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 ...

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.

Genetic-based modeling of uplift capacity of suction caissons

Expert Systems with Applications, 2011
In 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.

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.

Installation of Suction Caissons in Sand with Silt Layers

Journal of Geotechnical and Geoenvironmental Engineering, 2007
Suction caissons are increasingly being used for offshore anchors because of their ease of installation. However, for soil profiles that have sand overlain by layers of silt, there are reasons to believe that it may not be possible to install suction caissons.
