The present paper describes a simulation tool for physical ice management operations. Resistance in level ice or in floes and manoeuvrability in ice are estimated thanks to semi-empirical methods and validated through comparison with model test data. From a target floe size, trajectory of management vessel is calculated in order to protect a structure against drifting ice according to linear, sector and circular management techniques. The tool produces visualization of the operations, with indication of the requested power level and distributions of the resulting floe size.
