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. A probabilistic pipelineburial analysis is incorporated that accounts for the influence of sub-gougesoil displacements. Ice gouge rates and geometry are based on repetitivemapping survey data.
