The invention provides a side thrust grille design method, a side thrust grille installation method, a side thrust barrel and a ship. The side thrust grille design method comprises the following steps that the three-dimensional structure of a side thrust cylinder, the three-dimensional surface type of a hull outer plate corresponding to the side thrust cylinder and design parameters of a side thrust grille are obtained; according to the design parameters of the side-pushing grating, obtaining a side-pushing grating projection on a predetermined plane; rotating the projection of the side pushing grating by a preset angle on a preset plane; drawing a plurality of side-pushing grating part sections along each side-pushing grating part projection side line; the sections of the plurality of side thrust grille parts intersect with the three-dimensional surface type of the hull outer plate to obtain the surface type of the outer wall surface of the side thrust grille; the sections of the plurality of side-pushing grating parts are intersected with the three-dimensional surface type of the side-pushing barrel to obtain a side-pushing grating supporting surface type; on the section of each side pushing grating part, the first intersecting line is moved by a preset distance, and the surface type of the inner wall surface of the side pushing grating is obtained; and obtaining the three-dimensional structure of the side-pushing grid and the three-dimensional structure of the side-pushing grid part.
