Design procedures for installation of suction caissons in clay and other materials

Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2005
Suction-installed skirted foundations, often referred to as suction caissons, are increasingly being used for a variety of offshore applications. In designing a caisson a geotechnical engineer must consider the installation process as well as the in-place performance.

Suction caissons in dense sand, part I: installation, limiting capacity and drainage [PDF]

Géotechnique, 2018
Suction caissons are a promising foundation concept for supporting offshore wind turbines. Compared to applications in the oil and gas industry, where most practical experience exists, significant differences arise in terms of load paths and magnitudes, soil type and caisson aspect ratio (skirt length to diameter).

The impact of geotechnical spatial variability on the installation of suction caisson anchors [PDF]

Over the past decade, the offshore wind industry has evolved with significant technological advances. These have been driven by the need for offshore wind energy to provide cost-competitive renewable energy. The economics of offshore wind necessitates lean and efficient designs and nowhere is this more prevalent than in anchors for floating wind ...

A simplified procedure for the prediction of liquefaction‐induced settlement of offshore wind turbines supported by suction caisson foundation based on effective stress analyses and an ML‐based group method of data handling

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 15, Page 5072-5098, December 2023., 2023
Abstract In this research, a series of non‐linear dynamic finite element (FE) effective stress analyses were conducted to analyze the influence of the suction caisson geometry, ground motion intensity and contact pressure caused by the offshore wind turbine (OWT) on the settlement pattern and seismic demand of the OWT's structure on saturated dense ...

A theoretical and practical framework based on plasticity theory for the drained behavior of single and multiple shallow footings

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 16, Page 2872-2898, November 2023., 2023
Abstract With the shift of the offshore wind energy sector to deeper waters, demand for the development of more complex foundation solutions, particularly suction bucket – supported tripod/tetrapod and jacket foundations, has increased. This paper is divided into two main sections.

Geotechnical Performance of Suction Caisson Installation in Multi-layered Seabed Profiles [PDF]

, 2018
Suction caissons consist of large cylindrical buckets made from steel. In order to serve as foundations for various offshore structures, suction caissons are pushed into the seabed under pressure differential exerted on their lid by an imposed suction ...

Centrifuge tests on a soil plug removal method for suction caisson during installation

Applied Ocean Research
The suction caisson is one of the most widely adopted foundation systems for supporting offshore wind turbines and anchoring floating platforms. During suction-assisted installation, the soil inside the caisson may heave and form a soil plug that ...

Geopower, Geos and the Colonisation of Palestine

Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
ABSTRACT While the majority of geographical work on colonialism in Palestine centres on territory and land, this article foregrounds geopower and geos in the making of spatial relations. Three arguments are made over three corresponding sections. The first draws on recent writing on geopower and geos (primarily that by Elizabeth Grosz, Elizabeth ...
