A free-standing liner unit (1) is formed by integrating a planar outer tank liner plate (2), a planar secondary barrier plate (3), and a cold insulator layer (4) that is interposed between the outer tank liner plate (2) and the secondary barrier plate (3) into a single unit. According to this free-standing liner unit (1), when building a tank, it is possible to shorten the construction period by performing the formation of the outer tank shell plates and the formation of the tank internal structure concurrently with each other, and to achieve an improvement in the handleability of the free-standing liner unit (1).

An apparatus, system and method for capture, utilization and sendout of latent heat in boil off gas (BOG) onboard a cryogenic storage vessel is described. A liquefied gas vessel comprises a cryogenic cargo tank onboard a liquefied gas vessel, the cargo tank comprising a liquefied gas and a BOG, a latent heat exchanger fluidly coupled to a stream of the liquefied gas and a stream of the BOG, wherein the latent heat exchanger transfers a heat between the BOG stream and the liquefied gas stream to produce a condensed BOG, means for combining the condensed BOG and the liquefied gas stream to obtain a combined stream, the means for combining the condensed BOG and the liquefied gas stream fluidly coupled to the latent heat exchanger, and a liquefied gas regasifier onboard the vessel and fluidly coupled to the combined stream, wherein the liquefied gas regasifier regasifies the combined stream.

Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

A method for producing a sealed and thermally insulating wall for a fluid storage tank includes attaching plural anchoring elements to a support structure; installing modular formwork elements on the support structure, the modular formwork elements having a shape that protrudes relative to the support structure and that defines, with the support structure and the plurality of anchoring parts, compartments having an open side opposite the support structure; spraying insulating foam into the compartments through the open side to form plural insulating sectors made from sprayed insulating foam; arranging insulating junction elements in a stressed position in which they are stressed between the insulating sectors and capable of expanding when the insulating sectors contract, to ensure continuity of the thermal insulation; and attaching a sealing membrane to the anchoring elements.

The present invention relates to a method and an apparatus for storing liquefied gas in at least one insulated container (1) while withdrawing evaporated gas from one or more of the at least one container (1), wherein at least a part of the evaporated gas is supplied to a recondenser (11) and wherein liquefied gas is withdrawn from one or more of the at least one container (1) and at least in part supplied to the recondenser (11) for recondensing the evaporated gas supplied to the recondenser (11) such that recondensed gas is obtained at a recondenser outlet, wherein before supplying the iquefied gas to the recondenser (11), the liquefied gas is subcooled by passing it through a refrigeration unit (8, 9), at least a part of the subcooled liquefied gas being supplied to the recondenser (11), and wherein at least a part of the recondensed gas obtained at the outlet of the recondenser (11) is reintroduced into one or more of the at least one container (1).

A near shore liquefied natural gas (LNG) export terminal includes an LNG storage unit, a jetty and a converted hydrocarbon carrier-vessel moored against the jetty. The carrier-vessel includes a hull, at least one hydrocarbon storage tank and is provided with a natural gas processing system for liquefying natural gas. Onshore produced natural gas is supplied through a first pipeline to the natural gas processing plant on the carrier-vessel and the LNG produced by the natural gas processing system is transferred from the carrier-vessel to the LNG storage unit via a second pipeline suitable for the transfer of cryogenic fluids.

A sampling device having at least two inputs each configured to receive samples from a corresponding feedstock input line and a sample accumulator. The device also includes a mass flow controller associated with each feedstock input line, each mass flow controller having a sample output and being configured to receive a signal representative of the flow rate at each input, where each mass flow controller adjusts the flow rate of its respective sample from its respective sample output in response to receiving representative signals. Further the device includes at least a first and second sample output line respectively connected with a sample output of each mass flow controller, each sample output line being connected to an input of the sample accumulator for introduction to the sample accumulator of samples from the output of the mass flow controllers.
