Summary

 
The paper describes the method for estimating the ice resistance of a ship sailing in small and medium ice floes. The method is based on solving the differential equation of motion for ice floes pushed aside by ship hull. The curves of ice resistance versus width of channel in waters infested with small floes are plotted for an icebreaker and a large-size ship. Also, the relationships of net ice resistance versus ice thickness are obtained for different cases of ship speed and consolidation of medium ice floes. Conclusions are given regarding the operation of large-size ships and icebreakers in waters infested with small floes and the results obtained for these ships are compared.
