Offshore
structures exposed to sea ice can experience different loading conditions.
Dynamics of ice and structure need to be considered during the design phase to
account for velocity dependent loads and ice-induced vibrations. Prediction of
ice load and structural response in non-linear ice-structure interaction
problems is still a challenge and no universal solution to assess them is
available to date. Both numerical and experimental attempts are made to
increase our knowledge on dynamic ice-structure interaction.

The
presentation illustrates the need for a reliable prediction of possible
interaction scenarios, presents ongoing research, and the possibilities to
assess ice loads and dynamic response of offshore structures by model tests.
