| Research Abstract |
Numerical estimation method for ship navigation in a brash ice channel which is filled with small ice pieces is developed. The effects of flow field around the ship hull and the initial ice conditions against the ship resistance are investigated using the estimation method. As a result, it is observed that the effect of the flow field around the hull against the ship resistance is small. The effect of ice arrangements against the ship resistance is not negligible, and is not a simple relationship and depends on the size of ice pieces. The effect of shape ratio of spherical and cubic ice pieces is significant so that the appropriate ratio to represent the real brash ice channel should be investigated.
