... depths and pipe–soil interaction rates. A series of centrifuge tests were completed using a scaled model of a 0.324 m diameter pipe in dense silica sand with a viscous pore fluid. The model pipe was pushed into the model seabed at a 60° penetration angle, at various penetration rates and water depths...

...Introduction Abstract This paper is a companion paper to OTC 28671, titled "Experience with Interface Shear Box Testing for Axial Pipe-Soil Interaction Assessment on Soft Clay", and presents a similar range of experience and best practice recommendations for geotechnical laboratory testing...

... Abstract The paper reviews recent advances in the understanding of pipe-soil interaction, and provides a updated knowledge on best practices for on-bottom pipeline design. Since the late 1990s, major programs of research work have been undertaken to develop appropriate models for pipe-soil...

... geotechnical characterization of shallow seabed conditions along flowline routes and (ii) techniques to assess pipe-soil interaction parameters for input to pipeline structural modeling. Recent research into pipe-soil interaction measurement tools and analysis techniques has resulted in rapid advancements...

... and large bending moments on the pipeline. A fully integrated nonlinear dynamic analysis of pipeline-slope response under earthquake loading is impractical due to the spatial extent of the model and complications of pipe-soil interaction. The objective of this paper is to present a numerical model...

... Abstract The force mobilized through the interaction between a pipeline and the seabed is a key to the design of pipelines. Fugro Smartpipe® is a site investigation tool that is designed to measure pipe-soil interaction forces in-situ, at the seabed and at close to full-scale. The tool has...

... Abstract This paper summarizes key areas of research and development undertaken by the SAFEBUCK Joint Industry Project (JIP), including the development of engineering models and the testing of pipe-soil interaction, fatigue and local buckling. The SAFEBUCK Joint Industry Project set out...

... over time and involves a range of velocity, repeated loading, reversals in direction of movement and variations in vertical pipe load. Axial pipe-soil interaction was initially considered relatively simple and attention was focused on lateral resistance. However, what appeared simple, particularly...

... Abstract This paper outlines recent research into axial pipe-soil interaction from the geotechnical elements of the SAFEBUCK Joint Industry Project. The operational axial pipe-soil friction strongly influences the initiation and cyclic development of lateral buckles, and also controls...

... areas of the Santos and Campos Basins, offshore Brazil, where soft clay is predominant. This has motivated the development of an extensive experimental test program for pipe-soil interaction, aimed at increasing the design reliability of subsea pipelines with lateral buckling. The model presented...

... Abstract This paper addresses the influence of pipe-soil interaction on the design of pipelines susceptible to lateral buckling and pipeline-walking. The pipe-soil response is the largest uncertainty in the design of such systems, and has a significant influence on the structural limit states...

... measurements will complement and enhance the results from existing methods. For unburied high temperature, high pressure pipeline systems, correctly predicting axial " walking?? and controlling lateral buckling is extremely sensitive to the selection of the pipe-soil interaction parameters. Very soft clay...

...., fax 01-972-952-9435. Abstract This paper addresses lateral pipe-soil interaction behaviour at the large displacements that occur with lateral buckling of a pipeline. Force-displacement response models were developed by the SAFBUCK JIP to replace the use of Coulomb friction approximations, which...

...), a model has been developed which describes the load-displacement relationship of the pipe. The pipe-soil interaction model can also be used for soils exhibiting non-associated material behaviour (sand), but the degree to which the curved failure surfaces and the Cam-clay analogy are still applicable has...
