Abstract: The Arctic is undergoing profound and rapid change. Diminishing ice in the Arctic will lead to significant changes in the region’s activity level as sea routes begin to open and ice conditions become less restrictive. The U.S. Navy may be asked to operate in waters with up to 40% ice cover. This work addresses Navy Arctic Roadmap action items to understand the capability, limitations, and operational considerations for successful and safe operation of naval surface vessels in the presence of ice. Current ice impact models were developed for impact scenarios and hull forms more appropriate for Polar Class ships rather than naval hull forms. The primary unknowns needed to assess operational risks are the magnitude of the pressures that a surface vessel may experience in the case of an ice impact and the structural response to those impact pressures. For this work, we are solely interested in estimating the location and pressures of ice impacts on combatant hull forms. We present an alternative approach that uses the DEM approach to modeling the ice impact problem.
