A probabilistic burial analysis for protection against iceberg scouring of the seabed is presented for a hypothetical pipeline on the Grand Banks off Canada’s east coast. The analysis procedure combines a probabilistic characterization of the iceberg scour regime with a deterministic analysis of pipeline stress/strain response for a range of iceberg scour widths, depths and iceberg keel/pipeline crown clearances, allowing pipeline burial to be defined using specified stress/strain limits and target reliability levels.
