When marine growth adhere to the surface of ship's hull, fuel consumption increases, and conventionally antifouling paints consisting of organic tin compounds have been used to prevent adhering. However, organic tin compounds dissolving from these are known to contaminate the environment, and tributyl tin compounds were designated as toxic substances in September 1990. A substitute antifouling system is required. MHI has been studying the antifouling method as one of the most important technologies in shipbuilding for many years, and as an achievement of the past four years, the authors have reached the first step of practical development of technology for preventing adhesion of marine growth electrolytically by coating the underwater portions of the ship's hull surface with an electro-conductive paint film.
