AbstractThe Institute for Ocean Technology of the National Research Council of Canada has conducted a series of resistance, propulsion and manoeuvring tests on a scale model of the Korean icebreaker Araon attached to a Planar Motion Mechanism (PMM) and in a self-propelled test configuration. Investigation of the Araon’s podded propulsors and their influence on ice-hull load distribution were conducted in open water and level ice, pack ice, ridges and rubble. The tests included straight, zigzagging, and circular runs with control over propeller shaft speed and pod angle in both configurations. Ice loads, model position, pod performance characteristics and ice-hull pressures were monitored during these tests. From these measurements the full-scale icebreaking, manoeuvring, and propulsive capabilities can be predicted and compared with the ship’s actual performance. The tests were used as a study of the hull form’s clearing ability as well as the loading it experiences from encountering ice during different manoeuvres.
