Abstract

Flexible structures built in sea ice infested waters require countermeasures against ice-induced vibrations. A design strategy to improve the dynamic ice-structure interaction is proposed, considering the behaviour of sea ice forces. According to the controlled displacements of the structure, the mode shapes are optimized by adjusting the local structural stiffness. The approach and its efficiency are illustrated by a Bohai jacket.
