Abstract: The problem of scouring by icebergs and ridge keels is of concern in the planning and design of seabed installations for the offshore oil industry. Side scan sonar surveys, observations using manned submersibles, evaluation of the geological and geotechnical properties, and mathematical and physical modelling of the scour processes are some of the methods currently used for understanding the problem of iceberg scours. The different postulations of scour mechanics and the results of observations in different geological environments are reviewed in this paper. Iceberg-seabed interactions also induce forces under the keel which create additional stresses on structures buried below the zone of maximum observed scours. This is an area of research to be pursued. A brief review is given on the ongoing DIGS (Dynamics of Iceberg Grounding and Scouring) experiments.
