MODEL TESTS OF TWIN SCREW ICEBREAKER HULL FORMS IN ICE MODEL BASIN

To develop a hull form with good ice-breaking performance, a series of model tests was carried out in the ice tank of the Hamburgische Schiffbau-Versuchsanstalt at NKK's request. The results of resistance and ramming tests of four typical hull forms are compared and show the benefit of a cylindrical stem which breaks ice more by bending than crushing. Using the best of the four forms, the effect of ice thickness, ice strength, and the hull-ice friction coefficient were examined. Self-propulsion tests were also carried out and full-scale performance was estimated from model test results. The simulated conditions for model tests in ice and their practical limitations are also discussed.
