Abstract: A three-degree freedom mathematical model of maneuvering motion for an ultra-large type container ship with twin-propeller twin-rudder is established, with turning circle test and zig-zig test simulation results to verify it. By abstracting the ship maneuvering process, the three-dimensional model of ship, helm, propeller and rudder are modeled according to virtual reality technology, and then the ship posture and the dynamic process of ship maneuvering are displayed by the virtual scene and the responsive three-dimensional model. A virtual simulation system for the maneuvering of ultra large twin-propeller twin-rudder ship is established by the MFC framework and the Vega API. The functions including scenes switching, environment switching, maneuvering switching and viewpoint switching are completed in the virtual simulation system. The system also could be used as a platform for simulation verification of ship maneuvering control strategy and optimization of control algorithm.
