Disclosed herein is a BOG reliquefaction system for LNG vessels. The BOG reliquefaction system includes a compressor compressing BOG, a heat exchanger cooling the compressed BOG by exchanging heat between the compressed BOG and BOG used as a refrigerant, and an expansion unit for expanding the BOG having been cooled by the heat exchanger, wherein the heat exchanger includes a core, in which heat exchange between a hot fluid and a cold fluid occurs, the core including a plurality of diffusion blocks, and a fluid diffusion member diffusing a fluid introduced into the core or a fluid discharged from the core.

A device for transferring a fluid from a supply tank to a receiver tank includes at least one duct for charging the receiver tank with liquid and at least one duct for return of the gas. The gas return duct is configured to transfer the gas contained in the receiver tank at a pressure close to or significantly different from the pressure of the supply tank.

Implementations of the present disclosure generally relate to an apparatus for large-scale external pressure storage, and more particularly for large-scale storage of liquid hydrogen and other products that require evacuated insulation. In some examples, a plate for a storage apparatus is provided. The plate a body that includes a beveled joint with the body having a nominal thickness at the beveled joint. The beveled joint is configured to be welded to a corresponding beveled joint of an adjacent plate.

A tank is used in the containment, transport, and/or storage of fluids, e.g., one or more liquids and/or gases. In one embodiment, the tank includes a plurality of segments collectively defining an interior chamber that retains the fluid(s), each of which includes opposing ends defining beveled mating surfaces. The tank also includes a plurality of endcaps positioned between, and in engagement with, adjacent segments, as well as a plurality of webs that include a series of first webs having a first configuration and a series of second webs having a second, different configuration. The first webs are positioned within the plurality of segments between the ends thereof, and the second webs are positioned within the endcaps. In an alternate embodiment, the tank is devoid of the endcaps, and instead, includes segments defining beveled mating surfaces that intersect at junctures to define four corner sections of the tank.

An object to provide a vent pipe isolation balloon for a liquefied gas storage tank, which has excellent physical strength, inflatability, and durability at cryogenic temperatures, and a vent pipe isolation device including the balloon. The vent pipe isolation balloon has inner and outer membranes made of silicon rubber, and a reinforcing substrate sandwiched between the inner membrane and the outer membrane. The balloon has an outer shape of a cylindrical shape or a truncated cone shape with both ends opened, and is inflated when an inert gas is injected into the balloon with the openings sealed. The reinforcing substrate is composed of a fiber bundle and has a network structure.

The present invention relates to a computer-implemented method and system for computing a transition parameter of a liquefied gas storage medium, the storage medium having at least one sealed and unrefrigerated tank, the transition parameter characterizing an evolution of a two-phase mixture contained in the sealed and unrefrigerated tank between an initial state and a final state, the two-phase mixture including a liquid phase and a vapour phase, the transition parameter may be a duration of the transition, a liquid bleeding rate or a vapour bleeding rate.

A storage system is provided that includes a primary container, a first insulation layer, a secondary container, a secondary bottom, and a second insulation layer. The primary container has a primary bottom. The first insulation layer is disposed below the primary bottom. The secondary bottom is disposed below the first insulation layer and the secondary container. The secondary bottom has an expansion joint configured to permit the secondary bottom to expand and/or contract independently from the secondary container. The second insulation layer is disposed below the secondary bottom. In the event of LNG leaking from the primary container, the second insulation layer is protected from LNG contact by the secondary bottom. The carbon steel liner located on the outside face of the concrete wall remains vapor tight and liquid tight in the event of any amount of LNG leaking from the primary container.

The present invention relates to a system (100) for supplying gas to at least one gas-consuming appliance (300) equipping a ship (70), the supply system (100) comprising at least: one gas supply line (123) for supplying gas to the at least one gas consuming appliance (300), said gas supply line being configured to be traversed by gas taken in the liquid state from a tank (200) and subjected to a pressure lower than a pressure of the gas in a headspace (201) of the tank (200), a first compression member (120) configured to compress the gas from the gas supply line (123) for supplying gas to the at least one gas-consuming appliance (300), a second compression member (130), characterised in that the first compression member (120) and the second compression member (130) alternately compress gas in the gaseous state from the gas supply line (123) and gas taken in the gaseous state from the headspace (201) of the tank (200).

A hydrogen tank for aircraft, including an inner vessel configured to contain hydrogen, first and second outer jacket domes having a semi-spherical shape and first L-shaped ends, a first cylindrical outer jacket established on top of the first and second outer jacket domes, a second cylindrical outer jacket established in the bottom of the first and second outer jacket domes.
