Abstract: The method comprises supplying, at a construction site, of a functional module comprising a hybrid cooler; verifying onsite the exploitation of the equipment of the functional module; mounting the functional module on a support structure; moving the structure to an exploitation site on the expanse of water. The verification involves passing a flow to be cooled through the air cooler of the hybrid cooler, the flow being cooled exclusively by a flow of air circulating through the air cooler of the hybrid cooler. The exploitation of hydrocarbons on the expanse of water involves the passage of a flow to be cooled through the water cooler of the hybrid cooling system, the flow being cooled by heat exchange with water taken from the expanse of water circulating through the water cooler.

Abstract: A method for producing an LNG from natural gas, comprising



liquefaction of at least a first part of the natural gas in a first heat exchanger by heat exchange with a first mixed refrigerant fluid in a closed cycle,
sub-cooling of liquefied natural gas in a second heat exchanger by heat exchange with a second refrigerant fluid of a second refrigeration cycle,
expansion of the sub-cooled liquefied natural gas stream and admission into a flash gas separator,
withdrawal of liquefied natural gas at the bottom of the separator, and withdrawal, at the head, of a gas flow, and supply of the second refrigeration cycle by at least a part of said gas flow.
