由液面による影響はほとんど生じさせない。[Operation] Cargo liquid filling and suction into the upper cargo tank is performed through a free flow pipe that penetrates the horizontal oil-tight partition. Then, in the lower cargo tank, the cargo liquid in the upper cargo tank naturally falls into the lower cargo tank due to gravity, so it is possible to squeeze the lower cargo tank to almost the full capacity. Has little effect.
