Abstract: Described herein are apparatuses and systems related to at-shore liquefaction of natural gas. The at-shore water-based apparatuses can include 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 be supported by a plurality of support structures extending through an upper deck of the hull.

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.

Abstract: Described herein are systems related to at-shore liquefaction of natural gas. In some cases, the system for liquefaction of natural gas can include a land-based source of electricity; a land-based source of feed gas; an at-shore water-based apparatus moored to an at-shore location, and a transit bridge extending between the water-based apparatus and land upon which the land-based source of electricity and the land-based source of feed gas are located. The at-shore water-based apparatuses can include 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 transit bridge can support at least one of a first line for transmitting electricity from the land-based source of electricity to the water-based apparatus and a second line for carrying feed gas from the land-based source of feed gas to the water-based apparatus.

Abstract: Described herein are apparatuses and systems related to at-shore liquefaction of natural gas. The at-shore water-based apparatuses can include a hull, an air-cooled electrically-driven refrigeration system (“AER System”), a plurality of liquefied natural gas (“LNG”) storage tanks that are on a lower deck of the hull, and a closed loop ballast system. The closed loop ballast system can include a ballast fluid to assist in stabilizing the water-based apparatus moored to an at-shore location without discharging the ballast fluid to water proximate the at-shore location. Systems including an at-shore water-based apparatus can also include a land-based source of electricity and a land-based source of feed gas.

Abstract: Described herein are methods of manufacturing an at-shore water-based apparatus for liquefaction of natural gas. In some cases, the methods can include determining a weight of an air-cooled electrically driven refrigeration system (“AER System”); locating a ballast medium in a hull where the ballast medium has a simulated weight approximate to the weight of the AER System; determining a deflection of the hull caused by the simulated weight; moving the ballast medium off the hull while attaching the AER System; assembling a plurality of liquefied natural gas (“LNG”) storage tanks in the hull; and coupling the AER System with the LNG storage tanks. The ballast medium can be moved off the hull such that the weight of the ballast medium supported by the hull is reduced in order to maintain the deflection of the hull while the AER System is attached.

One exemplary aspect includes an apparatus comprising: (i) an air-cooled electric refrigeration module (“AER Module”) configured to input electricity and preprocessed feed gas from a source, convert the preprocessed feed gas into a liquefied natural gas (“LNG”), and output the LNG; and (ii) a plurality of LNG storage tanks configured to input the LNG from the AER Module and output the LNG to an LNG transport vessel. According to this aspect, the AER Module may be on an upper deck of a water-based apparatus, and the plurality of LNG tanks may be in a hull of the apparatus.
