The invention relates to a tank for cold or cryogenic liquids having a double casing made of light metal, a base, lateral walls and a cover which defines the tank chamber. The double casing comprises an inner barrier, an outer barrier which is arranged at a distance from the inner barrier and structures which join the inner barrier to the outer barrier, at least one distribution pipe having holes through which the gas can flow for distributing inert gas in the intermediate chamber, said distribution pipe being arranged in the intermediate chamber between the inner barrier and the outer barrier of the tank base, at least one feed pipe for inert gas which is arranged outside of the double casing, which is connected in a communicating manner to the distribution pipe through the outer barrier, an inert gas source connecting to the feed pipe outside of the tank casing, a gas outlet from the intermediate chamber in the outer barrier of the tank cover and means for detecting gas in the region of the gas outlet.
摘要:
The invention regards a tank for storing of fluid at very low temperature, as LNG, which tank comprises external plates, forming roof, side walls and floor, and an internal cell structure with fluid communication between all the cells in the cell structure at floor level of the tank. At least a part of the external plate comprises a layered structure and where the internal cell structure is formed as self equilibrating support and or anchoring for the external plates. The invention also regards a cell structure for use in a tank for storing fluid.

A container is provided for storing pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 °C (-190 °F) to about -62 °C (-80 °F). The container is constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 °C (-100 °F).

The invention relates to a method for fabricating a sealing barrier for a sealed and thermally insulating vessel wall, comprising the steps of: arranging a repeating structure comprising alternately a sheet metal strip and an elongate welding flange (9) connected to the supporting surface, such that the raised lateral edges (20) of the sheet metal strip are arranged against the adjacent welding flanges; welding the raised lateral edge (20) to the welding flange using a straight weld bead (26) along a first longitudinal portion (27); extending the straight weld bead by an end portion (28, 29) diverted toward an upper edge (32, 41, 43); and performing a sealed edge weld (31) along a second longitudinal portion of the sheet metal strip such that the edge weld (31) sealingly joins the end portion (28, 29) of the weld bead (26).
摘要:
The present invention provides an assembly of orthogonal tension beams (4) in alternate horizontal layers for use in a tank, wherein at least some of the intersection points between the orthogonal tension beams are interconnected by vertical spacer elements (5) with bending stiffness and torsional flexibility as well as spacer elements suitable for said assembly.

The invention relates to a device for storing an independent tank (2) for cryogenic media, particularly LNG, in a vertical position in a ship (1) or a stationary facility (1). The device comprises a support for the tank (2), which supports the tank (2) on a corresponding foundation (10) of the ship (1) or the facility (1) through a thermally insulating layer (7) and which enables a horizontal relative motion between the tank (2) and the foundation (10).
摘要:
Pressure vessel made of aluminium for transport and storage of fluids. The vessel comprises two mainly semi-spherical, forged parts (2), that are joined together along their periphery by means of plasma welding. Each semi-spherical part is provided with a boss (4) that is formed under the forging operation, one or both of the bosses may be provided with passing bores (5) having internal threads for attaching a valve/valves thereto. Further, one or both of the bosses may be equipped with external threads for the attachment of protective caps (8), or one protective cap and a support leg.
