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.

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 ...

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 ...

Performance of suction caissons in sand and clay
Canadian Geotechnical Journal, 2002The use of suction caissons (suction piles) in marine environments has been increasing in the last decade. A suction caisson is a steel pipe with an open bottom and a closed top that is inserted into the ground by pumping water out of it. Pumping creates a differential pressure across the caisson's top that pushes it into place, thus eliminating the ...

Reliability Assessment of Deepwater Suction Caissons
Offshore Technology Conference, 2000Abstract Currently API provides two sets of guidelines for the design of offshore piles in compression. The first is a working stress design approach (WSD), while the second and more recent is a reliability-based approach that uses load and resistance factor design (LRFD).

CAISSON: A Suction Pile Design Tool
Volume 6: Polar and Arctic Sciences and Technology; Offshore Geotechnics; Petroleum Technology Symposium, 2013The 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.

Analysis of Suction Caissons in Soft Clay
2021The cost of establishing any offshore structure is quite expensive. One of the largest expenses in offshore infrastructure is the foundation as environment like wind, wave, and soil or a combination and poses a challenge in most cases. For observation platforms, suction piles offer an unique advantage that it can be reused any number of times by just ...
