Abstract
Offshore structures are prone to ice-induced vibrations when they are subjected to the action of drifting level ice. These vibrations may cause liquefaction of the seabed. They may also cause fatigue problems and have adverse effects on the working conditions on an offshore structure. This paper describes first a mechanism in ice-structural interaction, which is responsible for the generation of steady-state vibrations. Second, parametric studies are carried out with a numerical model. The results show that steady-state vibrations can be prevented by using solutions which provide a sufficient amount of structural damping.
