(54) Title: A CONTAINERISED LNG LIQUEFACTION UNIT AND ASSOCIATED METHOD OF PRODUCING LNG (57) : An LNG production plant (100) is constructed from a plurality of containerised LNG liquefaction units (10). Each containerised LNG liquefaction unit (10) can produce a predetermined quantity of LNG. For example, up to 0.3MPTA. A manifold system (106) enables connection between the plurality of containerised LNG liquefaction units (10), and at least a feed stream of natural gas (110), a source of electrical power, and an LNG storage facility (92). The production capacity of the (100) is incrementally changed by connecting or disconnecting containerised LNG liquefaction units 10 to or from the plant (100) via the manifold system (106). Each unit (10) contains its own liquefaction plant ( 12) having a closed loop SMR circuit. Refrigerant within the SMR circuit is circulated solely by pressure differential generated by refrigerant compressors in the liquefaction plant (12).
