Liquefied gas carrier
A technology of liquefied gas ships and liquid tanks, which is applied in the direction of hull, ship construction, and partial cabins in the hull, etc. It can solve problems such as the inability to meet the demand for tank capacity, and achieve the goal of reducing the center of gravity of the entire ship, improving the stability of tank damage, and reducing divisions.

Embodiment 1
[0050] Such as figure 2 As shown, Embodiment 1 provides a cargo hold structure, the vertical section 301 and the horizontal section 303 of the cargo hold structure are connected through a bent section 302, and the bent section 302 is arranged at the junction of the side plate 11 and the bottom plate 12, Its inner side has a slope of 45°, and the overall section is roughly triangular. Such setting can make the overall center of gravity of the ship and the center of gravity of the ballast water tank deviate from the baseline, thereby improving stability.
[0051] The top corner of the liquid tank 2 is a right angle. In order to avoid the stress concentration of the right angle welding, the rounding treatment can be performed on the right angle or between adjacent surfaces, and a circular arc transition is adopted at the butt joint of the outer plate; the bottom of the liquid tank 2 is equipped with a curved The turning portion 201 matched with the folding section 302 also has ...
Embodiment 2
[0060] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the vertical section 301 and the horizontal section 303 of the protective cabin 3 are directly connected, and the connection between the two is located at the junction of the side plate 11 and the bottom plate 12, and the protective cabin 3 is L-shaped. . Therefore, the liquid tank 2 can be correspondingly configured as a cuboid structure with a quadrangular cross-section, and the top and bottom corners are right angles, so as to meet the larger tank capacity requirement.
[0061] The liquid tank 2 of this embodiment is only suitable for ships with a very large square coefficient, such as ships with a square coefficient above 0.8. Although the liquid tank 2 is set as a quadrangle to increase the cabin capacity, but due to the lack of the bending section 302, the overall line shape of the cargo hold structure is not thin enough, forming a line shape limit point, and the hull below...
Embodiment 3
[0063] Such as Figure 4 As shown, the difference between the present embodiment and the first embodiment is that the liquid tank 2 is a diamond-shaped cabin, and its section is octagonal. In order to prevent interference, the top of the vertical connecting section 301 is set as a triangle, that is, the existing topside tank is connected with the bent section 302 and the horizontal section 303 through the vertical connecting section 301, and the center of gravity of the cargo tank structure is lowered. In order to increase the tank capacity, the section of the diamond tank can be a regular octagon or a non-regular octagon, and the smaller the inclination angle of the top and bottom turning parts, the larger the tank capacity.
[0064] Such as Figure 6 As shown, three liquid tanks 2 are arranged inside the cargo hold structure of the present invention, that is, a first liquid tank 21 , a second liquid tank 22 and a third liquid tank 23 arranged in sequence from front to back....
