601: Seabed Scour and Buried-Pipeline Deformation due to Ice Ridges

The objective is to study factors affecting soil and pipeline deformation below scouring ice ridges in the Arctic environment. The study will provide:

1. detailed characterization of moving ice-ridge morphology on the basis of available observations and measurement reports,

2. response simulations of ice-ridge-soil-pipeline systems by means of computational-fluid-dynamics representations and finite-element models that capture flow and deformation in porous media, and

3. development of recommendations regarding the minimum required burial depth for pipeline protection from scouring ice ridges.
