Independent Liquefied Gas Carrier

Abstract

Independent liquefied gas carrier belongs to the field of liquid cargo hull structure, including hull, hydraulic pump, cantilever beam, storage tank, compartment, connecting rod, release door, release ejector rod, release pin, hydraulic pump station, hydraulic ejector rod, release Buckle and push rod, the storage tank on the main deck of the hull is separately installed on the left and right sides of the cantilever beam and separated by a compartment, the storage tank is bound to the cantilever beam by tripping, and the input end of the hydraulic ejector rod is a hydraulic pump , the left and right chords of the storage tank are provided with independent release doors, the release doors are fixed on the hull through release pins, and each release door is provided with two connecting rods to connect the release pins together, and the upper and lower ends of the connecting rods are fixed with release tops The input end of the release ejector rod is a hydraulic pump station, and the other output end of the hydraulic pump station is a telescopic push rod fixed on the cantilever beam. The liquefied gas ship solves the problem that the liquefied gas currently in shipping can only escape by abandoning the ship when it encounters an emergency and the on-board fire protection system cannot solve it, causing huge losses and excessively polluted sea areas.

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...

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.
