An embodiment will be described with reference to the drawings. As shown in FIG. 1, the hull has several tanks 1 and is equipped with a loading pipe 5 and an unloading pipe 6. Each tank 1
A vent pipe 2 is erected on the vent pipe 2, and a discharge breather valve 3 and a suction breather valve 4 are provided at the tip of the vent pipe 2. Further, an inert gas cylinder 7 is provided as a device for replenishing the inert gas in the empty space A1 of the tank, and the inert gas pipe 14 is connected to the safety valve 10 through the primary adjusting valve 8 and the secondary adjusting valve 9. Through the side of the hatch 11 through the tank 1
It is designed to fill the empty space A1. Explaining equipment for loading and unloading, the vapor return pipe 17 can be connected from the vent pipe 2, and piping is provided so as to return to the void A2 of the land tank 15. The inert gas pipe 14 of the hull is connected to the inert gas pipe 13 connected from the land-use inert gas tank 12 so that the tank 1 can be filled with the inert gas. In addition, an inert gas pipe 16 is used to fill the land inert gas tank 12 from the land inert gas tank 12.
Is piped. Further, the inert gas pipe 16 of the land inert gas tank 12 is connected to the discharge side of the land pump 18 of the loading pipe 5 sent from the land tank 15, and the discharge pressure is detected by the discharge pressure gauge 19. A little expensive (about 0.5kg / cm
2 G) The pressure of the inert gas is controlled by the automatic pressure control valve 20 so that several percent of the discharge amount of the cargo liquid is injected. Explaining the pressure setting of onboard equipment, generally, the tank design pressure is 0.245 kg / cm 2 G, negative pressure −0.07 kg / c.
m 2 G, the discharge breather valve 3 at the end of the vent pipe 2 is 0.2
0 kg / cm 2 G, the suction breather valve 2 is set at -0.07kg / cm 2 G. Although the maximum capacity of the inert gas cylinder 7 is 150 kg / cm 2 G, the primary regulator valve 8 reduces the pressure to 150 → 4 kg / cm 2 G, and the secondary regulator valve reduces the pressure to 4 → 0.15 kg / cm 2 G. Safety valve 10 is 0.20k
It is set to g / cm 2 G and is designed to fill the empty space A1 of tank 1.
