Sailing through ice requires modifications to the standard ship form in terms of structural strength and hull lines. For ships that sail through light ice or brash ice channels, assisted where necessary by an icebreaker, the challenge lies in striking a balance between optimizing the hull for open water and ice conditions, bearing in mind the commercial potential of the vessel. This paper shows how the addition of DEM to CFD could contribute in the future to the optimization of hull forms of lighter ice classed ships.
