Increasing maritime traffic, combined with the possible warming of the climate, will affect the demand for icebreaking assistance. Accurately predicting the local demand for assistance without an appropriate simulation tool is hard because of the number of variables that must be considered. This report describes a simulation tool built around a deterministic, ice-breaker movement computer model. The tool is still under development, and has not yet been tested with real data. However, preliminary test results based on selfgenerated input data are promising.
