The invention discloses an ocean wave compensation device of a deepwater semisubmersible drilling platform. The device comprises three rigid stand bases which are distributed in an equilateral triangle shape and is arranged on a lower hull of a drilling platform and is exposed out of sea level. The upper surface of the rigid stand base is connected with a hydraulic cylinder through a spherical hinge. The end of the piston rod of the hydraulic cylinder is connected with a bearing pedestal which is arranged on the lower surface of an upper table through a pin roll. The hydraulic cylinders are connected with a hydraulic control system, and each hydraulic cylinder is independently controlled by the hydraulic control system. In addition, the invention provides a control method for the ocean wave compensation device of a deepwater semisubmersible drilling platform. The ocean wave compensation device of a deepwater semisubmersible drilling platform can effectively compensate heaving motion of main decks of an upper platform, and rolling and pitching, so as to ensure constant contact of a drill and a shaft bottom in a deep sea well drilling process.
