Problems solved by technology

[0004] It is the first time in China that a new type of dual-fuel container ship adopts a brand-new LNG tank structure design. There is no experience in the construction of such a new type of container ship LNG tank structure at home and abroad. There are double empty cabins on both sides of the cabin, and fuel tanks are arranged between the double empty cabins, which greatly increases the width of the bilge area. The existing division will affect the independence of the LNG tank. big impact

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific examples shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0041] The present invention belongs to a kind of total section carrying method of LNG tank of novel container ship, such as Figure 9 As shown, the LNG tank is in the shape of a cuboid as a whole, the LNG tank is octagonal, the bottom of the LNG tank is the pipe area, the sides of the LNG tank are empty, and the middle of the empty tank is the fuel tank.

[0042] Such as Figure 8 Shown, a kind of total section loading method of novel container ship LNG cabin,...

Abstract

The invention relates to a block carrying method for an LNG (Liquefied Natural Gas) cabin of a container ship, which comprises the following steps of: dividing an LNG cabin into 10 blocks by sections, and respectively assembling the blocks to obtain a bottom block, a left bilge block, a right bilge block, a left side block and a right side block, a left inner shell block and a right inner shell block, a deck block, a front bulkhead block and a rear bulkhead block; then using the bottom block as a reference section, combining the left bilge block and the right bilge block with the bottom block, then rotating the front bulkhead block and the rear bulkhead block and then normally hoisting the parts on the bottom block, after folding and fixing, sequentially hoisting the left inner shell block, the right inner shell block, the port side block and the starboard side block, and finally hoisting the deck block; and completing the loading of the whole cabin block of the LNG cabin. According to the method disclosed by the invention, the sectional total assembly carrying efficiency is improved, the outfitting integrity of the void cabin is facilitated, the carrying folding welding workload is reduced, the influence of subsequent carrying construction on the internal construction of the LNG cabin is reduced, and the construction period of the LNG cabin is shortened.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for carrying a general section of an LNG tank of a container ship, a general section of the LNG tank and a container ship. Background technique [0002] As a clean energy source, LNG has obvious advantages in energy saving and emission reduction, especially in the emission of sulfide and nitride. Having received more and more attention from the shipping industry, container ships use LNG tanks to transport LNG. [0003] Patent No. CN209479895U discloses a B-type LNG fuel tank anti-sway device and a B-type LNG ship. This invention enables the lateral load of the independent liquid cargo tank to be effectively transmitted to the hull, and the load is transmitted through laminated wood to avoid heat transfer. The effective heat insulation of the cryogenic LNG tank is guaranteed. [0004] It is the first time in China that a new type of dual-fuel container ship adopts ...
