LNG CARRIER OR LPG CARRIER Russian patent published in 2018 - IPC B63B25/16 B63B11/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and is aimed at obtaining an economical hull structure, using an independent prismatic tank of large volume with respect to a ship size and reducing material costs. Provided is a LNG ship or a LPG ship having a structure in which a substantially prismatic tank is installed inside a hold while not being integrated with a hull structure material, wherein the tank is a long tank 30, which has a larger dimension of a ship longitudinal direction than that of a ship width direction and is installed inside the hold along a ship longitudinal direction, and the long tank 30 is divided into two or more liquid cargo compartments 30-1, 30-2, 30-3 in the ship longitudinal direction by one or more bulkhead plates, each of which is formed in the ship width direction as one plate. Upper part of the central compartment for liquid cargo is designed as the center of thermal deformation of the tank in the forward-backward direction. In the material of the structure of the body there are anchorage places for stopping for thermal deformation, to be in front and rear in the direction of the center line of the vessel in accordance with the retaining part.

EFFECT: increase in the volumetric efficiency of the vessel and hull of the vessel is achieved, minimization of stresses from thermal deformation.
