According to the ballast tank capable of reducing the sloshing load and the liquefied gas carrier, the side ballast tank and the double-bottom ballast tank are designed in a separated mode in the ballast tank structure, ballast water is only loaded on the upper ballast tank on the side when a cargo hold is partially loaded, the gravity center of the whole carrier is increased, and the sloshing load in the cargo hold is reduced. The reduction of the sloshing load enables the limitation of the liquid level in the cargo hold to be reduced, and the range of the loadable liquid level is larger, so that the loading flexibility of the cargo hold is improved. In addition to a liquefied gas carrier, a fuel cabin or marine operation equipment adopting a film type containment system, the ballast tank is also suitable for liquid cargo cabins and fuel cabins of all other ships or marine operation equipment, and the oscillation load in the cabins can be effectively reduced, so that the structural reinforcement in the cabins caused by oscillation is reduced, and the structural damage in the cabins caused by oscillation is reduced.

    本发明提供一种降低晃荡载荷的压载舱及液化气船,该压载舱结构把舷侧和双层底压载舱分隔设计,货舱部分装载时压载水仅装载舷侧的上部压载舱,提高了整船的重心,减小了货舱内的晃荡载荷。晃荡载荷的减小使得货舱内液位的限制减少,可装载液位的范围更大,从而提高了货舱装载的灵活性。除了采用薄膜式围护系统的液化气船、燃料舱或海洋作业装备,该压载舱的设计也适用于其他所有船舶或海洋作业装备的液货舱、燃料舱,可以有效地减小舱内晃荡载荷,从而减小晃荡引起的舱内结构加强,减少晃荡导致的舱内结构损坏。
