Abstract: A floating plant for liquefying natural gas having a barge provided with a liquefaction plant, member for receiving natural gas and with member for storing and discharging liquefied natural gas. The liquefaction plant involves a heat exchange in which heat is removed when liquefying natural gas is transferred to water. The barge is further provided with a receptacle; an open-ended water intake conduit having an inlet; a connecting conduit extending from the outlet of the water intake conduit to the receptacle; a pump for transporting water from the receptacle to the heat exchanger and a water discharge system for discharging water removed from the heat exchanger. The connecting conduit has the shape of an inverted “U” of which the top is located above the receptacle.

Abstract: Plant for liquefying natural gas comprising a main heat exchanger in which the natural gas is liquefied by means of indirect heat exchange with evaporating refrigerant, and a refrigerant circuit in which evaporated refrigerant is compressed and liquefied to produce liquid refrigerant that is used in the main heat exchanger, wherein the refrigerant circuit includes a compressor train consisting of at least one compressor driven by an electric motor.

Abstract: A floating plant for liquefying natural gas comprising a barge (2) provided with a liquefaction plant (3), means for receiving natural gas and with means for storing and discharging liquefied natural gas, which liquefaction plant (3) includes a heat exchange (12) in which heat removed when liquefying natural gas is transferred to water, which barge (2) is further provided with a receptacle (20), an open-ended water intake conduit (25) having an inlet (28), a connecting conduit (35) extending from the outlet (30) of the water intake conduit (25) to the receptacle (20), a pump (40) for transporting water from the receptacle (20) to the heat exchanger (12) and a water discharge system (45) for discharging water removed from the heat exchanger (12), wherein the connecting conduit (35) has the shape of an inverted “U” of which the top (47) is located above the receptacle (20).

Abstract: Plant (1) for liquefying natural gas comprising a main heat exchanger (10) in which the natural gas (5) is liquefied by means of indirect heat exchange with evaporating refrigerant, and a refrigerant circuit (20) in which evaporated refrigerant is compressed (23a, 23b) and liquefied to produce liquid refrigerant that is used in the main heat exchanger (10), wherein the refrigerant circuit (20) includes a compressor train (23a, 23b) consisting of at least one compressor (65a-67b) driven by an electric motor (83a, 83b).
