Time-frequency analysis of acceleration data from ship-ice interaction events [PDF]
Cold Regions Science and Technology, 2018 Abstract During operations with ships in ice-infested waters, vibrations of the hull occur due to ship-ice interaction. The acting ice load and the induced vibrations depend on the ice regime and ice breaking mechanism. Especially crushing of ice against the hull causes high loads against the vessel.

Marine Structures, 2020 Abstract The climate change has made the transit through Arctic area more feasible, which demands reliable methods to evaluate ship performance. Ship performance in ice is a cross-scale problem, where the desired output such as ship speed lies in larger scale while the actual ship-ice interaction happens in smaller scale.

A Numerical Ice Load Prediction Model Based on Ice-Hull Collision Mechanism
Applied Sciences, 2020 A simplified numerical model is introduced to predict ice impact force acting on the ship hull in level ice condition. The model is based on ice-hull collision mechanisms and the essential ice breaking characteristics. The two critical ice failure modes,

Coupled Lattice Boltzmann and Discrete Element Simulations of Ship-Ice Interactions
IOP Conference Series: Materials Science and Engineering, 2023 Abstract Evaluating ice loads acting on ships is essential for the safety of ships navigating in ice-covered seas. In this study, we develop a CFD method to handle ship, ice, and fluid interaction. The lattice Boltzmann method, capable of large-scale calculations, is applied to the simulation of free-surface fluids.
