FIELD: shipbuilding; building ships for operation in open sea, sea oilfields in particular. ^ SUBSTANCE: proposed ship has several trunks running through hull. Zones of deck plating and/or bottom plating located between trunks are shifted relative to remaining portion of deck plating and/or bottom plating, closer to transversal neutral axis of hull. Zone between zones forms gradual change from one level to another. Zone between remaining portion of deck plating and bottom plating and shifted zones forms stepped change with one or more steps. Ship may have shifted zones of deck plating and/or bottom plating on aft side of trunk nearest to ship's stern and on fore side of trunk nearest to bow in longitudinal direction. ^ EFFECT: reduced concentration of stresses at action of working loads on ships. ^ 4 cl, 10 dwg |
