Advances in Offshore Geotechnics

Monday, 1 May
600
Technical / Poster Session
Significant advances are being made in offshore geotechnics, in the areas of foundation design, installation and stability during service. These advances are driven by a combination of research and operational experience. The session includes studies of well conductors, seismic stability of mudmats, analysis of wave-soil-structure interaction, modeling of spudcan and pile installation and an update of a normalized soil parameter procedure for estimation of undrained shear strength. This session will showcase these advances and provide an opportunity to re-evaluate best practices in offshore geotechnics.
