Abstract

Moving ice features impose significant challenges on engineering aspects of offshore oil and gas field development in the Arctic and sub-Arctic regions, particularly related to their interaction through the seabed with submarine installations such as pipelines. This paper compares continuum finite element modelling of ice keel-seabed interaction against physical model data and evaluates the current state-of-the-art. It identifies areas requiring further research and development, and evaluate potential limits on ice gouging in soft to stiff clays.
