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 ...

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 ...

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).

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 ...

Suction Piles/Caissons

2017
A suction pile is a foundation embedded into the sediment at seafloors through either pushing due to the weight of the pile and its associated mass, or creating a negative pressure inside the suction pile.

Measured Horizontal Capacity of Suction Caissons

Offshore Technology Conference, 2004
Abstract Laboratory tests were conducted to study the behavior of suction caissons when loaded horizontally below the mudline. The experiments were performed using a 4-in. diameter caisson installed to a depth of 32 in. in normally consolidated kaolinite clay.

Soil Reconsolidation Following the Installation of Suction Caissons

Offshore Technology Conference, 2003
Abstract Experiments are being performed with a prototype suction caisson in tanks of soft clay. This paper contains recent test results and numerical simulations showing the reconsolidation behavior of the soil around the installed caisson.

Numerical Analysis of Bearing Capacity of Suction Caisson

Volume 2: Structures, Safety and Reliability, 2008
This paper presents a finite element modeling for determination of bearing capacity of a suction caisson subjected to vertical uplift loading. The approach looks at the uplift capacity of the caisson considering a non-uniform cross sectional area to account for a geometry optimization.

Application of Suction Caisson Foundations in the Gulf of Mexico

Offshore Technology Conference, 1998
Abstract In the last decade, use of suction caissons (suction piles) has increased in offshore arena. Suction caissons have the appearance of inverted buckets with sealed tops and are installed by pumping water out of them.
