Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments 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.

[0026] like figure 1 and figure 2 As shown, the present invention is a combined dome structure used for liquefied natural gas fuel tanks on LNG powered ships, replacing the original separate liquid dome and gas dome structures. A liquefied natural gas fuel tank 2 is provided on the LNG powered ship 1, and a combined dome structure as a combined dome 3 is arranged on the said liquefied natural gas fuel tank 2. in the middle of the rear. The joint dome 2 is...

Abstract

The invention relates to a combined dome structure for a liquefied natural gas fuel cabin on an LNG power ship, which is arranged at the middle position of the rear part of the cabin top of the liquefied natural gas fuel cabin along the length direction of the ship, and comprises a base (15) and a cover plate (14), the bottom of the base (15) is fixed to the top of the liquefied natural gas fuel cabin, the top of the base (15) is provided with the cover plate (14), the cover plate (14) comprises a body (16), a channel for liquefied natural gas to enter and exit from the fuel cabin and a channel for gaseous natural gas to be discharged out of the fuel cabin are integrated on the body (16) of the cover plate (14), and the body (16) of the cover plate (14) is provided with an opening. And a personnel access channel and a material access channel are also integrated on the body (16). The combined dome structure is simple in composition and high in integration, and the problem that a separated dome is difficult to arrange is effectively solved.

Description

technical field [0001] The invention relates to the technical field of liquefied natural gas storage and transportation equipment, in particular to a combined dome structure of an LNG-powered ship and an LNG-powered ship containing the structure. Background technique [0002] As a green, clean and high calorific value energy, the demand for liquefied natural gas in my country shows a rapid growth trend, and the gap between supply and demand is expanding rapidly. Therefore, by introducing natural gas resources from overseas, adjusting the energy structure, making up for energy shortages, and meeting the demand for emerging energy from the increasingly accelerated national economic development has become an important decision for my country to implement its energy strategy. At present, ships using LNG as fuel continue to come out, and the technology is gradually maturing. With the promotion of LNG as a marine fuel, LNG-fueled ships have attracted more and more attention from ...
