A system supplies gas to a high-pressure gas-consuming apparatus and a low-pressure gas-consuming apparatus of a floating structure including a tank. The supply system includes: a first supply circuit, a second supply circuit, a return line, a first heat exchanger and a second heat exchanger. The return line includes a flow-regulating member. The supply system includes a device for managing the supply system which includes a control module to control the flow-regulating member based on the characteristics of the gas.

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.

The invention relates to a sealed and thermally insulating tank for storing fluid, comprising, from the outside to the inside of the tank, a secondary thermally insulating barrier and a secondary sealing membrane, the secondary sealing membrane being secured to the secondary thermally insulating barrier, a primary thermally insulating barrier resting against the secondary sealing membrane and a primary sealing membrane resting against the primary thermally insulating barrier, the tank comprising a duct that extends along a longitudinal direction, the duct being delimited on one hand by the secondary thermally insulating barrier and on the other hand by the secondary sealing membrane, a bottom of the duct being at least in part formed by the secondary thermally insulating barrier, the tank further comprising a pressure-drop stopper that is arranged in the duct and extends between the bottom of the duct and the sealing membrane.
