Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0045] like figure 1 As shown, the water transportation system of the offshore LNG storage tank provided by the present invention includes an LNG storage module 1, a tugboat 2 and 6 steel cables 3; as Figure 2-Figure 4As shown, the LNG storage module 1 in the present invention includes a tank foundation and a caisson structure arranged on the tank foundation; the tank foundation is a cavity structure with an opening at one end surrounded by a roof 4 and a skirt 5, The top plate 4 is made of reinforced concrete, and the skirt plate 5 is made of steel plate. A plurality of evenly arranged open cabins 6 are arranged in the cavity structure, and a plurality of air valves (not shown in the figure) are arranged on the skirt plate 5, and the air valves communicate with the open cabins 6 so as to facilita...

Abstract

The invention discloses a water transportation system for a marine LNG (Liquefied Natural Gas) storage tank. The water transportation system comprises an LNG storage module, a power traction device and at least four cables, wherein the LNG storage module comprises a box cylindrical foundation and a caisson structure arranged on the box cylindrical foundation; the box cylindrical foundation is of a cavity structure which is formed by encircling a top plate and a skirting board and has an open end; the cavity structure is internally provided with multiple open cabins; the skirting board is provided with multiple air valves communicated with the open cabins; the caisson structure comprises a caisson bottom plate, caisson sidewalls and a caisson top plate; the caisson bottom plate, the caisson sidewalls and the caisson top plate are connected to form a cavity; the cavity is used for bearing the LNG storage tank; the caisson bottom plate is arranged on the top plate; the two ends of each cable are respectively connected to the LND storage module and the power traction device. The water transportation system for the marine LNG storage tank, on one hand, can reduced the gravity center of a floating transportation part per se, and on the other hand, can reduce a functional area of a horizontal load and can well avoid the risk of structure instability.

Description

technical field [0001] The invention relates to a water transport system for an offshore LNG storage tank, belonging to the technical field of liquefied natural gas (LNG) transmission and distribution. Background technique [0002] LNG land receiving terminals are facing problems such as the reduction of available shorelines, lack of land areas, and high environmental requirements. The development of engineering construction of LNG water receiving terminals is an important way to solve these problems. According to different structural types, LNG water receiving terminals can be divided into two categories: floating type and fixed type. Most of the current LNG water receiving terminals are floating, which use gasification facilities installed on LNG carriers, and then go ashore through submarine pipelines. For fixed receiving terminals, only ExxonMobil has completed a LNG offshore fixed receiving terminal project GBS (Gravity Based Structures). Ing.PaulVSullivan and PaulMayn...
