Abstract: A gas supply system for a high-pressure gas consuming appliance and a low-pressure gas consuming appliance of a floating structure including a tank containing the gas is disclosed. The supply system includes: a first supply circuit and a second supply circuit; a gas return line; and a first heat exchanger and a second heat exchanger configured to carry out a heat exchange between the gas of the first supply circuit and the gas circulating in the return line. The first supply circuit includes an additional pump.

Abstract: A method for supplying gas to a gas-consuming apparatus provided on a ship including a tank containing the gas in the liquid state and in the gaseous state, in which the method includes: supplying the gas-consuming apparatus with gas withdrawn in the gaseous state from the tank and by a supply unit; condensing at least a part of the gas withdrawn in the gaseous state from the tank by a condensation unit having at least one heat exchanger configured to perform a heat exchange between gas withdrawn between the supply unit and the gas-consuming apparatus and gas flowing between the tank and the supply unit; and cooling the heat exchanger prior to the condensing and at least partially simultaneously with the supplying.

Abstract: 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.

Abstract: The present invention primarily relates to a loading system (1) configured to transfer a cryogenic fluid (3) from a storage vessel (2) into a receiving vessel (4), the loading system (1) comprising at least one element (17) for circulating the cryogenic fluid (3) in the liquid state which connects the storage vessel (2) to the receiving vessel (4), a processing and/or consumption unit (26) of the cryogenic fluid (3) in the gaseous state originating at least from the receiving vessel (4) and a return line (28) of the cryogenic fluid in the gaseous state which connects the receiving vessel (4) with the processing and/or consumption unit (26), characterised in that the loading system (1) comprises at least one cooling unit (36) of the cryogenic fluid (3) circulating towards the receiving vessel (4) in the circulation element (17), the cold generated by the cooling unit (36) resulting from an evaporation of the cryogenic fluid (3) coming from the storage vessel (2).
