Problems solved by technology

[0002] At present, there are two types of layouts for the existing ship LNG gas storage tanks: one is the open layout above the main deck of the ship, which can make reasonable use of the hull space and solve the safety problems caused by gas leakage, but will cause the hull The center of gravity moves up, which affects the stability of the ship; second, it is completely placed inside the closed cabin, which solves the stability problem of the ship. If gas leakage occurs, the closed space will bring great safety hazards. It can be seen that the current There are obvious deficiencies in the placement layout of some ships' gas storage tanks. Based on this, a reasonable layout of the gas storage tank placement device is now provided.

Abstract

The invention provides a gas storage tank bearing device for an LNG (liquefied natural gas) single-fuel ship, which structurally comprises a hull. The hull is separated into an open-air part and a cabin part by a deck, wherein the cabin part comprises an afterpeak, a water ballast space and an engine room in sequence from the stern; a gas storage tank cabin connected with the deck is arranged between the water ballast space and the deck; the gas storage tank cabin is connected into a cuboid box shape through a supporting plate; a gas storage tank is arranged on the bottom of the gas storage tank cabin. Compared with the prior art, the gas storage tank bearing device for the LNG single-fuel ship has the advantages that the whole space structure layout is compact, the additionally arranged gas storage tank does not occupy too much space, the practicability is high, the application scope is wide, and promotion is easy.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a device for placing an air storage tank for an LNG single-fuel ship with a simple structure and ensuring the stability of the ship. Background technique [0002] At present, there are two types of layouts for the existing ship LNG gas storage tanks: one is the open layout above the main deck of the ship, which can make reasonable use of the hull space and solve the safety problems caused by gas leakage, but will cause the hull The center of gravity moves up, which affects the stability of the ship; second, it is completely placed inside the closed cabin, which solves the stability problem of the ship. If gas leakage occurs, the closed space will bring great safety hazards. It can be seen that the current There are obvious deficiencies in the placement layout of some ships' gas storage tanks. Based on this, a device for placing gas storage tanks with a reasonable layout is now prov...
