We propose a mean of efficient fluid transportation using large fluid bag in cargo hold and research the bag tention spcific with rolling by an experiment. Moreover we observe the effect of sloshing control way using fluid bag. The initial tention for the fluid bag is strong under dry condition and the variable tention for fluid bag is weak under dry condition more than under water condition. On the other side, the initial tention is offset by the bouyancy under water condition and the variable tention grow strong owing to the fluid bag motion due to the vessel oscillation. The variable tention grow strong near the fluid natural period. However, it is not so big problem, because the original vessel rolling natural period and fluid natural period is out of resonance. The impact force of the fluid sloshing does not occur under dry condition as the free water surfacs is restricted by the bag. Moreover the impact force becomes smaller than usual fluid transpotation.
