APPARATUS FOR CONTROLLING PARAMETRIC ROLL OF SHIP

PURPOSE: A parametric swaying control device of a ship is provided to control the stem angle and rolling of the ship by using the rudder of the ship and to additionally control the rolling by using a pin stabilizer. CONSTITUTION: A parametric swaying control device of a ship comprises a steering unit(4), a rolling measuring unit(15), a fin stabilizer(100), and a control unit(10). The steering unit operates the steering of a rudder(5) installed in the ship. The rolling measuring unit measures the rolling element of the ship. According to the rolling of the ship, the fin stabilizer controls the angle of a fin to control the parametric rolling of the ship. According to a rolling measuring value from the rolling measuring unit, the control unit controls the stem angle and rolling angle of the steering unit.
