Based on a whole ship model and heeling motion characteristics in ship maneuvering motion, a black-box prediction model for ship maneuvering motion in 4 degrees of freedom is established by using support vector machines. A container ship is taken as study object;while 10°/10°, 15°/15°, 20°/20°zigzag tests and 5°, 15°, 35°turning circle maneuvers are simulated. One percent of the simulation data in 15°/15°, 20°/20°zigzag tests and 5°, 15°turning circle maneuvers are used to train the support vectors. The trained support vector machines is used to predict the 10°/10°, 20°/20°zigzag tests and 35°turning circle maneuver. The predicted results are compared with those of simulation tests to demonstrate the good prediction capability and generalization performance of the proposed model.
