ABSTRACT

This paper proposed a numerical method to simulate the ice induced forces acting on the hull and the performance of a dynamic positioned vessel advancing in level ice. The interaction between the ship and the ice was considered by adopting a 2–D discretized model. A polygon based detection technique was applied to determine the contact surfaces. The method was validated by comparison with empirical calculation and ship model test of CCGS Terry Fox. Ship maneuvering was simulated by combining the three degree-of-freedom equations of rigid body motion and the Line-of-Sight guidance system.
