Abstract: First year ridges or hununock fields will give a design global ice load acting on offshore structures placed in sub-arctic region like the sea of Okhotsk. The global loads are calculated by the sum of consolidated and unconsolidated layers. Although the force from unconsolidated layer is thought to be much smaller than one from consolidated layer, there exists unknown factors in terms of effects of grounding, velocity dependence and interaction with consolidated layer etc. Only unconsolidated rubble were built in ice tank and experimental studies were performed to clarify these points. The study shows that the force increases by grounding of the rubble on sea sediment.
