The invention provides a design method and system for drain holes in the periphery of a ship ballast tank suction port. Comprising the following steps: S1, determining design information of a suction port on a ship structure, acquiring an arrangement position of the suction port according to the design information of the suction port, and determining design parameters of a ballast pump corresponding to the suction port; s2, a multi-layer structure on the peripheral side of the suction port is determined according to the hull structure; s3, according to the arrangement positions of the suction ports and the design parameters of the ballast pump, sequentially obtaining numerical models of ballast water drainage of the multi-layer structure; s4, analysis is carried out based on the numerical model, and the areas of drain holes needing to be arranged of the multi-layer structure are sequentially determined; s5, determining a drain hole arrangement principle; and S6, the drain holes are arranged according to the areas of the multiple drain holes and the drain hole arrangement principle. The specification and size of the drain hole can be determined according to the position and size of the suction port, the arrangement position of the drain hole is obtained, and on the premise that the area of the drain hole meets the requirement, the strength of the ship structure is guaranteed, and the ship safety is improved.
