Suction Caisson Installation – Ground Risk Mitigation Planning
9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”, 2023The design of suction caissons for offshore wind farms (OWF) is an iterative process. The final foundation geometry is determined through an iterative process considering the in-place design and the ability to install the caissons to their target penetrations. Small variations in soil conditions and layering affects the installation process.

Tapering Effects on the Installation of Suction Caissons in Clay
Volume 2: Structures, Safety and Reliability, 2008This paper reports results from an investigation on the tapering effects on the installation and pull-out performance of suction caissons. A numerical finite element approach has been used for the study. The finite element models have first been calibrated/verified against several available experimental data for the installation of the upright suction ...

Installation of Suction Caissons in Dense Sand and the Influence of Silt and Cemented Layers [PDF]
, 2005 Suction caissons have been used in the offshore industry in the last two decades as both temporary mooring anchorages and permanent foundation systems. Although there have been more than 500 suction caissons installed in various locations around the world,understanding of this concept is still limited.

Experimental Study of Installation of Concrete Suction Caisson in Clay
IFCEE 2015, 2015A suction caisson is installed by applying suction inside the caisson to create a downward net force to sink the caisson into soil. However, the applied suction pressure will also result in formation of a soil plug. This is particularly the case when the soil is soft and when the caisson wall is thick.

Variation of suction pressure during caisson installation in sand
Géotechnique, 2008A series of model tests was conducted in a geotechnical centrifuge to investigate the variation of suction pressure during caisson installation in dense sand. The tests were carried out for caissons of different size and surcharge (or effective weight).

A full numerical model for the installation analysis of suction caissons in sand
Ocean Engineering, 2021Abstract Safe installation of suction caissons requires a reliable preliminary study where soil resistance and other soil conditions are predicted with good accuracy. Past studies did not address the full problem when modelling the installation procedure of suction caissons in sand.

Large deformation analysis of suction caisson installation in clay
Canadian Geotechnical Journal, 2006Large deformation finite element (LDFE) analyses were performed to study the installation of caissons by suction and jacking in normally consolidated clay. The penetration of the caisson wall was modelled between depths of one and four diameters using an axisymmetric LDFE approach, which falls in the category of arbitrary Lagrangian–Eulerian (ALE ...

Design considerations of suction caisson foundations for offshore wind turbines in Southern China [PDF]
Applied Ocean Research, 2020 Suction caisson foundations are increasingly considered as a foundation solution for offshore wind farm development in China. This paper outlines the design considerations for developing a suction caisson supported jacket solution for an offshore wind ...

CPT-Based Method for the Installation of Suction Caissons in Sand
Journal of Geotechnical and Geoenvironmental Engineering, 2009A CPT-based method is presented for estimating the self-weight penetration and suction required during the installation of suction caissons in medium dense to dense sand. Existing methods, although fundamental in nature, suffer from the difficulty in estimating key input parameters such as an appropriate bearing factor for the tip resistance and ...

Reliability Based Installation Design of a Suction Caisson in Clay
2018The suction bucket jacket (SBJ) foundation has recently been deployed as a foundation solution in the offshore wind sector. Offshore wind farms are generally located in relatively shallow waters in relatively stiff soils, thus there can be a significant risk of early refusal when installing the SBJ.
