ABSTRACT:
An icebreaking ship is equipped, on the forward quarter of the hull, on both side flanks in the vicinity of the water line, with first and second icebreaking structures, with the second icebreaking structure located at some distance behind the first. Between the two icebreaking structures is a recessed area, which has a curve profile which approximately matches the radius of curvature of the inside turning circle of the ship at the crown or zenithal line of the turning circle. The second icebreaking structure is designed so that it does not exceed the width of the hull and the recessed hull wall area between the icebreaking structures is designed as a waistline-like indentation in the hull.
