Suction Caissons in Intermediate Soils

9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”, 2023
Suction 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, 2023
Abstract 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, 2014
This 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 ...

Use of suction caissons for seawall construction

Ocean Engineering, 2022
With rising sea level and demand for more nearshore infrastructures, the current methods for seawall construction may no longer be sustainable. Alternative seawall construction methods need to be developed. When seawall or other coastal defense systems are constructed on soft marine deposits, suction caissons are feasible to be installed into marine ...

Resistance of Caisson Tip with Internal Bevels for Suction Caissons Penetrating into Clay

International Journal of Geomechanics, 2021
Abstract Suction caissons with internal bevels at the caisson tip can effectively reduce resistance to make them to penetrate into the seabed easily.

Inclined load capacity of suction caissons

International Journal for Numerical and Analytical Methods in Geomechanics, 2003
AbstractA simplified method of analysis for estimating lateral load capacity of suction caisson anchors based on an upper bound plasticity formulation is presented. The simplification restricts the analysis to caissons in uniform and linearly varying undrained strength profiles; nevertheless, its computational efficiency permits quick evaluation of a ...
