Abstract: Dynamic ship/ice interactions have been considered for different scenarios of collision using a hydrodynamic model of solid/ice impact. As a result, the dynamic load parameters are expressed as products of their dimensional maximum magnitudes and dimensionless time history factors. The maximum ice load parameters are functions of masses and speed of collision, dynamic crushing properties of ice and geometry of the collided ship and ice. There are recommended design formulae and time history diagrams for many practically important cases of the ship/ice interaction, including ramming in an imprint of previous rams. The results can be used both for ice-induced hull girder bending moment calculations and for stress analysis of local ship structure including appendages.
