Containerised LNG liquefaction unit and associated method of producing LNG

A containerised liquefied natural gas (LNG) liquefaction unit comprising:

• a LNG liquefaction plant comprising a main cryogenic heat exchanger (MCHE) that is configured to liquefy a feed stream gas, and a closed loop refrigerant circuit that passes through the main cryogenic heat exchanger;
• a transportable container, wherein at least the main cryogenic heat exchanger (MCHE) and the closed loop refrigerant circuit of the LNG liquefaction plant are wholly contained within the transportable container, the transportable container being hermetically sealed;
• and
• a plurality of connectors supported on the container, the plurality of connectors arranged to enable separate and isolated flow of services, fluids and utilities, and the plurality of connectors arranged to enable the feed stream gas to flow into the container, a flow of LNG out of the container and connection of the LNG liquefaction plant to the external source of electrical power, the plurality of connectors including:
• a feed gas inlet connector that is configured to enable the feed stream gas to flow into the container;
• a LNG outlet connector that is configured to enable the flow of LNG out of the container;
• a heat transfer fluid inlet port;
• and
• an outlet port enabling the removal of heat energy from the container;
• wherein the main cryogenic heat exchanger (MCHE) includes an inlet to receive the feed stream gas from the feed gas inlet connector, and an outlet through which LNG exits the main cryogenic heat exchanger (MCHE) and is subsequently fed to the LNG outlet connector.
