Finite element analysis of cyclic lateral responses for large diameter monopiles in clays under different loading patterns

Computers and Geotechnics, 2021
It is very important to analyze the lateral cyclic response of monopiles for the design of offshore wind turbines (OWTs). A three-dimensional finite element method for lateral cyclic responses of large-diameter monopiles is developed based on a ...

Probabilistic calibration of the p-y method considering model uncertainty for ultimate limit state design of monopiles

Georisk: Assessment and Management of Risk for Engineered Systems and Geohazards, 2023
The API p-y method is widely used in the design of offshore wind turbines (OWTs) monopiles at present. This study systematically evaluates the model uncertainty of the p-y method for OWT monopiles and proposes a two-stage calibration approach for ...

Hydro-mechanical modelling of interaction between monopiles and cross-anisotropic sandy seabed subjected to wave loadings

Geomechanics and Geoengineering, 2023
Cross-anisotropy is a typical feature of marine sediments. To explore the monopile-seabed interaction in cross-anisotropic sandy seabed subjected to wave loadings, a hydro-mechanical model is established and the nonlinear monopile-soil contact behaviours

Increasing the Lateral Resistance of Offshore Monopile Foundations: Hybrid Monopile-Footing Foundation System

Proceedings of the 2012 (3rd) International Conference on Engineering, Project, and Production Management, 2012
Due to the limitations of locations some of the recently found offshore oil and gas reservoirs, or the proposed locations for some of the offshore wind farms, there is clearly scope for developing foundations that are more efficient. One approach in increasing the lateral load bearing capacity of monopile foundations is the ‘hybrid’ monopile-footing ...

Deflection of Monopiles with Collar Caissons

Journal of the Geotechnical Engineering Division, 1981
The discovery of small reserves of gas does not, in general economically justify the investment required for construction of conventional offshore platforms. In this context, the development and economic advantages of monopode platforms for drilling and producing gas wells, in water depths of the order of 100 ft (30 m).

Numerical study on the stiffening properties of scour protection around monopiles for Offshore Wind Turbines

Engineering Geology
An active marine seabed causing scour around monopile foundations has to be addressed as a geological hazard. These structures are often protected with rock armour to prevent foundation failure.

Load history idealization effects for design of monopiles in clay

Geotechnique, 2022
Evaluation of the characteristic behaviour of clay under cyclic loading is desirable and essential for an optimised monopile design of offshore wind turbines (OWT).
