Preliminary modeling of ship maneuvering in ice
Recent developments of offshore oil and gas reserves in several countries, together with economic studies to increase transportation through the Arctic, has led to a renewed interest in the maneuverability of vessels in ice. Despite the sizeable volume of work, there is not yet a universally accepte...

The geometrical aspect of the interaction processes is described and its influences on ice loads are discussed. Conclusions are made and recommendations for future works are provided.
