Problems solved by technology

[0005] The duration of the above-mentioned step of cooling the tanks is rather long, about 10 to 20 hours, which results in a considerable length of time for the ship to stop during its loading
Moreover, the amount of liquefied gas described in the cooling tank is large

Embodiment Construction

[0097] figure 1 The liquefied gas storage device 1 according to the first embodiment of the present invention is shown. The device 1 can be installed on land or on a floating structure. In the case of a floating structure, the device 1 can be used for liquefied natural gas carriers such as methane tankers, but can also be used for any ship that supplies propulsion devices, engine blocks, steam generators or any other consumable components through gas.

[0098] The device 1 includes a fluid-tight and thermally insulated liquefied gas storage tank 2. According to one embodiment, the tank 2 is a membrane tank capable of storing liquefied gas under atmospheric pressure. In particular, such a membrane tank includes a multi-layer structure including a secondary thermal insulation barrier, a secondary sealing film, a primary thermal insulation barrier, and a primary sealing film from the outside to the inside of the tank 2. The secondary thermal insulation barrier includes a thermal ...

Abstract

The invention relates to a method for the handling of liquefied gas cargo in a liquefied gas storage facility (1) comprising: a sealed and thermally insulating tank (2) for storing liquefied gas; a loading / unloading tower (3) comprising at least two vertical masts (7, 8, 9); and at least one unloading pump (6). The method comprises: a step of cooling the vertical masts (7, 8, 9), during which a liquefied gas flow is conveyed selectively towards each of the two vertical masts (7, 8, 9); and / or a step of cooling the unloading pump (6), during which a liquefied gas flow is conveyed selectively towards the unloading pump (6).

Description

Technical field [0001] The present invention relates to the field of storing cargoes of liquefied gas such as liquefied natural gas (LNG). [0002] The present invention particularly relates to a method of handling liquefied gas cargo and storing it in a liquefied gas storage device. Background technique [0003] In the prior art, known ships are equipped with devices for storing liquefied gas such as LNG, including a fluid-tight and thermally insulated storage tank for the liquefied gas and a loading / unloading tower suspended on the top wall of the tank. The loading / unloading tower of the tank includes a tripod-like structure, that is to say, it includes three vertical uprights, the uprights are connected to each other by cross beams, and each upright defines a cargo unloading and / or unloading route and / or backup well. The backup well can be lowered to the tank of the backup unloading pump and unloading route. The loading / unloading tower supports a pump for unloading cargo relat...
