Resistance of Caisson Tip with Internal Bevels for Suction Caissons Penetrating into Clay
International Journal of Geomechanics, 2021Abstract Suction caissons with internal bevels at the caisson tip can effectively reduce resistance to make them to penetrate into the seabed easily.

Installation of Suction Caissons in Sand with Silt Layers
Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2007Suction caissons are increasingly being used for offshore anchors because of their ease of installation. However, for soil profiles that have sand overlain by layers of silt, there are reasons to believe that it may not be possible to install suction caissons.

Genetic-based modeling of uplift capacity of suction caissons
Expert Systems With Applications, 2011In this study, classical tree-based genetic programming (TGP) and its recent variants, namely linear genetic programming (LGP) and gene expression programming (GEP) are utilized to develop new prediction equations for the uplift capacity of suction caissons. The uplift capacity is formulated in terms of several inflecting variables.

Finite element modeling of the tensile capacity of suction caissons in cohesionless soil
Applied Ocean Research, 2019 When suction caissons are used as foundations for jacket structures, the caissons are exposed to significantvertical loads. If the self-weight of the structure is relatively low, a large horizontal load may lead to tension onthe foundation on the ...

Suction Caissons in Intermediate Soils
9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”, 2023Suction caisson supported jackets have been used on several recent offshore wind farm projects in Europe including Aberdeen Bay, Borkum Riffgrund 2 and Seagreen. Suction caissons are particularly sensitive to soil conditions, including 'intermediate' soils such as partially drained sands, silts, and heavily interbedded sands and clays.

Decommissioning Analyses for Suction Caisson Foundations
Volume 9: Offshore Geotechnics; Petroleum Technology, 2023Abstract Suction caisson foundations are an economic alternative to piled foundations to support offshore jackets, especially in situations where there is shallow bedrock. Over the last few years significant advances in the design of suction caissons have developed, leading to a strong increase in installed suction caissons, particularly

Extraction of suction caissons in sand
Géotechnique, 2014This technical note examines the suction caisson extraction mechanism under steady seepage conditions using a series of centrifuge tests supported by finite-element predictions of these tests. An approximate methodology for prediction of the extraction resistance is subsequently proposed, which is shown to provide a simple means for estimation of ...

An Experimental Investigation Into the Pull-Out Capacity of Suction Caissons in Sand
, 2011 The pull-out performance of conventional suction caissons (with upright walls) has been previously investigated by a number of researchers. However, less attention has been formerly paid to tapered suction caissons.
