... measurements to be a complete and robust characterization of potentially hazardous features. In this paper, we apply algorithms that detect different types of sea ice features: large singular ice keels, hummocky ice, thick brash ice, old or multi-year ice and marine glacial ice (icebergs and ice islands...

... the failure mechanisms associated with gouging ice ridge keels and the conditions under which these keels will continue to gouge without failure. This is important for the design of subsea structures in shallow waters, where ice keels have been observed to scour the sea floor, posing a threat to pipelines...

... Abstract Subsea pipelines located in ice environments need to be protected from potential ice gouging (also known as ice scouring) created when a moving ice keel interacts with the seabed. The integrity and operability of the pipeline can be affected by direct contact between the ice keel...

... Abstract GIS-based software has been developed under the PIRAM (Pipeline Ice RiskAssessment and Mitigation) program for performing pipeline routing and burialanalysis for protection against ice keel gouging. Results are presented for ahypothetical pipeline in the Canadian Beaufort Sea...

..., 1994). Ice keel/seabed reactionforces, however, can be an order of magnitude greater than other pipelineloading events such as anchor dragging and pullover (Kenny et al., 2007a, b;Palmer et al., 1990). From this perspective, for subsea infrastructure such aspipelines and wellheads, positioned above...
