Definitions
- the present invention relates to a tank system for liquefied gas, of the type on board a ship or other floating structure.
- Liquefied natural gas or LNG is mainly composed of methane.
- the invention also applies to liquefied petroleum gas, and any combustible liquefied gas.
- Liquefied natural gas can be shipped aboard a ship to be transported, it is called LNG carrier or LNG carrier.
- the liquefied natural gas can be shipped to form the, or at least one of the fuel propelling ships of any type, for example container carriers. This is called an LNG fueled ship or LFS.
- the invention applies more particularly to floating structures of this second category.
- Liquefied natural gas in that it has complete combustion, is much less polluting than conventional fuels such as gasoline or gas oil. Liquefied natural gas has a high mass energy and because of its liquefaction, providing a high compression, a large volume energy. Also, liquefied natural gas is becoming an advantageous alternative for the propulsion of ships.
- a ship 10 comprises, in a known manner, a first bridge 11 or an upper deck, which may notably be designed to carry a payload C and / or cabins and living spaces for passengers.
- a tank 1 intended to contain combustible liquefied gas comprises at least one incoming pipe 2 (loading or filling) and at least one outgoing pipe 3 (unloading or drawing). These pipes 2, 3 typically connect the tank 1 to a management device 7 which interfaces with both gas suppliers and consumers / users.
- a typical consumer is the propulsion motor 45 of the ship.
- An example of the management device 7 is described in the publication FR-A-3004513.
- connection device 5 or "Tank Connection Space” in English or TCS.
- the "IGF code” regulation still recommends the presence of a cofferdam of at least 900 mm between the vessel 1 and the management device 7.
- a cofferdam or dry mesh is a confined volume, substantially empty, allowing a physical segregation between a zone presenting a risk of fire such as the management device 7 and an area to be protected such as the tank 1.
- An idea underlying the invention is to provide a structure that meets these various constraints, while facilitating installation.

- the or each pipe comprises a primary pipe having one end immersed in the vessel and a secondary pipe having one end connected to said isolation valve, the other end of the primary pipe being joined to the other end of the secondary pipe.
- the assembly of the primary pipe to the secondary pipe can be achieved by an assembly means which comprises a flange or a sleeve, or by welding the two pipes end to end.
- the assembly means may be disposed outside or inside the sealed enclosure.
- the assembly means may be wrapped in an independent sealed enclosure and separated from the sealed enclosure which contains the isolation valves.

- metal stiffeners may be attached to a lower surface of the first bridge.
- the metal membrane (s) may have a thickness of, for example, between 0.5 mm and 3 mm, preferably between 0.7 and 1.5 mm. Examples of such metal membranes are known for example in the applicant's N096® and Mark III® technologies.

- the enclosure is designed to reliably withstand the most extreme temperature conditions to which it may be subjected during operation.
- the enclosure is provided with a forced ventilation device by extraction, for example with a flow rate greater than 30 times its internal volume per hour.
- the enclosure may contain a vaporization unit connected to a pipe, including a drawing pipe, and configured to vaporize a flow of liquefied gas pumped into the tank to a gas consuming member.
- a gas compressor for conveying gas to the consumer member may be provided in the management device, preferably outside the sealed enclosure.

- a judicious use of the upper bridge 11 and the carrier wall 12 and mainly the space between them advantageously makes it possible to produce the required cofferdam.
- the carrier wall 12 is preferably a steel wall provided with stiffeners 47 on the upper side facing the cofferdam.
- the presence of the stiffeners 47 on the top of the carrier wall 12 makes it possible to leave the lower surface substantially flat and free of obstacles in order to be coated with a multilayer structure forming the sealed and thermally insulating tank wall.
