The external hull of the ship is usually protected by means of paint coatings. The protective paint coating, however, is easily damaged in localized areas by mechanical action such as anchors chain and by erosion of parts of the stern frame and the leading edge of the rudder. Corrosion also occurs at rivet heads and welds. Cathodic protection can be of value in preventing or greatly reducing corrosion at these areas. Impressed current cathodic protection systems are widely used to protect the external hulls of large tankers/vessels and bulk carriers which could not be satisfied adequately by sacrificial anode systems. Often Impressed Current Cathodic Protection or ICCP systems are preferred, as they can be easily controlled in the control room.

Seawater is used to cool machinery and plant on board all types of marine vessels. It is also used in petro-chemical plants, power stations and other land-based industries, where there is access to the ocean. Although this benefits supplying a free cooling agent, it also causes corrosion and blockage to the cooling water pipeline system.
