Corrosion poses one of the biggest problems that marine engineering need to solve. The problem stems from the exposure of metals that come in contact with the salt in the water. It weakens the exposed parts of boats. Although some metals corrode slower than others, repairs are imminent and costly. This is where a cathodic protection system becomes useful.

Also called a CAPAC, it provides a cathodic protection system on active mode. It provides a means of protection for all types of materials that may suffer from corrosion caused by regular contact with the salt content of sea water.  Most seafaring boats and vehicles depend on it for better protection. It is a kind of protection that involves a simple procedure that separates active from passive cathodic protection.


Active Cathodic Protection

Active Cathodic Protection System is run with direct current.  The current can adjust itself to anything that is massive in size. It is this feature that separates Active from Passive Cathodic Protection. The direct current is forcefully run through the whole hull of a boat or ship protecting all metals that it comes into contact with.  The current provides the whole hull with equal amounts of electricity that prevents corrosion from happening.

On larger ships, the current must be on a uniform level so that it can withstand constant changes in the water.  Everything must be considered and regulated because even a slight change in water temperature may affect the protection system. However if the running current is regulated, the hull can withstand any change in the water. A CAPAC system ably does this with its cathodic protection measures.


These are measures that help regulate the protection system and eliminate the chances of corrosion settling in. It is one of the ways in which CAPAC helps protect the marine environment. It is worth noting that marine corrosion has a big effect on marine industries.
