Rhombus-shaped isolated void compartment structure of liquefied gas ship

Abstract

The invention belongs to an isolation void structure of a liquefied gas ship in the field of ship layout in the field of shipbuilding. The technical proposal is: the isolation void is arranged between two liquid cargo tanks, respectively located on both sides of the transverse bulkhead and outside the isolation void It is connected with the outer plate of the hull, so that the outer plate of the hull forms the outer wall of the isolation void; the upper part of the isolation void is connected with the main deck, so that the top of the main deck forms the isolation void, and the lower part of the isolation void is connected with the inner bottom, so that the inner bottom forms an isolation void. The bottom of the cabin; the inner wall of the cofferdam is enclosed by two transverse walls, two oblique walls and one longitudinal wall. One side of the wall is butted with the outer plating of the hull, and the longitudinal bulkhead is butted with the transverse bulkhead; there is a gap between the inner wall and the cargo tank. Adopting this technology can reduce the angle of inclination when the ship is damaged, and improve the safety of the ship. While improving the damage stability of the ship, it not only reduces the steel consumption but also improves the energy efficiency level of the ship.

Description

technical field [0001] The invention relates to the field of ship layout in the field of ship manufacturing, in particular to an isolation void structure for a liquefied gas ship. Background technique [0002] At present, the world's gas energy consumption and demand for gas chemical raw materials continue to rise, which brings great opportunities for the development of liquefied gas carriers (referred to as liquefied gas carriers). Under this international situation, all ship design units have increased their efforts in the research and development of liquefied gas carriers. [0003] In the process of designing and producing liquefied gas carriers, the damage stability and safety of the cargo hold area is the top priority. In order to improve the damage stability of ships, the double-hull design scheme of the ballast tank in the cargo hold area is often adopted, and the double-hull width in the usual double-hull arrangement of the ballast tank needs to be greater than one-...

AI Technical Summary

Problems solved by technology

[0004] In order to address the above technical problems, the present invention provides a diamond-shaped isolation void structure for a liquefied gas ship, which is more efficient and safer, and solves the problem of low utilization rate of the existing double-hull design.
