Abstract: This paper deals with a new formulation of a mathematical model for the prediction of global ice loads due to Impacts of multi-year ice floes on a circular offshore structure during summer loading events. A statistical ice load model, using the concept of zones first developed by Kry (1978), has been modified to take into account a limited penetration of the floe by the structure ("limit momentum"). The model also includes the effect of several parameters on the effective ice pressure such as the ice thickness, the local contact, flexural failure and the general state of the ice floes (temperature, type of ice, quality, etc. .. ). The limitations and sensitivity of the model to the major parameters affecting the effective ice pressure are also discussed
