... generally relates to the lay process and the resulting influence on the local soil strength and pipe embedment, and can also arise from in situ geotechnical heterogeneity. Epistemic (global) uncertainty relates to potential systematic errors in the assessment of soil strength and the average influence...

... approach is to define the operative soil strength, based on reconsolidation of the remoulded soil beneath the weight of the empty pipe during the intervening period between laying and flooding. This approach is based on pipeline embedment data from the field, which has demonstrated that soil around...

... pipelines governs several aspects of pipeline design and lay route architecture. The observed as-laid embedment in soft soils is greater than would be predicted based on the static penetration resistance of the seabed using the in situ soil strength. Empirical dynamic embedment factors are used to scale...
