CAISSON: A Suction Pile Design Tool
Volume 6: Polar and Arctic Sciences and Technology; Offshore Geotechnics; Petroleum Technology Symposium, 2013 The two main suction pile design methods that are generally applied and accepted within the industry are 3D Finite Element analysis and limit equilibrium. The limit equilibrium method involves assuming a number of failure mechanisms with the mechanism offering the least resistance adopted for design.

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

Modelling the variation of suction pressure during caisson installation in sand using FLAC3D [PDF]
Ships and Offshore Structures, 2017 A suction caisson is an upturned ‘bucket’ of cylindrical shape made from steel. This type of foundation has been very popular in the oil and gas industry and the current trend is to extend its use to offshore wind farms. Seepage conditions play a pivotal

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 ...

Use of suction caissons for seawall construction
Ocean Engineering, 2022With 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, 2021Abstract Suction caissons with internal bevels at the caisson tip can effectively reduce resistance to make them to penetrate into the seabed easily.
