Abstract

Described herein are apparatuses and systems related to at-shore liquefaction of natural gas. The systems can include land-based facilities connected to a source of electricity and feed gas, an at-shore water-based apparatus comprising a hull, an air-cooled electrically-driven refrigeration system (“AER System”), and a plurality of liquefied natural gas (“LNG”) storage tanks that are on a lower deck of the hull. The AER System can comprise one or more refrigeration trains, where each refrigeration train of the one or more refrigeration trains can include a portion of electrically-driven compressors and a portion of air coolers that at least or only partially cover the one or more refrigeration trains.
