SHIP FOR MOVING IN ICE SEA AND OPEN SEA

摘要

PURPOSE: A ship moving the frozen sea and unfrozen sea is provided to improve the ice-braking power using the inertia according to the weight of the water filled with a tank through the installation of a trim control tank. CONSTITUTION: A ship moving the frozen sea and unfrozen sea comprise a trim control tank, a first hull linear portion(D1H) and a second hull linear portion(D2H). The trim control tank flows in the water corresponding to the frozen sea and forms the frozen sea draft. The trim control tank forms an unfrozen sea draft by discharging the water corresponding to the unfrozen sea. The first hull linear portion displays the ice-braking performance at the location in which the frozen sea ice draft meets the hull. The first hull linear portion is formed into a spoon-shape. The second hull linear portion is formed into a streamline-shape comparing to the first hull linear portion.
