The invention discloses a wide-body double hull board side double bottom ship based on large openings of inner rib plates in a ballast tank. A board side and a bottom comprise a double-shell shell; rib plates of vertical structures are spaced from one another between an inner shell and an outer shell of the board side. When the distance A of the inner shell (1) and the outer shell (2) is greater than 8 percent of width B, the area of openings which are vertically spaced from one another in the rib plates is 25 percent greater than the sectional area of a three-dimensional structure defined by the inner shell (1), the outer shell (2) and upper and lower adjacent horizontal girders and perpendicular to the length direction. The ship has the advantages that the welding workload and the lightship weight are effectively reduced, the steel utilization rate is improved, the load of liquid cargoes and waves is effectively transferred through arrangement of transverse and vertical stiffeners and the radius size of vertical and transverse connecting arc, the welding area is effectively increased and the stress is reduced by adopting 25-degree snip on end parts of the transverse and vertical stiffeners, and the requirement on structural strength at regions with the large openings can be met through rational arrangement.
