This paper was developed in cooperation between the TUHH and Overdick GmbH & Co. KG. The goal of the presented work is gaining further knowledge about the installation and bearing behavior of suction bucket foundations for fixed offshore platforms based on sand. Buckets are usually made of steel and consist of a cylinder and a lid at

On cyclic performance of suction bucket foundations in cohesionless soils
International Journal of Physical Modelling in GeotechnicsAn alternative to monopiles to support offshore wind turbines is the use of jacket structures founded on suction buckets. These foundations have been successfully deployed in recent developments and have proven to be a viable foundation concept due to their relatively fast and low-noise installation, as well as their general applicability for a wide ...

Centrifuging for Penetration of Ellipse Suction Bucket of Breakwater into Clay Ground
Advances in Soil Dynamics and Foundation Engineering, 2014In order to build new offshore breakwater on weak ground, prefabricated thin-walled structures are often considered as its foundation. Integrated into a preliminary design study for a prototype breakwater to be built, a series of geotechnical centrifuge model tests are carried out to investigate the penetration behavior of a large thin-walled ellipse ...

Installation of Bucket Foundations and Suction Caissons in Sand - Geotechnical Performance
Offshore Technology Conference, 1999Abstract This paper describes the important geotechnical principles relating to the installation of bucket foundations in dense sand, where 'suction' pressures are applied to both increase the static driving force, and more importantly, to degrade the penetration resistance. The paper will present a series of finite

Comparison of numerical formulations for the modeling of tensile loaded suction buckets
Computers and Geotechnics, 2017The tensile resistance of a suction bucket is investigated using three different numerical formulations. The first formulation utilizes the three-field u-p-U formulation accounting for solid and fluid displacements, u and U, as well as the pore-fluid pressure, p.

Capacities and failure modes of suction bucket foundation with internal bulkheads
Journal of Ocean University of China, 2017Suction bucket foundations can be divided into four compartments by cruciform internal bulkheads, thereby yielding better capacity in certain conditions than those without internal bulkheads. As yet, no systematic study has been conducted regarding the effects of cruciform internal bulkheads on the capacities of suction bucket foundations.

Visualisation of mechanisms governing suction bucket installation in dense sand
2018© 2018 Taylor & Francis Group, London. Suction buckets are an increasingly considered foundation option for offshore wind turbines. Although the required suction can be predicted well using existing methods, uncertainty remains around some input parameters, because the effects of suction installation on the soil state are not understood in detail ...

Tensile-loaded suction bucket foundations for offshore structures in sand
2020Currently, a great demand for renewable energy exists and OWT supply a relevant share, which is expected to further increase in the future. The foundations for these structures must fulfill strict requirements to ensure a safe and reliable operation of the OWT while minimising the costs.
