Performance of suction caissons in sand and clay

Canadian Geotechnical Journal, 2002
The 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 ...

Effect of Seismic Peak Ground Acceleration on the Performance of Shared Suction Caisson Anchors in Clay for Floating Offshore Wind Turbines

Offshore Technology Conference
This study investigates the effect of seismic loading on the performance of a shared suction caisson anchor for a floating offshore wind turbine (FOWT) array with taut mooring configuration in anormally consolidated clay deposit.

Reliability Assessment of Deepwater Suction Caissons

Offshore Technology Conference, 2000
Abstract 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, 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.

Analysis of Suction Caissons in Soft Clay

2021
The 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 ...

Analysis of Suction Caisson Capacity in Clay

Offshore Technology Conference, 2002
Abstract The paper addresses analysis techniques and design parameters for suction caissons in clay for loading conditions ranging from horizontal to vertical. A three-dimensional upper bound approach is described for caissons undergoing significant horizontal motion or rotation, and the relative accuracy of the ...

Buoyant Tower: Experimental and Numerical Studies on Anti-Rotation Behavior of Suction Caisson Foundation

Offshore Technology Conference
The buoyant tower, or BT, is composed of a hull and a suction caisson foundation (SCF). The hull can be one or a group of cylindrical cells, while the SCF should be a short open-bottomed cylinder welded to the end of the hull, holding it to the seabed.

Motion Behavior of The Suction Caisson Induced by Adjacent Spudcan Penetration in Sand

Journal of Intelligent Geotechnical Engineering and Foundations
Suction caissons are commonly used as foundations for deep-sea offshore wind turbines. However, spudcan penetration from jack-up installation vessels can disturb nearby caissons.
