1. A multiple storage tank system comprising:
a plurality of storage tanks in which a cryogenic fluid is stored;
a plurality of discharge lines respectively connected to the plurality of storage tanks to discharge the stored cryogenic fluid or introduce a cryogenic fluid;
a supply line connected to the plurality of discharge lines and a supply target to supply the cryogenic fluid discharged from the plurality of discharge lines to the supply target;
a build-up line branching off at a predetermined position of the supply line to control internal pressure of a first storage tank of the plurality of storage tanks, the build-up line having one end branching off from a first point and the other end connected to the supply line at a second point after a portion of the build-up line passes the cryogenic fluid in the first storage tank;
a gas transfer line connected to the plurality of storage tanks to transfer gas inside the plurality of storage tanks;
a first heat exchanger formed at a position in front of the first point where the build-up line branches off from the supply line; and
a second heat exchanger formed at the second point before the other end of the build-up line is connected to the supply line,
wherein when the internal pressure of the first storage tank is controlled while the cryogenic fluid passes through the build-up line, gas inside the first storage tank is transferred to at least one other storage tank of the plurality of storage tanks through the gas transfer line so that internal pressure of the at least one other storage tank is also controlled.
