RESISTANCE AND PROPULSIVE PERFORMANCE TRIALS OF THE MV TERRY FOX AND MV IKALUK IN LEVEL ICE

It has always been recognised that the key to a full understanding of icebreaker powering performance is an accurate knowledge of its constituent parts; ship resistance, propulsor performance and the hydrodynamic interaction between the two. A set of full-scale resistance and propulsive performance tests were carried out to obtain more information on these aspects. Two vessels, the MV TERRY FOX and the MV IKALUK, were selected for the trials. The ships are CASPPR Arctic Class IV icebreakers, with geared-diesel propulsion, the former vessel having twin controllable-pitch propellers, and the latter having twin cp propellers operating in nozzles. Three days of dedicated tests were conducted in Herschel Basin, Yukon. The results of this study included the following: - Vessel resistance in level ice over a range of speeds - Self-propulsion power and thrust over a range of speeds, and - Thrust deduction in level ice and open water of the two systems. The data from these tests can be used to validate or improve the techniques used for predicting icebreaker powering performance from model tests, and empirical or analytical models.
