Abstract

PURPOSE: To reduce ice breaking resistance in case of rectilinear propagation while displaying sufficient turning performance when turning, by mounting projections for breaking ice plates, which are provided with specified conditions, to a stem portion.
CONSTITUTION: A distance LB up to a starting point M of the widest portion of a hull from stem FR in a rectilinear propagation draft WL1, a draft of normal sailing, and height H from the rectilinear propagation draft WL1 of projections are each made to be LB=0.27LppW0.34Lpp and H≤1.19h (Where, Lpp=the length of a ship and h=mean ice thickness). The projected width W of the projections is made to be W/Lpp=Lpp8R (Where, R=the radius of the minimum gyration of the ship) or W>Lpp=0.0125W0.025. The projections 2, 2 are mounted to a broadside of a stem portion so that the ship widest portion in a turning draft of the stem portion be included. Consequently, ice is broken by utilizing the stem portion when rectilinear propagation sailing, and ice is broken by the projections mounted to the stem portion by adjusting draft to the turning draft when turning, thus obtaining wide open sea surfaces, then allowing smooth turning.
