Abstract:

An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms has been enhanced recently by numerical simulations utilizing the discrete element method. The discrete element model CICE has been validated for ice ride-up mechanisms on artificial beaches. CICE simulations of ice ride-up on two beach configurations were compared with large-scale physical model tests conducted in the Esso Test Basin. The model simulations are capable of predicting ice failure mechanisms, extent of ride-up, and ice sheet waterline buckling instabilities. Parametric studies of ice ride-up and pile-up on artificial islands have been conducted by CICE to aid the designer in evaluating slope angles and ice protection schemes. Ice ride-up studies are presented for an artificial island with a stepped-sloped cross-section for ride-up protection.
