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.

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

Simplified Model for the Stiffness of Suction Caisson Foundations Under 6 DOF loading

2017
Suction caisson foundations are increasingly used as foundations for offshore wind turbines. This paper presents a new, computationally efficient, model to determine the stiffness of caisson foundations embedded in linearly elastic soil, when subjected to six degree-of-freedom loading; vertical (V), horizontal (Hx, Hy), overturning moment (Mx, My) and ...

Feasibility of Suction Caisson Solutions for the Foundations of Offshore Jacket Platforms in the Persian Gulf

Volume 2: Structures, Safety and Reliability, 2008
This paper gives the results of an investigation into the performance of the suction caisson foundations for jacket platforms in the Persian Gulf under quasi static environmental wave loading. A numerical approach has been chosen to study the subject. The installation phase has not been analysed, so the suction caisson foundations have been considered ...

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
