Abstract: Segmented model testing techniques have been developed for testing icebreaking ship hulls in model ice. The segmentation technique was developed following an analysis of the primary sources of ice resistance and the determination of the contribution of various hull geometric areas to the total measured resistance. The segmentation rationale was applied to the hull of the Canadian icebreaker PIERRE RADISSON. A total of three independently supported bow segments were used in this study program. The segment instrumentation and support system was developed to measure the instantaneous loads acting on each segment and define such loads completely in terms of the magnitude and centre of action on the hull, of the normal ice force as well as the magnitude and direction of action of the frictional ice force component. Preliminary results obtained during the early stages of technique development are discussed. The information which can be obtained by using segmented model testing techniques can be instrumental in the development of improved designs for icebreaking ships and can lead to better understanding of the ice loads exerted on the hull under varying ice conditions.
