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.

Suction caisson anchors [PDF]

, 2018
Suction caissons are a class of embedment anchor used to secure floating facilities to the seabed. They comprise large diameter cylinders, typically in the range of 3–8 m, open at the bottom and closed at the top, and generally with a length to diameter ratio L/D in the range 3–6.

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.

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.
