Ship fins stabilizer is a kind of anti rolling ship technique that can produce lift with initiative swing of fins at zero forward speed

and the lift can counteract the rolling forces of ocean waves.The servocontrol system of zero speed fin stabilizer is designed and the lift restricted part is added.The simulation of anti rolling effect is researched at the different sea wave condition about significant wave height of 1

2 m

wave direction angle of 90°.And the anti rolling effects are 78.30 % and 56.92 %respectively.It is proved that the designed system can be satisfied with the need of anti rolling ship at zero speed.
