摘要

A multiple movement control apparatus of a ship for screw vibratory force reduction is provided to reduce vibratory force by a marine propeller. A multiple movement control apparatus of a ship for screw vibratory force reduction comprises a primary additive(10) which is positioned within 2 station to 6 station in the longitudinal direction of the ship and within the propeller shaft center to the bottom in the height direction of the ship, and a secondary additive(20) which is positioned within 0.5 station to 2 station in the longitudinal direction of the ship and within the propeller shaft center to the bottom in the height direction of the ship.
