MARINE CORROSION CONTROL
The gradual destruction of material by a chemical reaction with it environment is known as corrosion. It has been estimated that the total cost of marine corrosion worldwide anywhere is between $50-80 billion every year. The marine industry endures a harsh environment where corrosion is severe and if not controlled can severely impact individual and companies.
There are two basic type of corrosion in marine industry you should be aware of for potential damage.
• Electrolytic corrosion also known as electrolysis is stray current induced that develop from a power source: this type of corrosion can damage bearings, washers, oil and water coolers or even your engine.
• Galvanic corrosion occurs from the contact of two dissimilar metals in the same electrolyte. Galvanic corrosion require three conditions to thrive: the two metals must be widely separated on the galvanic series, they must be in electrical contact and their surfaces must be bridged by electrically conducting fluid.

However corrosion doesn’t affect your vessels alone, it also affect the lives of the sea creatures. The corroded metal particle that fall into the water body endangered the lives of the sea creatures living in it. Corrosion thereby destroys the metal and also affects the surrounding.
To opt out of corrosion, prevention is rather better than cure. Below are some measures of preventing or controlling corrosion:
• Hydro blasting
• Sand basting
• Painting and coating
These are the only ways in which corrosion can be controlled.
