Zusammenfassung:	[Problem] To provide a natural gas liquefaction device that can be easily maintained and that has a compact configuration. [Solution] A natural gas liquefaction device to liquefy natural gas comprises: equipment installation areas A1 to A5 in which an equipment group comprising a plurality of devices is installed; and an access path 4 for maintenance that is provided along the equipment installation areas A1 to A5 and into which only a maintenance crane, which is a mobile crane of a size that is not greater than a preset maximum lifting load, can enter and operate. When a maintenance crane 40 has been disposed along the boundary of the equipment installation area A1 to A5 including the edges of the access path 4 for maintenance, a device, from the plurality of devices contained in the equipment group, on which maintenance is to be performed using a crane is disposed in an area within the work radius of the maintenance crane 40 decided upon according to the load to be lifted.
