This thesis provides a hybrid, numerical and semi-empirical model that predicts ship-ice interaction in level ice. In addition, the model is integrated into an existing software solution, allowing for the simulation of ice management operations and vessel control in sea ice environments. The software implementation numerically solves for contact surfaces between the ship and ice in the time domain and utilizes semi-empirical formulas to estimate the ice forces generated in the interaction. A new method that does not remove rubble ice from the simulation is proposed. The addition of broken ice floes and increased ice shape complexity is facilitated by applying polygon partitioning and simplification algorithms to allow for a an adjustable trade-off between accuracy and performance. The software solution is validated using the data from model-scale tests and-full scale trials. Finally, recommendations for future work to improve upon the proposed model are provided. ...
