SHIP HULL Russian patent published in 1996 - IPC

FIELD: shipbuilding. SUBSTANCE: ship hull has combination (longitudinal for deck with bottom and transverse for sides) strengthening plates of skin, longitudinal and transverse web and intermediate beams. Sheer strake and bilge strake are strengthened with longitudinal members of variable direction; side lengths of deep frames have varying width. Longitudinal members of variable direction of sheer strake and bilge are similarly directed within one deep frame spacing; they are rigidly connected with beams and floors and are made of strips of all latticework notched-drawn plates forming welded I-section. Desk stringers are strengthened with strips of all-latticework notched-drawn plates at areas where they are connected with sheer strake; holes in all-latticework notched-drawn plates are filled with fine concrete. EFFECT: higher strength of hull at reduced metal usage. 6 cl, 5 dwg
