Effect of Embedment on the Plastic Behavior of Bucket Foundations

Journal of Waterway, Port, Coastal, and Ocean Engineering, 2015
A series of comprehensive research and development projects has validated the novel concept of the bucket foundation as an alternative to piled foundations, and bucket foundations are rapidly becoming a viable option for offshore wind farms and marginal fields.Within the last decade, experimental studies have indicated the possibility of defining ...

Undrained response of bucket foundations to moment loading

Applied Ocean Research, 2012
Bucket foundation as a large cylindrical structure that is open at the base and closed at the top, is recently being used within the offshore wind turbines projects. The bearing capacity of bucket foundations to moment loading in undrained soil is of interest particularly to the offshore geotechnical engineers.

Tensile capacity of offshore bucket foundations in clay

Ocean Engineering, 2020
Abstract Depending on the applications, offshore bucket foundations may be subjected to tensile loads. Mobilised soil resistance needs to resist the loads over the operation life of a project, or to be minimised if removal is required at decommission.

North Nemba Flare Bucket Foundations

Offshore Technology Conference, 2001
Abstract The successful installation of the North Nemba Flare in November 1999 demonstrates that suction-installed foundations ("buckets") are a competitive foundation solution for lightweight structures on soft cohesive soils.

A Case Study: Construction of Bucket Foundations for Jackup Ships

Volume 6: Polar and Arctic Sciences and Technology; Offshore Geotechnics; Petroleum Technology Symposium, 2013
Jackup ships are built to transport wind turbines foundation between offshore logistics center and the installation site. It require sufficiently stable seabed next to quay walls. Otherwise jackup processes may reduce the stability of the quay wall and remained footprints of the legs could induce unsafe jackup procedures in the future. Foundations have

Scour Development around Bucket Foundations

2015
The design without scour protection is a sensitive topic to most offshore developers, especially in the North Sea. However, newer research show that this concept is realistic if exists extended comprehension of the scour and backfill phenomena. The present paper shows comparative results for monopile and Bucket Foundation; using experimental analysis ...

Vertical bearing capacity of bucket foundations in sand

Ocean Engineering, 2016
Abstract Bucket foundations are widely used to support offshore structures. The vertical capacity of bucket foundations in clays has been extensively studied. However, the unique load transfer characteristics of bucket foundations in sands are not well documented.

Response of Cyclic-Loaded Bucket Foundations in Saturated Dense Sand

Journal of Geotechnical and Geoenvironmental Engineering, 2017
Abstract: One of the major concerns of designing offshore wind turbine foundations is to address the effects of cyclic loading coming from, especially, wave loading. This paper describes the results from a test series on a small-scale mono bucket foundation installed in water-saturated dense sand exposed to cyclic loading with 1.0 Hz. A macro model has

A comparison of the bearing capacity between shallow bucket foundations and solid foundations in clay

Ships and Offshore Structures, 2019
A shallow bucket foundation is a new foundation for offshore wind turbines with advantages of an anti-overturning bearing capacity and differential settlement control.

Instability of Bucket Foundations during Installation

2011
The bucket foundation is an upcoming technology for offshore wind turbines. The bucket foundation is a large cylindrical monopod foundation constructed as a thin steel shell structure. A bucket foundation does not require heavy installation equipment since it is installed by suction forces.
