Independent liquefied gas ship

Abstract

The invention discloses an independent liquefied gas ship, and belongs to the field of liquid cargo ships. The liquefied gas ship comprises a ship, hydraulic pumps, a cantilever beam, storage tanks, separation cabins, connecting rods, release doors, release ejector rods, release pins, hydraulic pump stations, hydraulic ejector rods, trippers and push rods. The storage tanks on a main deck of the ship are separately arranged on the left side and the right side of the cantilever beam, are separated from one another by the separation cabins and are bound on the cantilever beam by the aid of the trippers, the hydraulic pumps are arranged at input ends of the hydraulic ejector rods, the corresponding independent release doors are arranged on a left chord and a right chord of each storage tank and are fixed onto the ship by the aid of the corresponding release pins, the corresponding release pins in each release door are connected with one another by the two corresponding connecting rods, the corresponding release ejector rods are fixed to the upper end and the lower end of each connecting rod, the hydraulic pump stations are arranged at input ends of the release ejector rods, and each telescopic push rod is arranged at an output end of the corresponding hydraulic pump station and is fixed onto the cantilever beam. The liquefied gas ship has the advantage that problems of tremendous loss and excessively large polluted sea areas due to a ship abandonment escape mode adopted when a firefighting system on an existing ship cannot handle sudden events related to shipped liquefied gas can be solved.

Description

technical field [0001] The invention relates to an independent liquefied gas carrier and belongs to the field of liquid cargo hull structure. Background technique [0002] A liquefied gas ship is a liquid cargo ship specially used to transport liquefied natural gas or oil. According to the liquefaction method, oil and natural gas can be divided into three types: pressure type, semi-refrigerated semi-pressure type and refrigerated type. Then several pressure storage tanks are installed on the hull. According to the installation method of the hull structure, the tank can be divided into two types: independent type and membrane type. The membrane structure ship adopts a single-hull structure, and the inner shell of the hull is the load-bearing shell of the liquid cargo. The independent structural ship adopts a double-hull structure, and the cylindrical, cylindrical, spherical and other storage tanks are placed in the cabin. Its components can be divided into two parts: hull com...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is that when the liquefied gas ship in the current shipping encounters an emergency and the on-board fire protection system cannot be solved, it can only escape by abandoning the ship, resulting in huge losses and excessive pollution of the sea area.
