The present invention includes: an independent tank constituting an inner tank to store a storage material therein; at least one sandwich plate modularized and manufactured include a metal plate provided in a pair opposite to each other, the metal plates having a reinforcing material formed therebetween, and a filler filled between the metal plates, the at least one sandwich plate surrounding the outer surface of the independent tank to constitute an outer tank; and an external reinforcing member formed on the outer surface of the sandwich plate.

A liquid gas vaporization and measurement system, and associated method, for efficiently vaporizing a continuous sample of liquid gas, such as liquid natural gas (LNG), and accurately determining the constituent components of the gas. A constant flow of liquid gas sampled from a mass storage device is maintained in a vaporizing device. Within the vaporizing device the liquid gas is flash vaporized within heated narrow tubing. The liquid gas is converted to vapor very quickly as it enters one or more independently operating vaporizer stages within the vaporizing device. The vapor gas is provided to a measuring instrument such as a chromatograph and the individual constituent components and the BTU value of the gas are determined to an accuracy of within +/0.5 mole percent and 1 BTU, respectively.

An LNG receiving structure (101) is provided with: a leader pipe (1) that is located below a receiving pipe (102) that penetrates a roof of an LNG tank, and extends as far as a bottom portion of the LNG tank; a hopper (2) that is provided at a top end of the leader pipe, and receives LNG expelled from the receiving pipe; a regulating component (3) that is provided inside the hopper, and regulates the flow of the LNG expelled from the receiving pipe such that this LNG flows down along an inside wall of the leader pipe; and a gas discharge port (4) that is provided in the hopper, and discharges to an outside of the hopper gas that has risen upwards from the leader pipe. By providing this LNG receiving structure, when a plurality of types of LNG that each have a different density are stored in the same LNG tank, it is possible to keep to a minimum any risk that rollover might occur.

A skid for capturing refrigeration from liquefied natural gas vaporization is disclosed comprising a first heat exchanger mounted on the skid, the first heat exchanger having a natural gas inlet, a natural gas outlet, a process fluid inlet, and a process fluid outlet. The process fluid is configured to flow from the process fluid inlet through the first heat exchanger to the process fluid outlet and then to the process fluid inlet. Other embodiments of the system for capturing refrigeration from vaporization of liquid natural gas, and methods for its use, are described herein.

A ship for bunkering liquefied fuel gas to a liquefied-fuel-gas propulsion ship includes: a liquefied-fuel-gas storage tank installed in the ship; a fuel supply pipe connected to the liquefied-fuel-gas storage tank and supplying fuel to the liquefied-fuel-gas propulsion ship; and a BOG collection pipe collecting BOG produced in a liquefied fuel gas tank of the liquefied-fuel-gas propulsion ship.

An impermeable and thermally insulated tank built into a load-bearing structure, the tank wall comprising: a thermally insulated barrier attached, to a load-bearing wall and made of insulating blocks, juxtaposed in parallel rows separated from one another, by gaps, an impermeable barrier supported by the thermally insulated barrier and made of welded metal sheets.

Each insulating block carries, on the face of same opposite the load-bearing wall, two metal connecting strips arranged in parallel to the sides of the insulating block. The sheets of the membrane carried by the insulating block are welded to the strips. The connecting strips are rigidly connected to the insulating block carrying same. The sheets each have at least two orthogonal folds parallel to the sides of the insulating blocks, the folds being inserted into the gaps formed between two insulating blocks.

This liquid hydrogen storage tank includes a tank body, a dike, a pump, and a housing chamber. The tank body includes an inner tank that forms a storage space for storing liquid hydrogen therein, and an outer tank that is formed by interposing a thermal insulation layer between the outer tank and the inner tank. The dike includes an outer peripheral surface and an inner peripheral surface that is in contact with the side plate of the outer tank. The dike is formed upwardly so as to surround the outer periphery of the tank body. The pump discharges liquid hydrogen inside the inner tank through the side plate of the inner tank to the outside. The housing chamber is disposed between the outer peripheral surface of the dike and the storage space, and houses the pump.

A blanket installation method includes: a transporting step of transporting a blanket unit (1), in which a blanket (2) and a transport jig (3) are integrally coupled, between an inner tank (60) and an outer tank (50) of a double shell structure tank in a suspended condition; and a mounting step of mounting the blanket unit (1) on a shell plate of the inner tank (60). The transport jig (3) is formed by attaching a blanket fixing pin (34) to a jig main body (3A) through pin coupling. The blanket (2) is held at the blanket fixing pin (34).

A regasification facility, regasification systems and methods for import, offloading and regasification of liquid natural gas from liquid natural gas carriers is provided. The regasification facility is configured to provide increased flexibility in the construction so as to enable substantial reductions in construction times and costs of the construction of the regasification facility to be constructed and brought into operation, and to be further scaled up quickly and efficiently versus traditionally constructed and operated land based regasification plants and/or floating storage and regasification units.

A sealed and insulating tank for storing and/or transporting a liquefied gas has a sealed and self-supporting internal reservoir with an interior surface for contacting the liquefied gas and an outer surface with an insulating barrier covering the outer surface of the internal reservoir. The insulating barrier is fixed to the internal reservoir. An outer sealed membrane covers an outer surface of the insulating barrier, and the outer sealed membrane has a metal sheet provided with bellows or corrugations. The outer sealed membrane is fixed to the insulating barrier or the internal reservoir. An intermediate space between the internal reservoir and the outer sealed membrane contains a gaseous phase under depression in order to press the outer sealed membrane against the outer surface of the insulating barrier.
