Increase knowledge, and thereby reduce conservatisms, associated with the design process and related limit states of deepwater pipeline design. The key areas of work are: Undertake structural reliability analysis (SRA) to confirm that the SAFEBUCK Design Guideline methodology ensures that the pipeline failure probabilities are consistent with industry targets;
Collection of data on operating pipelines to generate lessons for future design by sharing the combined knowledge of lessons learned from recent projects;
Formalization of the SAFEBUCK Design Guideline into an Industry Recommended Practice;
Development of a new 'force-resultant plasticity model' to run inside standard software packages, capturing experience from modeling and testing lateral pipe-soil interaction; and
Review of axial friction response, based on recent project-specific tests to improve our understanding and quantify the key uncertainties
Multiple reports and modelling studies have resulted from this JIP under 3 main topics: Design, Lateral Pipe-Soil Interaction, and Axial Pipe-Soil Interaction. The final report is an Industry Recommended Practice and tentatively due December 2014. These reports are confidential to paying members for a period of 1 year from the end of the study or release of the final report, whichever is later.
