Problems solved by technology

At lower temperatures as occurs in liquefied natural gas, said known structures are limited, more precisely due to the temperature itself and additionally due to the large thermal expansion of the storage tank material which must be used for freezing liquefied gas coefficient

Embodiment Construction

[0023] Figure 1 shows a simplified cross-sectional view of a hull 1 with a device for supporting a bilobed storage tank 3 according to the invention. The section plane shown is perpendicular to the longitudinal axis of the vessel.

[0024] The double-leaf tank 3 has a cross-section consisting of two arc segments. The storage tank 3 rests on two or more saddles 6, one of which is shown in FIG. 1 . The saddle 6 is firmly connected with the storage tank 3, preferably welded together. The base 4 is arranged in the hull 1 and is firmly connected with the hull. A heat insulating layer 8 is provided between the flat upper side 5 of the base 4 and the flat lower side 7 of the saddle 6 . This insulating layer 8 transfers the weight of the tank and its contents to the base 4 . The thermal insulation layer 8 is preferably at least partially made of laminated sheet material. This insulating layer is firmly connected to the flat lower side 7 of the saddle 6 and slides on the flat uppe...

Abstract

Disclosed is a device for mounting a tank in a ship (1). Said device comprises at least two foundations (4) which are fastened to the hull at a distance from each other in the longitudinal or transversal direction of the ship (1) and each of which supports one saddle (6) that is adapted to the shape of the tank (3) and is used for accommodating the tank (3). The inventive device further comprises an insulating layer (8) that is provided on each saddle (6) to thermally insulate the foundations (4) relative to the tank (3) as well as safety mechanisms (10; 12; 15) for mounting the tank (3) on the foundations (4), said safety mechanisms (10; 12; 15) allowing a relative movement between the tank (3) and at least one foundation (4) on the insulating layer (8) in the longitudinal direction of the tank. Each saddle (6) is fastened directly to the tank (3) and has a planar bottom face (7) while each foundation (4) has a planar top face (5), all bottom and top faces (7; 5) being parallel to one another. The insulating layer (8) is disposed between the bottom face (7) of the saddle (6) and the top face (5) of the associated foundation (4) while the safety mechanisms (10; 12; 15) allow a limited relative movement between each saddle (6) and the foundation (4) thereof on or in the insulating layer (8).

Description

technical field [0001] The invention relates to a device for supporting individual storage tanks for liquefied gas, in particular LNG, in a vessel according to the preamble of claim 1, and a bilobe especially suitable for said device pressure tank. Background technique [0002] For the transport of liquefied gas in ships, especially ocean-going vessels, there are traditionally various solutions. In each case involves the thermal insulation of containers for cryogenic or refrigerated liquefied gases within the vessel relative to the hull of the vessel, while at the same time establishing a connection between the vessel and the hull of the vessel which withstands the loads of the load and the occurrences during travel Acceleration below 1.5g. In addition to integral storage tanks, thin metal storage tanks and semi-thin metal storage tanks (Semi-Membrantanks), independent storage tanks for liquefied gas are also used, which are themselves mechanically stable independently of ...
