This floating liquefied-gas production facility (1) is equipped with: a gas turbine unit (20); a liquefaction facility (90) that has a primary refrigeration compressor (40) driven by the gas turbine unit (20), and cools natural gas; a drum-circulation-type exhaust heat recovery boiler (30) that recovers the energy of exhaust heat from the gas turbine unit (20) as steam; a component separation system (85) that uses the steam generated by the drum-circulation-type exhaust heat recovery boiler (30) as a heat source to separate components in natural gas obtained from the ocean floor, and sends said components to the liquefaction facility (90); and a fuel gas supply device (100) that compresses end-flash gas and/or boil-off gas, and supplies said compressed gas to the gas turbine unit (20) as fuel.
