Penetration and Pullout Capacity of Low-Skirted Suction Caissons [PDF]
Shock and Vibration, 2021 The bearing capacity of suction caissons is the key to the design of offshore structures. A new type of cross-shaped low-skirted suction caisson is invented to effectively improve the bearing capacity, considering inevitable “soil plug” phenomenon.

Failure envelope considering the ultimate tensile capacity of suction caissons in sand
Soils and Foundations, 2023 Little analytical work has been done to elucidate the ultimate capacity of suction caissons under vertical tensile (V), lateral (H), and moment (M) loads in soils.

Dynamic lateral response of suction caissons [PDF]
Soil Dynamics and Earthquake Engineering, 2017 Abstract Deeper water installations of offshore wind turbines may be supported by jacket structures. This study investigates the dynamic response of suction caissons for jackets by analysing 3D finite element models in the frequency domain. The numerical modelling was firstly validated by analytical solutions for pile foundations.

A standard formulation for the installation of suction caissons in sand
Journal of Ocean Engineering and Science, 2019 Suction assisted installation of caisson foundations in sand relies on the developed seepage around the caisson wall. Seepage is known to produce soil loosening inside the caisson cavity and an overall reduction in soil resistance to caisson penetration.

Suction caissons subjected to monotonic combined loading [PDF]
, 2016 Suction caissons are being increasingly used as offshore foundation solutions in shallow and intermediate water depths. The convenient installation method through the application of suction has rendered this type of foundation as an attractive alternative to the more traditional monopile foundation for offshore wind turbines.

Impedance of flexible suction caissons [PDF]
Earthquake Engineering & Structural Dynamics, 2007 AbstractThe dynamic response of offshore wind turbines is affected by the properties of the foundation and the subsoil. The aim of this paper is to evaluate the dynamic soil–structure interaction of suction caissons for offshore wind turbines. The investigations include evaluation of the vertical and coupled sliding–rocking vibrations, influence of the

Vertical Stiffness Functions of Rigid Skirted Caissons Supporting Offshore Wind Turbines
Journal of Marine Science and Engineering, 2021 Suction Bucket Jackets (SBJs) need to be fundamentally designed to avoid rocking modes of vibration about the principal axes of the set of foundations and engineered towards sway-bending modes of tower vibration.

Solid-Fluid Coupled Numerical Analysis of Suction Caisson Installation in Sand
Journal of Marine Science and Engineering, 2021 Suction caissons are widely used foundations in offshore engineering. The change in excess pore pressure and seepage field caused by penetration and suction significantly affects the soil resistance around the caisson wall and tip, and also affects the ...
