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.

Systems and methods for transporting and managing LNG are contemplated. A source of LNG is pumped to a pressure higher than a consumer pressure, and is vaporized to provide vaporized LNG. The vaporized LNG is transported from a first location to a second location without the need for cryogenic equipment. At the second location, the vaporized LNG is expanded to the consumer pressure or a second pressure below the consumer pressure to generate refrigeration content suitable to reliquefy at least a portion of the vaporized LNG. A reliquefied natural gas is generated at the second location while providing a natural gas product to a downstream consumer at the consumer pressure.

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 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.
