Why It’s Crucial to Have Sacrificial Anodes

Ship maintenance is a serious matter. Maritime workers, as well as passengers, put their lives at risk when boarding a vessel. It is a common knowledge that maintenance and control of sea vessels happen on its inside. In fact, there exists another equally important part of marine engineering which is Cathodic Protection. Basically, it is a way to control corrosion on parts of sea vessels that are submerged or are underwater.

Cathodic Protection is an investment worth having as it could help in saving hundreds of billions every year for industrialized countries. There are various forms of Cathodic Protection and one of them is sacrificial anodes on ships. Cathodic Marine provides exactly this.

What are Sacrificial Anodes?

True to its name, sacrificial anodes are to be sacrificed for the protection of other more important metal parts of the ship. These metal parts are especially more reactive, as they are a highly active kind of metal, compared to the original parts of the ship making them corrode first and the ship protected.

There are various parts in which sacrificial anodes are used in ships. It is mainly used in subsea

Structures being these are more prominent with corrosion. However, they are also very useful and are used for pipelines, monopiles, quay and harbor walls, storage tanks, etc. Even if a part is only partially submerged, it is encouraged that sacrificial anodes be deployed on it as well.

What are Sacrificial Anodes made of?

Sacrificial anodes come in different types depending on the material used and uses. There exist kinds made of zinc, aluminum, magnesium or a mixture of two. They depend whether the anodes are used for ship hulls, platforms, pipelines, etc. Magnesium, on the other hand, is specifically used for fresh water requirements.

Every kind of sacrificial anode by Cathodic Marine has performance standards to be met as well as set specifications. Zinc anodes, for instance, is made with high purity zinc alloy. Aluminum anodes, in fact, a mixture of aluminum, indium, and a few other metal additions for maximum efficiency in sea water.

What are the benefits of having Sacrificial Anodes?

As mentioned, sacrificial anodes is an investment worth having as its effects can last up to 25 years. That would mean adding 25 more years to your ships’ parts that would have been corroded by now without it. Considering its long life cycle, the cost would be lower overall. And since it is a method of maintenance and control in itself, there is also no need for further maintenance.

Its deployment is also an ease since you are not required to make any modifications or alter any part of your ship. Sacrificial anodes are deployed usually through the use of lead wires or cast-in straps. The ship’s hull would then be linked by these metals electrically.

Cathodic Marine guarantees the accurate deployment of the sacrificial anodes as well as the right selection of the kind of anode appropriate for your ship.
