Tsunami-induced scour around monopile foundations [PDF]

Coastal Engineering, 2017
Abstract A fully-coupled (hydrodynamic and morphologic) numerical model is presented, and utilized for the simulation of tsunami-induced scour around a monopile structure, representative of those commonly utilized as offshore wind turbine foundations at moderate depths i.e. for depths less than 30 m.

Numerical Study on Lateral Response of Offshore Monopile in Sand under Local Scouring Conditions

Journal of Marine Science and Engineering, 2023
Currently, p-y models have been broadly adopted for estimating the lateral bearing capacity of large-diameter monopiles in offshore engineering. However, the existing p-y curves cannot reflect the effect of pile diameter D on the lateral response of ...

Influence of Pile Diameter and Aspect Ratio on the Lateral Response of Monopiles in Sand with Different Relative Densities

Journal of Marine Science and Engineering, 2021
The large-diameter monopiles are the most preferred foundation used in offshore wind farms. However, the influence of pile diameter and aspect ratio on the lateral bearing behavior of monopiles in sand with different relative densities has not been ...

Model Uncertainties for Soil-Structure Interaction in Offshore Wind Turbine Monopile Foundations

Journal of Marine Science and Engineering, 2018
Monopiles are the most common type of foundation used for bottom-fixed offshore wind turbines. This investigation concerns the influence of uncertainty related to soil–structure interaction models used to represent monopile–soil systems.

The advanced p-y method for analyzing the behaviour of large-diameter monopiles supporting offshore wind turbines [PDF]

E3S Web of Conferences, 2020
The analyses of monopile foundations have been heavily based on the p-y response curves (to represent lateral soil resistances) published by API RP 2GEO (2011) and DNV (2013), which are proven reliable and applicable for piles with smaller diameters that
