The paper deals with impacts of ice masses with ships and offshore installations, considering the higher velocities found under these circumstances. The perspective is the determination of design criteria for local and global pressures. The uncertainties associated with these estimates are addressed, and scale effects in local and global situations are considered with different but inter-related models. Non-simultaneous failure provides the explanation for scale effects in the case of local pressures, based primarily on probabilistic averaging. Global pressures, averaged over the nominal interaction area, also show a decrease with area, related to fractures in the ice. There is a need for better modelling of the physical processes in this area, and the use of probabilistic failure theories is explored.
