Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.

Vessel assemblies, heat transfer units for prefabricated vessels, and methods for heat transfer prefabricated vessel are provided. A heat transfer unit includes a central rod, and a plurality of peripheral rods surrounding the central rod and connected to the central rod. The plurality of peripheral rods are movable between a first collapsed position and a second bowed position, wherein in the second bowed position a midpoint of each of the plurality of peripheral rods is spaced from the central rod relative to in the first position. The heat transfer unit further includes a heat transfer element connected to one of the plurality of peripheral rods.

The device (100) for providing liquefied natural gas, referred to as LNG, comprises: an evaporation gas buffer tank (105) comprising an inlet (110) for evaporation gas suitable for receiving evaporation gas from a third-party device, a member (115) for transferring evaporation gas from the buffer tank to an LNG storage capacity (120), downstream from the transfer member (120), a compressor (140) for compressing the evaporation gas, an evaporation gas transfer pipe (125) for transferring evaporation gas from the transfer member to the storage capacity, the LNG storage capacity, an LNG transfer pipe (130) for transferring LNG from the storage capacity to a third-party device and a heat exchanger (135) for exchanging heat between evaporation gas passing through the evaporation gas transfer pipe and LNG passing through the LNG transfer pipe configured to liquefy or cool the evaporation gas.

A cryogenic storage vessel having an inner vessel defining a cryogen space; an outer vessel spaced apart from and surrounding the inner vessel, defining a thermally insulating space between the inner vessel and the outer vessel; and a receptacle defining passages for delivery of liquefied gas from the cryogen space to outside the cryogenic storage vessel. The receptacle has an elongated outer sleeve defining an interior space in fluid communication with the thermally insulating space that is sealed from the cryogen space; an elongated inner sleeve extending into the interior space defined by the elongated outer sleeve defining an inner receptacle space that is fluidly isolated from the thermally insulating space; and a collar extending around an inner surface of the elongated inner sleeve which seals against a cooperating surface of a pump assembly when a pump assembly is installed in the cryogenic storage vessel thereby dividing a warm end from a cold end of the receptacle. A motor for driving the pump can be installed within the cryogenic storage vessel.

The present invention is to properly manage life of an accumulator and extend the life of the accumulator. A gas supply system includes a control section, an acquiring section, a classifying section, and a judging section. The acquiring section acquires stress amplitude of accumulators from a pressure difference between first pressure on the gas storage side and second pressure on the gas lead-out side. The classifying section classifies the stress amplitude into a plurality of groups. The judging section divides the calculated acquirement number n.sub.i of the stress amplitude for each of the groups by the predetermined breaking cycle number N.sub.i, and determines a fatigue degree n.sub.i/N.sub.i. In a case where this value becomes a predetermined threshold value or more, the judging section judges that the accumulator comes to the end of the life.

A fire engine including a vehicle frame, a liquid nitrogen storage tank, a liquid nitrogen conveying pipeline, a gasification device, a plurality of electric valves, a water pipe adapter, a liquid nitrogen spray gun, and a mixed spray gun. The liquid nitrogen conveying pipeline includes a first pipeline and a second pipeline. The first pipeline connects the lower part of the liquid nitrogen storage tank, the gasification device, and the upper part of the liquid nitrogen storage tank sequentially in that order. The second pipeline connects the liquid nitrogen storage tank, an input end of the liquid nitrogen spray gun, and a first input end of the mixed spray gun. The mixed spray gun includes a first input end, a second input end, a liquid nitrogen nozzle, and a spray pipe. The spray pipe includes a contraction section, an expansion section, and an acceleration section.

An apparatus includes a Dewar having an endcap. The apparatus also includes a heat sink and a multiaxial thermal shoe having a thermal interface material and configured to thermally couple the endcap of the Dewar to the heat sink via one of at least two axial surfaces. The multiaxial thermal shoe is configured to transfer thermal energy between the endcap of the Dewar and the heat sink without structurally coupling the Dewar to the heat sink. The multiaxial thermal shoe may be configured to hold the thermal interface material against the endcap. The multiaxial thermal shoe may couple to the heat sink via a first axial surface in-line with an optical centerline or a second axial surface crosswise to the optical centerline.
