The invention relates to a large floating liquefied natural gas production, storage and unloading device which comprises a ship and FLNG upper facilities arranged on a deck of the ship. The ship is sequentially provided with a fore peak tank, an inner rotary tower single-point bin, an LNG bin, an LPG bin, a gas condensate bin, an oily water bin, a fresh water bin, a diesel oil bin and an after peak tank from a ship bow to a stern. The FLNG upper facilities include a mooring device, a torch tower, an underwater production system control module, a preprocessing module, an LPG recycling module, a propane precooling module, a fuel gas compression module, an LNG output module, a liquefying and refrigerating module, a reservation module, a power station module, an electric room module, an unloading area, a living building and an LPG and gas condensate stern conveying device, wherein the mooring device and the torch tower are distributed on the ship bow, and the underwater production system control module, the preprocessing module, the LPG recycling module, the propane precooling module, the fuel gas compression module, the LNG output module, the liquefying and refrigerating module, the reservation module, the power station module, the electric room module, the unloading area, the living building and the LPG and gas condensate stern conveying device are distributed from the ship bow to the stern in a modular mode. The service life of the device can be 20 years in an in-water mode, the device can bear limiting typhoon and sea conditions with the recurrence interval of ten thousand years, and the device can be widely used for floating production, processing, liquefying, storage and output of natural gas in deep and high seas.
