Embodiment Construction

[0088] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0089] ginseng figure 1 As shown, the marine liquid cargo storage tank includes an intermediate tank body 1, a left tank body 2, and a right tank body 3 arranged side by side. The left tank body 2 and the right tank body 3 are symmetrically located on both sides of the intermediate tank body 1, and the intermediate tank body The two sides of 1 respectively form a vertical joint surface with the left tank body 2 and the right tank body 3, and the mediastinal com...

Abstract

The application discloses a marine cargo tank storage tank. The marine cargo tank storage tank comprises a middle tank body, a left tank body and a right tank body, which are arranged in parallel, wherein the left tank body and the right tank body are symmetrically positioned on two sides of the middle tank body; vertical joint surfaces are respectively formed between one side of the middle tank body and the left tank body and between the other side of the middle tank body and the right tank body; longitudinal compartments are arranged on the joint surfaces; and the interiors of the middle tank body, the left tank body and the right tank body are communicated through via holes in the longitudinal compartments. The marine cargo tank storage tank has the advantages that in the same cabin, compared with a two-body tank, a three-body tank has the advantages that the space utilization rate is improved by 7.8%-17.5%; the three-body tank is adopted to improve the single-strip carrying capability of an LNG transport ship greatly, and more values are created; and the three-body tank is provided with the two longitudinal compartment walls, so that the lateral shaking impact on a small liquid tank can be effectively reduced, the fatigue rupture is reduced, the safety of the compartment walls and a ship body structure is ensured, and the service life of the liquid tank is prolonged.

Description

technical field [0001] The present application relates to a marine LNG storage tank, in particular to a marine cargo tank storage tank. Background technique [0002] Liquefied Natural Gas (LNG for short) is favored as a green energy source. There are two ways to transport LNG, pipelines and transport ships. With the wide application of natural gas, the demand for LNG carriers is very strong, and its development and research has become a hot issue today. The liquid cargo tank is the core equipment of the LNG carrier, and the form of the storage tank has a great influence on the design of the LNG transportation. There are two types of storage tanks for LNG carriers in the world today: membrane type and independent type. [0003] The film type can be divided into two types: Technigaz and Gaz-Transport. The inner wall of the former cargo hold is corrugated. Its characteristics are: many prefabricated parts can be processed, and the shipbuilding time is shortened. Due to the t...
