Abstract: A liquefied natural gas production facility and a method of designing and constructing a liquefied natural gas production facility are described. The facility includes space-apart modules for installation at a production location to form a production train including a major axis and a minor axis, each module including a module base for mounting a plurality of plant equipment associated with a selected function assigned to the module, the module base including a major axis and a minor axis. Heat exchangers are arranged to run parallel to the major axis of the production train to form a heat exchanger bank including a major axis and a minor axis, where the major axis of the bank is parallel to the major axis of the train. A subset of the plurality of heat exchangers is arranged on a first level vertically offset from the base of at least one module.
