Mitigation of Ice-induced Vibrations By Adding Cones

The dynamic ice force and structure response of vertical and conical structures are discussed based on field measurements in Bohai Bay. It is found that significant ice-induced vibrations can occur on both kinds of structures. Adding a cone can avoid a more intense and harmful steady-state vibration. Full-scale tests have been conducted on a monopod structure before and after adding an ice-breaking cone. The effectiveness of mitigating ice-induced vibrations through adding an ice-breaking cone is evaluated based on test data.
