A process and apparatus for exploitation and liquefaction of natural gas in offshore stranded gas reserves. Two ordinary nautical vessels are used to produce, store and unload LPG and LNG. Typical front end processing is performed on the first vessel. The treated inlet gas is transported to the second vessel where the stream goes through liquefaction and storage until it is offloaded to a transport vessel for shipment. The liquefaction process utilizes two refrigerant cycles that utilize two expanded refrigerants, at least one of which is circulated in a gas phase refrigeration cycle. The refrigerants and the inlet gas stream are transported between the two vessels by the use of piping. Electricity can be generated to provide power for the compression sections of the refrigeration cycles. Turbines, engines, or boilers from the vessels can be used for generating electricity since they are no longer needed for locomotion purposes.
