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.

Disclosed are a device and a method for bonding an auxiliary secondary barrier for an LNG storage tank. The device for bonding an auxiliary secondary barrier includes: a frame; a driving unit, a portion of which is arranged in the frame, and which enables the frame to move on an upper heat insulation board corresponding to an exposed portion of a main secondary barrier; an adhesive applying unit arranged in the frame to apply an adhesive on the exposed portion; an auxiliary secondary barrier supply unit arranged in the frame to supply an auxiliary secondary barrier on the adhesive applied on the exposed portion; and one or more heating unit arranged in the frame to heat at least one of the exposed portion to which the adhesive contained in the adhesive applying unit is to be applied and the auxiliary secondary barrier to be supplied on the applied adhesive.

A floating LNG storage barge with one or more LNG tanks provides mobile storage for LNG, by obtaining LNG from one or more LNG ocean transport vessels while the LNG storage barge is moored to a land-based jetty, transferring LNG to one or more land transfer trucks, pipelines or railroad tankers using an LNG distribution manifold and flexible hoses between the distribution manifold and the trucks via pumps or pressure differential between the LNG storage barge with the potential for LNG processing adaptive capacity.

Some embodiments relate to a storage system for liquefied natural gas (LNG). An example storage system for LNG comprises: a floatable vessel formed as a barge, the vessel including: a vessel frame, a hull around the vessel frame and defining fore and aft sections, and a deck supported by the vessel frame; at least two LNG storage tanks carried by the vessel frame. A first LNG storage tank may be positioned on a port side of the vessel and a second LNG storage tank may be positioned on a starboard side of the vessel. Fluid transport conduits connected to the at least two LNG storage tanks to allow fluid flow into and out of the at least two LNG storage tanks may be provided. A valve system to control flow of fluid in the fluid transport conduits may be provided. The vessel frame and the hull may define a broad and shallow draught.
