Abstract: Various aspects include the component problems corresponding to iceberg drift in open water, iceberg drift in the vicinity of a large offshore structure, wave-induced motions of a berg, and the impact of an iceberg with an offshore structure. For smaller ice masses, the effect of a large structure on the berg's trajectory, as well as the wave-induced motions of a berg, are both important problems. The greatest difficulties in force and motion predictions are due to uncertainties in iceberg configurations and in ice properties, rather than due to the simulation of the physical processes involved.
