This paper presents the results of computer simulations of pack ice forces on three candidate offshore systems (which consist of a drill ship, a four legged semi-submersible platform and a six legged semisubmersible platform) using the computer code DECICE, which is a time-domain solver that uses discrete elements to model ice engineering problems. Two force components (in the plane of the waterline) and moments acting on the structure were computed for a range of ice drift velocities, ice coverage and heading angles relative to the ice drift direction. The results of the simulations give reasonable trends of ice forces and moment acting on the structures and the predicted ice flow patterns around the structure are realistic.
