Predicting the resistance profile of a spudcan penetrating sand overlying clay
Assessment of the risk of punch-through failure of spudcan foundations on sand overlying clay requires prediction of the full penetration resistance profile, from touchdown and through punch-throughExpand

Bearing capacity on sand overlying clay soils: experimental and finite-element investigation of potential punch-through failure
When a jack-up spudcan foundation is installed on seabeds consisting of a sand layer overlying soft clay, the potential for ‘punch-through' failure exists. This happens as a result of an abruptExpand

Revealing the bearing capacity mechanisms of a penetrating spudcan through sand overlying clay
The safe and economic use of mobile jack-up structures is still hindered by limited understanding of the installation of their large conical ‘spudcan’ footings in layered sand over clay sites. ThisExpand

Bearing capacity on sand overlying clay soils: a simplified conceptual model
The derivation of a new conceptual model for predicting the peak penetration resistance of circular footings installed vertically into sand overlying soft clay is presented in this paper. Based onExpand

Predicting peak resistance of spudcan penetrating sand overlying clay
AbstractAccurately predicting peak penetration resistance qpeak during spudcan installation into sand overlying clay is crucial to an offshore mobile jack-up industry still suffering regularExpand

Assessing the punch-through hazard of a spudcan on sand overlying clay
A complete analytical method to describe the full load-penetration resistance profile of a mobile jack-up spudcan footing penetrating a sand over clay stratigraphy is described. It is based on bothExpand

Investigating six-degree-of-freedom loading of shallow foundations on sand
Laboratory studies of the response of shallow foundations have previously considered only planar loading. This paper describes experimental work carried out using a loading device that appliesExpand

Experimental observations of the penetration of spudcan footings in silt
Mobile drilling platforms perform the majority of the world's drilling in water depths up to approximately 120 m. The installation of their large, inverted, conical spudcan footings into fine-grain...

Set Up and Resulting Punch-Through Risk of Jack-Up Spudcans during Installation
AbstractThis paper addresses a three-dimensional consolidation problem through experimentation in a geotechnical centrifuge. During a discontinuous footing installation, which is typical for mobileExpand
