The invention provides a drainage structure of a ballast tank, which does not significantly prolong the time for discharging residual ballast water from the ballast tank even if water through holes are reduced compared with the prior art. The four small divided chambers (2-1)-(2-4) included in the transverse small divided chamber row (20W) are in a communication state via three water through holes (25) which are located in the transverse small divided chamber row (20W) and which respectively penetrate the three vertical frame members (17). Furthermore, each of the plurality of small compartments included in each of the four longitudinal small compartment rows (20L) is in a communication state through a plurality of water through holes (25) that penetrate the plurality of floor members (13). The four longitudinal small compartment rows (20L) comprise a plurality of small compartments [(1-1)-(4-1), (1-2)-(4-2), (1-3)-(4-3), (1-4)-(4-4)] arranged in the longitudinal direction (L) of the ship and including one of the four small compartments (2-1)-(2-4) constituting the transverse small compartment row (20W).

    本发明提供与以往相比即使减少通水孔,也不会使从压载舱排出残留压载水的时间显著变长的压载舱的排水结构。横向小划分室列(20W)所包含的四个小划分室(2‑1)~(2‑4)经由位于横向小划分室列(20W)内的分别将三个纵框架件(17)贯通的三个通水孔(25)而处于连通状态。另外,四个纵向小划分室列(20L)分别包含的多个小划分室各自通过分别将多个地板件(13)贯通的多个通水孔(25)而处于连通状态,该四个纵向小划分室列(20L)由包含构成横向小划分室列(20W)的四个小划分室(2‑1)~(2‑4)中的一个小划分室且沿船舶的纵向(L)排列的多个小划分室[(1‑1)~(4‑1)、(1‑2)~(4‑2)、(1‑3)~(4‑3)、(1‑4)~(4‑4)]构成。
