Abstract

Ships strengthened for navigation in ice encounter level ice, ice ridge and broken ice fields. Thus, the ship resistance in ice is a very critical concern to the designers of ice-going vessels. The objective of this study is to understand the physical aspects of ship performance in ice and to investigate the characteristics of the ship resistance in broken ice channels. In particular, this study identifies the ship resistance in ice associated with the broken ice channel width and the size of broken ice pieces. Model testings of towed-resistance condition in broken ice channels with three ship speeds were conducted in KRISO ice model basin. The influence of the ship resistance characteristics in broken ice channels for channel width and size of broken ice pieces was analyzed.
