Abstract: An integrated approach is presented to the study of the interactions, ice-structure and of the hydrodynamics of the ice masses in Polar regions, as far as the offshore oil research is concerned. An implemented macro-element approach has been adopted, able to consider the effects of drift forces, damping coefficients, retardation functions and frequency independent added masses of ice bodies in the nearby of offshore structures. On the basis of an available complete and careful characterization of the mathematical and of the experimental aspects of the problem, a deal of possible interaction and collision phenomena ice mass-structure have been completely characterized, in order to reach the aim of facing and of keeping under control the possible risk situations both during the design and during the operational stages. Some results are depicted and pointed out, in order to achieve a complete view of the adopted techniques.
