ることを特徴とする砕氷船。 An icebreaker equipped with an ice-breaking device at the bow includes a cylindrical body disposed along the outer surface of the hull and rotatably supported at both ends, a drive device that rotationally drives the cylindrical body, and an ice-breaking device equipped with the ice-breaking device. The cylindrical body is provided in a spiral along the axial outer circumferential surface of the cylindrical body in order to remove or separate the crushed ice floes staying near the underwater part of the cylindrical body from the vicinity of the hull by the rotational flow caused by the rotational drive of the cylindrical body. An icebreaker characterized by being equipped with a blade.
