Aspects of the present disclosure relate to at-shore liquefaction of natural gas. 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. Numerous additional exemplary aspects of the apparatus and related kits, methods, and systems are disclosed.
