Abstract: Difficulties are often encountered in a variety of seabed sediments during extraction of spudcan foundations of mobile jack-up rigs. This paper reports results from centrifuge model tests undertaken to provide insight into ...

Abstract: The paper describes a mechanism-based design approach for assessing spudcan penetration in soft nonuniform clay with an interbedded stiff layer. The proposed approach is developed on the basis of the results from a parametric ...

Abstract: Spudcan foundations for offshore mobile drilling rigs are large saucer-shaped foundations that can penetrate several tens of meters into soft sediments. The penetration depth is typically predicted by considering a ...

Abstract: This paper reports the results from a series of model tests undertaken to provide insight into the behavior of torpedo anchors during dynamic installation and pullout in lightly overconsolidated kaolin clay and calcareous ...

Abstract: In practice, natural soils exhibit strain-rate dependency and also soften as they are sheared and remolded. Traditional design approaches, however, have been developed based on idealized rate-independent perfectly plastic ...

Abstract: The paper presents a new mechanism-based two-step approach for assessing spudcan penetration resistance in three-layer stiff-soft-stiff clay sediments. An alternative approach is also proposed, establishing a direct ...

Abstract: This paper explores the interpretation of undrained shear strength and layer boundaries from T-bar penetration resistance profiles in layered soft–stiff and stiff–soft clay sediments. The proposed interpretation framework ...

Abstract: This paper for the first time, to the best of our knowledge, reports 10 case histories of jack-up rig installation in different locations of the Gulf of Mexico consisting of seabed soil stratigraphy with weak surface (soft) ...
