In India the cost of corrosion prevention in marine industries may be of the order of Rs.100 crores. The different areas of service are: (1) Immersed in seawater (2)'Splash waterline (3) Super structure area near seawater. Painting is the principal means of protection; other methods such as cathodic protection, are used only in conjunction with paint coatings. Hence it is necessary to provide long term maintenance-free protection and to minimise the time out of service when maintenance of ship is essentially required. In this article the mechanism of corrosion prevention by paints, pretreatment, paint system, method of application of paint for &fferent types of structures and equipments used in marine environments are described. A comprehensive protective system consisting of primer + under coat + finishing paint + antifouling paints is included. Application of the organic coatings and details of type of fouling and the use of different types of antifouling compounds used in the paint formulation are given. The protective schemes for dock and harbour installation, offshore structure, super structures and deck areas are discussed. The causes of paint failure and the specification, requirements of paints are described.
