Inner plating of side is structurally combined with respective longitudinal bulkheads of some cargo tanks. Longitudinal bulkheads are flat in construction and are provided with vertical pillars on section extending from inner bottom as far as upper inter-side platform and with longitudinal stiffeners on section from upper inter-side platform as far as upper deck; framing members are located inside inter-side space. Tanks are divided in pairs by center corrugated longitudinal bulkhead; corrugated bulkheads are provided with horizontal corrugations and with at least one pillar located on deep frame in each tank. ^ EFFECT: enhanced damage resistance and durability of tanker. ^ 17 cl, 6 dwg |
