... of the ice forces, which in turn depends on managed ice field characteristics (ice concentration, floe thickness, floe size, ice drift speed and direction and inclusion of brash ice and small ice pieces) and the DP system characteristics (DP gain set-ups, control algorithms etc.). Physical model testing...

... Abstract The thickened width of floating ice roads has tended to be a practical consideration rather than a design aspect. Standard methods of calculating the required thickness of ice roads consider the road to be of infinite length and width. In this paper we outline calculations...

...-Arctic. Important components of a ridge creating ice loads are the consolidated layer at the surface (which is considered as solid ice) and the ridge keel below consisting of ice rubble, but much thicker. The load due to the consolidated layer is usually derived as if it is thick level ice. On a cone...
