A storage system for storing a cryogenic medium, in particular, for storing hydrogen. The storage system includes storage container for receiving the cryogenic medium, at least one pipe projecting from outside the storage container into the storage container, and a shut-off valve in fluidic communication with the at least one pipe. The at least one pipe is closed at an end thereof facing away from the storage container and is open at another end thereof located in the storage container. The shut-off valve is moveable between an open operating state in which an inner space of the at least one pipe is in fluidic communication with an inner space of the storage container, and a closed operating state in which the inner space of the at least pipe is not in fluidic communication with the inner space of the storage container.

An assembly for storing and transporting compressed fluid, such as compressed natural gas (CNG) that includes; a plurality of hexagonally stacked pipe stored in a cargo hold in or on a vessel, such as a ship or barge, that includes a lower support, side supports and a forcing mechanism that presses so strongly down on the pipes that they cannot move relative to themselves or relative to the vessel on which they are placed in any service situation. The friction between each of the pipes causes the plurality of pipes to act as part of the vessel in terms of its structure. Each of the pipes in the plurality of pipes is connected to a manifold system to allow or the loading and unloading of the compressed fluid.

The present invention relates to a gas treatment system and a ship including the same. The gas treatment system treats liquefied gas as heavier hydrocarbons or ammonia. The gas treatment system includes: a fuel tank storing liquefied gas as a fuel to be supplied to a propulsion engine of a ship; a liquefied gas supply line supplying the liquefied gas of the fuel tank in a liquid phase to the propulsion engine, the liquefied gas supply line having a high pressure pump provided thereon; a reliquefaction apparatus liquefying boil-off gas generated in a cargo tank storing liquefied gas; and a liquefied gas collection line collecting the liquid liquefied gas discharged from the propulsion engine upstream of the high pressure pump. The reliquefaction apparatus transfers the liquefied boil-off gas to the fuel tank, thereby allowing the liquefied boil-off gas to be supplied to the propulsion engine by the high pressure pump.

Methods of, and control systems for, operating modular, liquid natural gas (LNG) manifold apparatuses, crossover systems for such modular manifold apparatuses, and systems including one or more of the modular manifold apparatuses and a plurality of ISO tank containers. The modular manifold apparatus includes an ISO container (e.g., an open-frame ISO container) with a plurality of container connection sections or bays, a liquid system, and a vent system, where each of the liquid and vent systems includes a header and a plurality of connection lines configured to be coupled to the respective liquid and vent connections of LNG containers adjacent the modular manifold apparatus.

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 discharged from a storage tank as a refrigerant; a bypass line through which the BOG is supplied to the compressor after bypassing the heat exchanger; a second valve disposed on a second supply line through which the BOG used as the refrigerant in the heat exchanger is supplied to the compressor, the second valve regulating a flow rate of fluid and opening/closing of the second supply line; and a pressure reducer disposed downstream of the heat exchanger and reducing a pressure of fluid cooled by the heat exchanger, wherein the compressor includes at least one oil-lubrication type cylinder and the bypass line is joined to the second supply line downstream of the second valve.

A storage tank for liquid hydrogen having an outer tank , an inner tank which is arranged inside the outer tank , and a device for indicating a predefined fill level has been reached with a cell which can be arranged inside the inner tank and is filled with a gas which liquefies when the cell is dipped into the liquid hydrogen , further having a pressure indicator device which indicates a pressure drop in the cell in the case of liquefaction of the gas and therefore indicates the predefined filling level has been reached, and further having a heating element which continuously introduces heat into the gas .

Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

A liquefied fuel cryogenic tank has an inner jacket delimiting a fluid storage volume and an outer jacket disposed around the inner jacket with a vacuum thermal insulation gap therebetween. A withdrawal circuit has an assembly of one or more valves and a withdrawal line that has a first heating heat exchanger located outside the inner jacket and a second heating heat exchanger located inside the inner jacket. Fluid flows through the withdrawal line via the first heat exchanger and then the second heat exchanger or via the first heat exchanger without entering the second heat exchanger.
