Abstract
PURPOSE:To improve the pollution preventive performance of the shell of the hull while increasing the strength of the hull by forming the shell of the hull in double structure with an inner shell plate and an outer shell plate and shaping the outer shell plate with a large number of small through-holes by metal having pollution preventive property. CONSTITUTION:Bending preventive materials 3 in steel with girder structure are mounted outside the inner shell plate 2 consisting of a steel plate, the outer shell plate 1 is installed outside the bending preventive materials 3, and the shell of the hull is formed by these plates and materials. The outer shell plate 1 is made up by a metallic material having excellent pollution preventive performance such as clad steel obtained by cladding copper or a copper alloy 1a to steel 1b, and has a large number of the small through-holes 4. Since the through-holes 4 function for equalizing hydraulic pressure in space between the outer shell plate 1 and the inner shell plate 2 to hydraulic pressure at the outside of the outer shell plate 1, the strength of the outer shell plate 1 and the bending preventive materials 3 can be decreased.
