Case studies on suction caisson foundations in offshore wind farms in China

International Journal of Geotechnical Engineering, 2020
Suction caissons are cylindrical-shaped foundation elements closed at the top and open at the bottom which are almost completely embedded with their cylindrical part in the soil.

Suction Caisson Foundation Design for Vortex-Induced Vibration Loading

All Days, 2003
Abstract Vortex induced vibration (VIV) can be an important source of loading on deepwater production structures, and one that is drawing increased attention in recent times. The fact that cyclic loading due to VIV can be an important foundation design issue is discussed for the first time in this paper.

Numerical Simulation of Ultimate Capacity of Suction Caisson Foundations by FEM

Applied Mechanics and Materials, 2012
As a newly developed type of foundation for deep water offshore and marine engineering, the suction caisson is usually subjected to combined loading of vertically uplift load, horizontal load and moment. Performance evaluation and design theory for such a new type of foundation can not meet the basic requirements of engineering practice sufficiently at

Suction caisson foundations for offshore wind turbines subjected to wave and earthquake loading: effect of soil–foundation interface

Géotechnique, 2014
The response of wind turbines founded on suction caissons and subjected to lateral monotonic, cyclic and earthquake loading is studied with due consideration of the role of soil–sidewall adhesion, using non-linear three-dimensional finite-element analyses.

Estimation of elastic and non-linear stiffness coefficients for suction caisson foundations

2015
ABSTRACT This paper investigates the stiffness of suction caisson foundations both in the elastic domain and when considering material and interface nonlinearities. First, at small strains, expressions from the literature are used to identify the stiffness matrix of a solid embedded foundation. Following, expressions for the stiffness

Deflection-Based Bearing Capacity of Suction Caisson Foundations of Offshore Wind Turbines

Journal of Geotechnical and Geoenvironmental Engineering, 2014
AbstractThe monocaisson foundation has become an important choice with the increasing demand of offshore wind turbines constructed in silt and sand seabeds in China. To guarantee the normal operation of the wind turbine, the angular rotation of the foundation should be strictly controlled.

Buoyant Tower: Experimental and Numerical Studies on Novel Application of Suction Caisson Foundation

Offshore Technology Conference
Abstract The buoyant tower, or BT, is a unique concept that stems from, and is a hybrid of, spar and compliant tower technologies. A BT is composed of one or a group of cylinders anchored to the seabed by a single suction caisson foundation (SCF). The BT rolls in a compliant manner while keeping the base from moving in any direction. The
