Abstract

PURPOSE: To break an ice board efficiently in a catamaran type Archimedean screw icebreaker by providing an ordinary type screw-propelling device in the rear end of each trunk of the catamaran icebreaker for facilitating the front part of the hull to run on the ice board.
CONSTITUTION: A propelling device consisting of an ordinary type screw 10 and others is provided on the rear end of each trunk of a catamaran type Archimedean screw icebreaker. When an Archimedean screw 3 in bows catches an ice board 13, a hull 1 is propelled forward by propeller screws 10. Consequently, the Archimedean screw 3 is pushed to the ice board 13 and the front part of the hull can run on the ice board 13 easily for breaking the ice board efficiently.
