Embodiment Construction
[0022] Below we will further elaborate on the transverse bulkhead structure used on the large LNG ship of the present invention in conjunction with the accompanying drawings and specific embodiments, in order to understand its structural composition and working method more clearly, but this cannot be limited by this protection scope of the invention.
[0023] The invention is used as a transverse bulkhead structure on a large LNG ship. The large-scale LNG ship is equipped with a liquefied natural gas containment system. The containment system is provided with a plurality of liquid cargo tanks C, and a vertically arranged transverse compartment A is arranged between the bow area and the liquid cargo tanks C. In the midship area A horizontally arranged transverse compartment B is provided between adjacent cargo tanks C, and a vertically arranged transverse compartment A is provided between the stern area and the cargo tank C. Such as figure 1 As shown, the containment system o...

The invention relates to a transverse bulkhead structure used on a large LNG (liquefied natural gas) ship, a liquefied natural gas containment system is arranged on the large LNG ship, a plurality of liquid cargo tanks are arranged in the containment system, transverse bulkheads are vertically arranged between a ship bow area and the liquid cargo tanks, and transverse bulkheads are horizontally arranged between adjacent liquid cargo tanks in a ship middle area. A vertically-arranged transverse bulkhead is arranged between the stern area and the liquid cargo tank, the transverse bulkhead structure comprises a vertically-arranged transverse bulkhead and a horizontally-arranged transverse bulkhead, the arrangement direction of a main beam of the vertically-arranged transverse bulkhead is vertical, so that a vertical channel and a ventilation pipeline are arranged in the transverse bulkhead, and the transverse bulkhead structure comprises a vertical transverse bulkhead and a horizontal transverse bulkhead. And the arrangement direction of the main beams of the horizontally arranged transverse bulkhead is horizontal so as to optimize the structural weight. The structural characteristics of the LNG ship are considered, vertical arrangement and horizontal arrangement of the transverse bulkhead structure are mixed, practical application of the LNG ship is better facilitated in practice, and follow-up use convenience is improved.
Description
technical field [0001] The invention relates to ship building, in particular to a transverse bulkhead structure used on a large LNG ship. Background technique [0002] In modern social life, liquefied natural gas has become an indispensable energy source for life. The world's natural gas reserves are uneven, which requires high requirements for the transportation of liquefied natural gas. LNG carrier is the abbreviation of liquefied natural gas carrier. It liquefies natural gas at low temperature and stores it in a liquid form in the containment system, so that natural gas can be transported in large quantities. In the construction of new LNG ships, there are tank type and membrane type for the containment system of liquefied natural gas, and more and more shipowners adopt membrane type LNG ships. Now for the membrane containment system, for a new type of LNG carrier, it can achieve a storage capacity of 174,000 cubic meters. The transportation of such a large amount of l...
