• In coastal region throughout arctic oceans the seabed is frequently scoured or gouged by moving bodies of ice such as icebergs and sea ice keels associated with pressure ridges. Ice scouring may present a severe environmental hazard posed to marine pipelines and other seabed structures. To investigate the ice scour events, both centrifuge model tests and numerical simulations were conducted. Attention was focused on the subscour soil deformation. The centrifuge model tests yielded extensive data which allowed to clarify the scour mechanism and to verify the numerical analysis technique. A finite element model, based on large displacement and plastic formulation, was adopted to analyze the ice scour events. The results from finite element analyses were examined and compared with the experimental data from the geotechnical centrifuge tests.
