Description

Technical Field

[0001] The present application belongs to the technical field of shipbuilding, and in particular relates to an integrated deck tank and a ship. Background Art

[0002] Dual-fuel liquefied gas ships use dual fuels as power, and generally have a deck tank for gas on each side of the open-air main deck of the cargo hold. In the process of installing the entire deck tank of a traditional dual-fuel liquefied gas ship, the deck tank structure is generally assembled at the platform stage to obtain a deck tank with basic functions; at the dock stage, the formed deck tank with basic functions is separately hoisted to the fixed base on the left and right decks, and then the frame-type outfitting and maintenance platform structure is covered on the liquid tank, and the platform support legs are directly welded to the hull deck, and then the gas valve group, pipe bracket, pipe, electrical equipment bracket, electrical equipment, inclined ladder steps and other supporting components are installed on the outfitting and maintenance platform.

[0029] In the relevant technology, LPG carrier is a ship specially used for transporting low-temperature and volatile liquefied petroleum gas (LPG). As a new type of high-value-added ship, the market demand is strong. Deck tanks are a kind of pressure container for ship handling. They can be used to load liquefied goods, and can also be used for the ship's gas supply system and cargo exchange requirements. They are commonly installed on LPG carriers. my country has abundant water resources and frequent maritime transportation. The demand for ships is huge, and the demand for storage devices such as ship tanks and containers is also increasing. The storage device must meet the conditions of good strength, ductility, and corrosion resistance. Usually, a deck tank for gas is arranged on each of the left and right sides of the open-air main deck of the cargo hold. In the past, in the process of installing the entire deck tank on a dual-fuel liquefied gas ship, the deck tank with basic functions assembled with the deck tank structure is usually assembled at the platform stage first. At the dock stage, the deck tank with basic functions formed first is separately hoisted to the fixed bases on the left and right decks. Then, the frame-type outfitting and maintenance platform 301 structure is covered on the liquid tank, and the platform support legs are directly welded to the hull deck. Then, the gas valve group 304, pipe brackets, pipes, electrical equipment 206 brackets, electrical equipment 206, inclined ladder 303 steps and other supporting components are installed on the outfitting and maintenance platform 301. This construction method has great defects. First, due to the inclined structure of the hull structure (generally, the deck surface will have an inclined surface, especially the raised deck structure), precision errors will occur after assembly. The support feet of the entire outfitting and maintenance platform 301 need to be lifted by a crane in mid-air for on-site trimming and cutting of the support feet. During the docking stage, the platform support feet are directly welded to the deck surface. If the support feet are trimmed and cut multiple times, it will affect the performance of the deck structure (the deck structure is a secondary shielding area, a first-level open fire, and a high risk factor). Secondly, since the outfitting platform is a frame structure, the support feet and the frame not only occupy a large deck space, but are also very heavy, which has a certain impact on the speed required by the shipowner. Finally, the most important thing is that the entire construction process is carried out in the docking stage, which has a great impact on the docking period.

[0030] In view of the above problems, the embodiments of the present application provide an integrated deck tank and a ship, which can reduce the impact on the deck caused by multiple trimming and cutting of supporting feet when the tank body 1 is installed on the ship, and can shorten the dock construction period and improve construction efficiency.

[0044] The integrated deck tank of this application can be assembled by the following methods:

[0045] First, according to the installation drawings, the basic tank body 1 is constructed by means of steel plate compression and other operations. The front and back of the bottom of the tank body 1 are positioned and marked according to the drawings, and the tank body support 4 is installed. The middle position of the upper part of the tank body 1 is positioned and marked according to the drawings, and the inspection door 302 and the lifting lug 5 are installed. The front and back positions on both sides of the upper part of the tank body 1 are positioned and marked in turn according to the drawings, and multiple first supporting legs 202 are installed. Tools such as measuring levels can be used to find the level. Spot welding can be performed first, and the bottoms of the first supporting legs 202 can be gradually cut in sequence so that the upper planes of all distributed first supporting legs 202 remain horizontal. Pipeline support angle steels 203 are welded, and the platform steps are aligned.

[0047] Most of the assembly work is done at the platform stage. All the parts that come with the tank 1 and are installed later are constructed at the platform stage. The tank 1 is hoisted as a whole after it reaches a fully integrated state. In the dock stage, other work can be done only after hoisting. After this assembly method is implemented, compared with the existing technology, it not only reduces the weight of the whole ship, but also prevents the support feet from being trimmed and cut on site many times at the dock stage, which affects the deck of the secondary shielding area. It can also shorten the dock construction period and improve construction efficiency.
