The invention discloses a bottom-sitting ship, which comprises a ship body internally comprising a middle ballast tank and side ballast tanks arranged on the two sides of the middle ballast tank; the size of the middle ballast tank is larger than that of the side ballast tanks. The self-pressure discharge system comprises a self-pressure discharge pipeline and a first discharge port, the first discharge port is arranged on the ship board, one end of the first discharge port is communicated with the outside of the ship body, and the other end of the first discharge port is communicated with the first end of the self-pressure discharge pipeline; and the second end of the self-pressure load discharging pipeline is communicated with the middle ballast tank. By means of the arrangement, when the bottom-sitting ship needs to sink, ballast water is pumped into the bottom-sitting ship at the maximum ballast efficiency, the self-pressure load discharging system is started, seawater can flow into the middle ballast tank through the self-pressure load discharging pipeline, and the ballast efficiency can be greatly improved. When the bottom-sitting ship needs to float, the self-pressure load discharging system is also opened, ballast water in the middle ballast tank automatically flows out, and the load discharging efficiency of the ship body is improved.

    本发明公开了一种坐底船,该坐底船包括:船体,内部包括中部压载舱以及设置于所述中部压载舱两侧的侧部压载舱;所述中部压载舱的体积大于所述侧部压载舱的体积;自压排载系统,包括自压排载管路和第一排海口,所述第一排海口设置在所述船舷上,所述第一排海口的一端与所述船体的外部连通,另一端与所述自压排载管路的第一端连通;所述自压排载管路的第二端与所述中部压载舱连通。如此设置,当坐底船需要下沉的时候,以最大的压载效率向内部打压载水,开启自压排载系统,海水会通过自压排载管路流入中部压载舱内,能够极大地提升压载效率。在坐底船需要起浮的时候,也打开自压排载系统,中部压载舱内的压载水自动流出,加快了船体排载的效率。
