Abstract of the Disclosure The method and the means for removing ice from a ship's channel or from around the ship, to ease its navigation. The invention is characterized in that the propeller stream is used for removing the ice by turning the propeller stream up to the surface where the ice is. The removing influence of the stream can be further strenghtened by diverting it also to the sides. Turning up the stream can be done for instance by mixing air into the propeller stream. Mechanical foils (8), for instance tilted ploughing rudders (9,10), can be used for turning the stream up and to the sides. The same air blowing means can be used also for other applications, as loading the payload, or for biological aeration of water.
