A boundary element method for the prediction of hydrodynamic ship-ice-wave interactions in regular waves
For ships navigating in ice floe fields, ship-ice-wave interactions may affect ship performance and ice impact forces. This is because the added mass and hydrodynamic damping may influence hydromechanics and associated ship-ice interactions. This paper presents an approach to evaluate the cross-coup...
