Abstract: Method for processing, treatment and liquefaction of natural gas proximate offshore gas fields with a gas floating production storage and offloading vessel with a primary processing unit, a gas treating unit, and a natural gas compressor. The liquefaction is split between a liquefied natural gas transport vessel moored on a disconnectable turret and the floating production storage and offloading vessel. High pressure liquefied natural gas inlet quality gas from the vessel is sent through conduits to the liquefied natural gas transport vessel(s) then back through the disconnectable turrets to the vessel. A separate nitrogen refrigerant on the transport vessel provides final stage liquefaction while being powered by the transport vessel's propulsion plant. When the transport vessel is full, the transport vessel disconnects from the disconnectable turret, and motors to a transfer terminal located in sheltered water for transfer of liquefied natural gas cargo to a standard trading tanker.
