The MMG model is used to predict the maneuverability of the SWATH ship. The rotating arm motions with the varied drift angles are numerically simulated to predict the hydrodynamic derivatives only associated with the drift angle and angular velocity and the higher order and the coupled hydrodynamic derivatives, resulting in the improvement of the maneuverability of the SWATH ship during the design process. By keeping the third order hydrodynamic derivatives in the maneuverability motion equation, the rotating circle is calculated and compared with the one obtained from the equation without the higher order coupling hydrodynamic derivatives. It reveals the importance of the higher order coupling hydrodynamic derivatives for the prediction of the maneuverability of the SWATH ship. The maneuverability of a SWATH ship is finally predicted.Read More
