Numerical modelling of sea ice is a useful tool in predicting ice rubble formation around offshore and coastal structures. Such models can capably predict rubble height and extent, allowing engineers to pinpoint “problem” scenarios for structures where ice interaction, and its potential for extensive damage, is a concern. This paper describes numerical simulations that were conducted to examine floating ice interaction with a structure located in the Caspian Sea and its planned surrounding protective rubble mounds. Spatial and temporal distributions of ice rubble pile-up height and depth, as well as forces on the mounds, were determined. The numerical model examined a number of different rock mound configurations, the influence of the direction of ice movement and ice sheet thickness. The results are compared with reported pile-up heights, collected from the field site. NRC publication: Yes
