Mitigating ice-induced vibration by adding ice-breaking cone

Full scale tests were conducted on a monopod structure before and after an icebreaking cone was added. The effectiveness of mitigating ice induced vibration through adding ice-breaking cone was evaluated based on test data. It was found that significant ice induced vibration can occur on both of vertical and conical structures, but that vertical structures suffer from more intense and harmful steady state vibration. The dynamic ice force and structure response of vertical and conical structure were discussed based on test data. Copyright © 2010 by The International Society of Offshore and Polar Engineers (ISOPE).
