This invention discloses a method for cooling and depressurizing a large LNG storage tank after long-term quiescence, relating to the field of LNG storage tank technology. The method includes the following steps: filling detection, valve detection, spray control, pressure display, pipeline control, temperature and pressure detection, and valve closure. Before resuming LNG transport, this invention uses a pre-cooling pipeline and spray device to pre-cool the LNG storage tank, reducing the temperature and pressure of the top gas phase space. In the early stages of spraying, the pressure of the LNG storage tank tends to decrease. When the tank pressure drops to a certain value, the vaporization of the LNG entering the tank causes the pressure to rise. Before the LNG tank pressure begins to rise, a BOG compressor needs to be started to extract BOG gas from the LNG storage tank. At this time, the pressure of the LNG storage tank is low, and the temperature of the top gas is reduced, thereby achieving control of the tank pressure before resuming transport after a long period of quiescence, and reducing the time required to start the BOG compressor and the amount of BOG gas flare.
