Mathematical Modeling of Ice-Hull Interaction for Ship Maneuvering in Ice Simulations

Abstract

A new ice-hull interaction model using the analytical approach with numerical implementation for simulating various ship maneuvers in level ice is presented. Its simple physical detail and short computation time make it very suitable for real-time simulations. In the model, the icebreaking process was numerically simulated in the time domain. Three independent ice force components, the breaking, buoyancy and clearing forces, representing individual processes identified during a typical ice-hull interaction, are calculated separately and summed as the total ice force. The model is benchmarked against measurements from PMM model tests. A preliminary parametric analysis on the channel width and yaw moment due to the ship motions is carried out using the model. The simulation results demonstrate the capability of the model for the real-time simulations.
