Analysis of suction caisson anchors in sand connected to floating offshore wind turbines via catenary mooring using a three-dimensional displacement method

International Journal of Geotechnical Engineering
There has been little analytical study to clarify the relationships among the mooring chain configuration, the caisson padeye depth, the tensile load induced at the caisson padeye, and the horizontal load at the spar fairlead of a floating offshore wind ...

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.

Extraction behavior of a modified suction caisson by reversely pumping water in layered soils

Marine Georesources & Geotechnology
The suction caisson can be extracted for reuse by reversely pumping water after the decommissioning of offshore structures. Model tests were conducted to explore the modified suction caisson (MSC) extraction behavior by reversely pumping water.

A modified suction caisson penetrating in clay simulated by large deformation method

Marine Georesources & Geotechnology
Suction foundations, which are widely used in marine engineering for their cost-effectiveness and reusability, have evolved into modified suction caissons (MSCs) incorporating an internal caisson (IC) and an external skirt (ES).

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.

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.
