WP3 - Fixed Structures in Ice
To develop the analytical and numerical models needed by the industry to predict the action from ice (first- and multi-year, level ice and ridges) on fixed single and multi leg structures, and to further to develop innovative vibration mitigation measures.
The following gaps need to be addressed in order to reach the above goals: 1) There is presently no clear understanding of how to address ice-structure interaction in many practically relevant situations. To predict ice loads with a desired accuracy, models have to be developed that account for the effects of ice-structure interaction for the predicted failure mechanisms in ice; 2) Represent multi-year ridges and ice in model-scale with respect to size, shape and mechanical properties; 3) There is presently no clear understanding of how to address ice failure against a vibrating structure; in particular, the synchronization of ice failure is not clear.
