A new method of cleaning ships' hulls and repairing equipment without the ships having to come back to port has been tried out experimentally in the Soviet Union. The idea has special relevance to fishing vessels which often have to leave rich fishing grounds to put in at foreign ports for repairs. Members of the clean and repair team have light conventional diving equipment with special cleaning equipment. They work an eight hour day and on the last expedition cleaned the hulls of ten medium freezer trawlers which had been at sea from four to seventeen months, increasing their fishing time by 80 per cent. Research has shown that most often ships are fouled by crustaceans which cover the hull in two or three layers, each 30 to 60 mm thick. This has the effect of reducing the ship's speed, increasing fuel consumption and increasing the risk of the engines overheating. Research is still continuing.
