Installation and Pullout of Suction Caissons: Finite-Element Simulation
Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003This paper reports on the development of computational tools at the Offshore Technology Research Center to study the behavior of suction caissons also known as suction anchors and bucket foundations. The effects of installation on axial capacity are examined through simulation of caisson penetration into clayey soil by self-weight and suction.

Installation and Axial Pullout of Suction Caissons: Numerical Modeling
Journal of Geotechnical and Geoenvironmental Engineering, 2010We outline the development of a computational procedure for finite-element analysis of suction-caisson behavior, highlighting its unique features and capabilities. The procedure is based on a description of clayey soil as a two-phase medium: a water-filled porous solid. Nonlinear behavior of the solid phase is represented by means of a bounding-surface

Experimental Study of Suction Installation of Caissons in Dense Sand
23rd International Conference on Offshore Mechanics and Arctic Engineering, Volume 1, Parts A and B, 2004Physical models have been developed to investigate suction installation of caisson foundations in fine-grained dense silica sand. The main controlling factor, pumping rate, was found to have significant influence on the differential pressure result across the caisson base.

Suction Caisson Anchor and Dynamically Installed Fish Anchor in Calcareous Silt
Volume 9: Offshore Geotechnics; Petroleum Technology, 2023Abstract Suction caisson anchors are proven reliable anchoring solutions for tethering floating facilities in shallow to deep water. Dynamically installed anchors have been identified as the most cost-effective option for particularly deep water developments. Recently, the dynamically installed fish anchor has been introduced, adopting a

Numerical Investigation Into Parameters Influencing the Installation of Suction Caissons in Sand
Volume 2: Structures, Safety and Reliability, 2008This paper reports results from a numerical investigation into the suction caissons penetration in sand. Two dimensional axisymmetric models have first been calibrated and verified against several laboratory and field test data from other researchers. Soil nonlinearities and soil/caisson interactions have been taken into account.

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

Installation of suction caissons for offshore renewable energy structures
2010Offshore renewable energy structures, such as wind turbines or tidal turbines, might use suction caissons as foundations. One of the key processes is the design for the installation as this is where substantial cost savings could be made. A number of different approaches for assessing the installation suction, and other associated installation ...

Installation and Lateral Resistance of Model Suction Caissons in Sandy Ground
Advanced Materials Research, 2014Suction caissons attract the attention as the foundation of offshore wind turbines. Installation and resistance behaviors of the suction caisson are important factors for the design of foundation. An installation behavior into sandy seafloor was discussed by using a model suction caisson and the failure surfaces in the aluminum rod mass, as the model ...

Investigation on Seepage Erosion and Safety Mechanism of Suction Caisson Installation
2018The suction caisson foundation is a hollow cylinder with a closed top lid and is penetrated into seabed by applying suction inside the caisson. The suction pressure leads to a downward push force and induces a seepage flow to reduce the effective stress in the soil plug.
