Wave‐Induced Slides in South Pass Block 70, Mississippi Delta
Publication: Journal of Geotechnical Engineering
Volume 109, Issue 4
Abstract
Failure of a major offshore platform caused by a seafloor slide and hurricane wave forces is described. Data on the soils and waves are combined with limit equilibrium, finite element and layered continuum analytical models to determine soil movements and forces. Estimates are made of the ultimate strength of the platform foundation. Comparison of force and resistance characterizations indicates good agreement. Ultimate strength design methods are suggested to supplement present elastic methods in design of slide‐resistant platforms.
