The corrosion of the ship´s structures and equipment is a considerable proportion of the total corrosion losses, thus it is the basis for further investigation and developments for protection from corrosion, providing the ship building companies with corrosion preventive materials and tools. This paper deals with assessment of aggressiveness of the corrosive environment and operating conditions, corrosion resistance of ship structures and typical forms of ship´s structure corrosion. Methods of corrosion prevention of ship structures analysis are detailed depending on ship type and environment around the structure. Some of ship structure operation – technical, ecological corrosion prevention features are given. The research on corrosion of ship structure is based by needs to enhance research about use of nanostructured multifunctional materials and nanotechnologies on seagoing ships.
