Fluid Force Acting on Floating Ice Floes and Their Drifting Velocity

Abstract

Estimating the ice forces acting on offshore structures constructed in cold region, it is very important to evaluate fluid force acting on the ice floes. This force is called environmental force and sea ice drift is also caused by this force. When fluid force is evaluated, the drifting velocity of sea ice floes is able to be estimated. In this paper we carried a series of experiaments with paraffin ice model and found the relationship between environmental condition (for example the verocity of wind or water), and forces acting on the ice floes, and the drifting velocity of them.
