Ice-Navigation and Shafting Strength of Ice-Breaker “Fuji”

Abstract

Icebreaker “Fuji” works for the support of antarctic research action after her completion in 1965. There were propeller-blade damages two times due to heavy ice condition during thirteen years operation.
On the 18th research (1976-1977), two engineers (Authors) were permitted to go on board “Fuji” for studying ice-navigation in Antarctic region. This paper discusses the ice-navigation and studies the strength of propeller-blade and propeller shaft of “Fuji” in ice.
