The invention primarily concerns a facility for storing and cooling a liquefied gas, for example a liquefied natural gas, the facility comprising at least one tank configured to contain the liquefied gas, a closed cooling circuit configured to be supplied with liquefied gas in the liquid state coming from the tank, at least one injection member configured for reinjecting cooled liquefied gas into the tank, the facility being characterized in that it comprises at least one connection line configured to recover a cooled gas from at least one remote container that is separate and independent from the facility.

A liquefied gas storage tank according to an embodiment of the present invention may comprise: a tank unit in which liquefied gas is stored; an inner box unit disposed inside the tank unit and installed at the bottom portion of the tank unit; and a pump unit that has an inlet pipe part formed to pass through a lower wall portion of the inner box unit and communicate with the inside of the inner box unit, and suctions the liquefied gas stored in the tank unit through the inlet pipe part, thereby supplying the liquefied gas to the outside.

An insulation arrangement for an ocean-going ship comprising a modular arrangement of panels, each panel comprising a first cold layer and an opposing ambient layer and a volume therebetween arranged in use to be evacuated to create a vacuum.

A membrane finishing sheet, which is disposed at a membrane finishing part among multiple membrane sheets which form a sealing wall installed at a membrane type cargo, comprises a corrugated part having a structure closed in a direction toward the membrane finishing part. In addition, a membrane insulation structure comprising a membrane finishing sheet according to the present invention comprises a membrane finishing sheet disposed at a membrane finishing part among multiple membrane sheets which form a sealing wall installed at a membrane type cargo. Among four sides of the membrane finishing sheet, a finishing side in contact with the membrane finishing part has a structure in which the corrugated part is closed and thus provides a membrane insulation structure that does not require a separate finishing member for sealing a membrane.

A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

The invention relates to a method for providing pressurized gas from a source of liquefied gas to a consumer (8), wherein vaporized gas is supplied from the source of liquefied gas (1) through a main input line (2) to a compressor arrangement (300) for pressurizing the vaporized gas, the compressor arrangement (300) comprising a plurality of compressor modules (3, 5, 31, 51), each compressor module being able to operate independently from any other compressor module of the compressor arrangement (300), one or more of the compressor modules (5, 51) of the compressor arrangement (300) can be bypassed, and wherein gas is conducted through only a part or all of the compressor modules depending on at least one of pressure level, temperature level, mass flow and composition of the gas to be provided to the consumer (8).

Disclosed is a BOG reliquefaction system. The BOG reliquefaction system includes: a compressor compressing BOG; a heat exchanger cooling the BOG compressed by the compressor through heat exchange using BOG not compressed by the compressor as a refrigerant; a pressure reducer disposed downstream of the heat exchanger and reducing a pressure of fluid cooled by the heat exchanger; and a second oil filter disposed downstream of the pressure reducer, wherein the compressor includes at least one oil-lubrication type cylinder and the second oil filter is a cryogenic oil filter.

Composite tank apparatus and methods of making and using same. An array of flat-sided co-dependent cells with relatively thin skins made of metallic or non-metallic materials. Each cell has at least two flat wall panel portions connected by radiused sections arranged such that all of the flat wall panel portions are either in flush contact with each other or in flush contact with flat supporting panels of an enclosing structure or thermal insulating material lining an interior thereof. The cells are sealed with each other around a perimeter of at least one pair of matching lightening through-wall holes provided in adjacent pairs of the wall panel portions of the cells to resist relative movement and prevent leakage of fluid therefrom. The composite tank apparatus may include an enclosing structure, and optionally, one or more layers of thermally insulating material lining the interior surface or the exterior surface of the enclosing structure.

A vessel for the transport of liquefied gas has a hull, a cargo storage tank arranged in the hull for storing liquefied gas and an engine to propel the ship. A compressor has a compressor inlet connected to a vapour space of the at least one cargo storage tank for receiving boil-off gas at a first pressure and a compressor outlet for supplying pressurized boil-off gas to the at least one engine at a second pressure exceeding the first pressure. A boil-off gas recovery system is provided for recovery of boil off gas. The boil-off gas recovery system has a cooling section with a cooling section inlet connected to the compressor outlet to recondense at least part of the pressurized boil-off gas and a boil-off gas storage tank having a boil-off gas storage tank inlet connected to the cooling section outlet for storing the recondensed pressurized boil-off gas.

A cryogenic liquid storage system is provided that includes a primary container, an insulation portion, a secondary container, and a pressure release feature. The primary container includes a metal sidewall and a metal dome. Alternatively, the primary container may be constructed out of composite material. The primary container may be configured to retain liquid hydrogen. The insulation portion covers the primary container. The secondary container includes a composite material that covers each of the primary container and the insulation portion. The pressure release feature is disposed through each of the primary container dome, the insulation portion, and the secondary container dome.
