Problems solved by technology

[0003] The left and right compartments of the existing technical scheme are independent compartments, the longitudinal bulkhead components are tightly arranged and have no openings, and the transverse bulkhead is provided with a swash bulkhead, which bears relatively large tank sloshing pressure and is heavy in weight. Furthermore, LNG (liquefied natural gas ) The material used for the liquid cargo tank is 9Ni steel with low temperature resistance, which is expensive and costly

Embodiment Construction

[0032] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the invention is capable of various changes in different embodiments without departing from the scope of the invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0033] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention relates to a double-body liquid cargo tank 10 , the liquid cargo tank 10 includes a tank body 1 and two gas storage chambers 9 formed on the tank body 1 .

[0034] The tank body 1 includes a right tank body 11 and a left tank body 12 which are assembled and welded. Both the right tank body 11 and the left tank body 12 are cylindrical in cross-section larger than a semicircle. The two parts have the same shape, and the cross-section is roughly C-shaped. 11 and the two ends of the length ...

Abstract

The invention provides a two-body liquid cargo tank and a liquid cargo ship. The liquid cargo tank comprises left and right tank bodies welded jointly, the left and right tank bodies are respectively hermetically abutted to form a whole through axial openings, and a storage space is formed inside the left and right tank bodies. A longitudinal bulkhead is connected to the joint of the two tank bodies and partitions the two-body liquid cargo tank into a left cabin and a right cabin, and the longitudinal bulkhead is provided with a plurality of holes through which the left cabin and the right cabin are communicated. A transverse swash bulkhead is not adopted, and a closed structure of the longitudinal bulkhead without holes is modified into a through structure with the holes. Due to lightening holes and drain holes distributed in the longitudinal bulkhead, the left cabin and the right cabin are communicated with each other, and a tank shell structure supporting function as well as a buffering function are realized. In addition, the longitudinal bulkhead is structurally lightened in weight, and high economy is achieved.

Description

technical field [0001] The invention relates to the manufacturing technology of the shipboard container, in particular to a double-body liquid cargo tank and a liquid cargo ship. Background technique [0002] Generally speaking, the left side compartment and the right side compartment of the double-body liquid cargo tank are respectively regarded as two independent compartments, separated by a longitudinal bulkhead in the middle, and a connecting pipe is provided on the longitudinal wall to balance the pressure. There are many girders and stiffeners on the longitudinal bulkhead, the components are arranged densely, the structure is heavy, and the construction cost is high. The left and right cabins are equipped with air chambers, and one liquid cargo tank is equipped with two pump towers. [0003] The left and right compartments of the existing technical scheme are independent compartments, the longitudinal bulkhead components are tightly arranged and have no openings, and ...
