DECICE - a discrete element numerical modeling program - has already been proven as a tool for analyzing structure-ice interaction (Lau 1994a, 1994b, 1999 and Lau et al., 1996, 2000). The objective of this project is to extend the versatility of DECICE so that it includes modeling of the interactions of vessels with pack ice and level ice. This report summarizes exploration of the feasibility and efficiency of using DECICE to numerically model vessel action in ice environments. The unique characteristics of DECICE and their application to this problem are discussed. The development of standardized numerical model methodology and techniques are presented. Numerical tests for two types of ice performance tests are presented; resistance in pack ice and level ice turning circle tests. Results of these tests are compared with published model tests in order to verify the numerical models.
