ISBRYTENDE FARTOEY

摘要

An icebreaking ship has a hull including a forward part and an aft part and a screw arrangement in the aft part of the ship. The screw arrangement is designed for propulsion of the ship in the forward direction and is turnable substantially in a horizontal plane, whereby the screw arrangement serves for steering the ship. The screw arrangement and the form of the hull of the ship are dimensioned and designed for allowing the ship to move in the aft direction in heavy ice conditions.
