SUT-US OSIG Geotechnical fundamentals of pipe-soil interaction for deepwater subsea pipelines

Geotechnical fundamentals of pipe-soil interaction for deepwater subsea pipelines This half-day course will focus on site investigation and design aspects of pipe-soil interaction (PSI) for deepwater subsea pipelines. Specific topics include in-situ testing and soil sampling methods, laboratory testing to quantify soil parameters for inputs to PSI analysis, analytical methods for estimating static and dynamic pipeline embedment and monotonic and cyclic axial and lateral PSI, an overview of axial walking and lateral buckling mitigation techniques, and case studies from monitoring of operational pipeline data. It is designed for engineers with some experience in seabed geotechnics, as well as project managers and other technical professionals working in the area of subsea pipeline design. SUT-US will offer Certificates for Professional Development Hours (PDH) upon request. Here is the Agenda for the day:

Speakers:

He is currently Chair of the SUT-US Offshore Site Investigations and Geotechnics committee, and serves on other industry committees focused on offshore energy.
	Roneet Das - NGI Roneet Das is a geotechnical engineer and researcher with experience across offshore and onshore energy projects. His work focuses on soil–structure interaction, interface shear behavior, geotechnical instrumentation, and geohazard assessment in terrestrial and marine environments. He has led laboratory testing and interpretive programs supporting offshore developments in the Gulf of Mexico, Brazil, Trinidad and Tobago, Guyana, and Mozambique, contributing to ground models and geotechnical bases of design for foundations, risers, and pipelines. His research applies Bayesian methods to pipe–soil interaction and slope stability. Roneet currently serves as Chair of the SUT Young Professionals Committee.
	Dr. Ed Clukey, Ph. D., P.E., F. ASCE, D. OE (ret.), D. GE (ret.) Mr. Clukey holds a master's and bachelor's degree from Worcester Polytechnic Institute and a doctorate from Cornell University. He is a registered professional engineer in California and Texas, a member of the Society for Underwater Technology, a Fellow in ASCE, and a retired Diplomate in Geotechnical and Ocean Engineering. With nearly 50 years of experience in offshore geotechnical engineering, his career includes roles at BP America, McClelland Engineers, Exxon Production Research, and the U.S. Geological Survey. He has been instrumental in developing suction caisson technology and has chaired API task groups for geotechnical guidelines. Since retiring from BP, he founded GeoMaxEd and has been active in COPRI and the ASCE Geo-Institute. He has lectured at MIT and TAMU and authored 55 technical publications. In 2022, he delivered the fifth McClelland lecture in Austin.
