Journal of Offshore Mechanics and Arctic Engineering, 2023 AbstractFor ships navigating in ice floe fields, ship–ice–wave interactions may affect ship performance and ice impact forces. This paper presents an approach to evaluate the cross-coupling added mass and hydrodynamic damping between a passing ship and a free-floating small/medium size ice floe based on the boundary element method (BEM). The influences

Ice forces acting on towed ship in level ice with straight drift. Part II: Numerical simulation
International Journal of Naval Architecture and Ocean Engineering, 2018 A numerical method is proposed to simulate level ice interaction with ship in transverse and longitudinal directions in time domain. A novel method is proposed to simulate non-symmetric transverse force in a stochastic way.
