number and size of anodes needed to effectively protect the ship’s hull from corrosion. Without proper zinc anode calculation, the ship may not be fully protected, and corrosion can still occur.

Section 3: How to Calculate Zinc Anodes for Ships

To calculate the number of zinc anodes needed for a ship, you’ll need to know the ship’s wetted surface area (WSA), which is the surface area of the hull that is in contact with the water. The WSA is usually measured in square meters.

Once you know the WSA, you can use our design services to determine the number and size of anodes needed for the ship. Our designs follow all the international standards & considers the size and shape of the ship, as well as the type of water it will be sailing in.

Section 4: Benefits of Zinc Anodes for Ships

Zinc anodes provide several benefits for corrosion prevention on ships, including:

  • Cost-effective corrosion prevention: Zinc anodes are a cost-effective way to prevent corrosion on ships, as they corrode instead of the hull.
  • Easy to install: Zinc anodes are easy to install and require minimal maintenance.
  • Customizable: Zinc anodes can be designed and customized to meet the specific requirements of different types of ships.
  • Long-lasting protection: Zinc anodes can provide long-lasting protection against corrosion, as they corrode slowly over time.

Section 5: Conclusion

Zinc anode calculation & design is an important aspect of effective corrosion prevention on ships. By calculating the right number and size of anodes needed for the ship, you can ensure that it is fully protected against corrosion.
