Abstract

A discussion is presented of the interface between analysis of resistance to ship motion in broken ice and predicting the needed propulsion power. The interface shared by the two separate phases of analysis in icebreaking ship design is still a little known region. The two phases differ structurally in many ways and their common bond is not easily understood. The state-of- the-art of both types of analyses is summarized. A well-reasoned discussion is presented for recent developments in the relations for resistance and propulsion. Points for needed clarification on each side are emphasized. Efforts were made to relate design power requirements with ice resistance technology. As a step forward in overcoming difficulties, the conce
