| Summary: | Ship maneuvering experiments in ice are being conducted at the Institute for Ocean Technology (IOT) of the National Research Council of Canada. The aim is to provide a model test database for a subsequent mathematical and numerical modeling of the interaction processes between the ship and ice. The first phase of the experiments was carried out using a 1:21.8 scaled model of the Canadian Icebreaker, Terry Fox. The test program included straight resistance runs and turning circles maneuvers achieved by using a Planar Motion Mechanism (PMM) apparatus. In each experiment tow forces, turning moments, and ship motions were measured. In this paper, preliminary results of the experimental program are presented. The dominant ice-ship interaction processes are identified. The test results show large influence of ship motions and interaction geometry on the measured yaw moments. The geometrical aspect of the interaction processes is described and its influences on ice loads are discussed. Conclusions are made and recommendations for future works are provided.
