An Investigation into the Effect of Scour on the Loading and Deformation Responses of Monopile Foundations

Energies, 2017
Severe foundation scour may occur around monopile foundations of offshore wind turbines due to currents and waves. The so-called p-y curves method is suggested in the existing design recommendations to determine the behavior of monopiles unprotected ...

The Effect of Lateral Loading Parameters on Monopile Behavior Based on Physical Modeling

نشریه مهندسی دریا, 2019
Monopiles are the most common type of foundation for offshore wind turbines (OWT). Monopiles have been used in more than 80% of the offshore wind turbines.

Effect of Combined Wave and Current Loading on the Hydrodynamic Characteristics of Double-Pile Structures in Offshore Wind Turbine Foundations

Energies
The multi-pile structure is a common and reliable foundation form used in offshore wind turbines (such as jacket-type structures, etc.), which can withstand hydrodynamic loads dominated by waves and water flow, providing a stable operating environment ...

Research on deformation evolution mechanism of monopile-seabed system in offshore wind farm based on UWFBG

Journal of Ocean Engineering and Science
The deformation behavior of offshore wind turbine monopiles under long-term environmental loading remains insufficiently understood, largely due to the absence of continuous in-situ measurements capable of resolving depth-dependent pile–soil interaction.

Wave Loads on Monopile Structures

, 2017
This article compares different approaches to determine the design forces and moments for the ultimate limit state for monopile structures for offshore wind turbines. The principles of the different approaches are explained. Four different methods, i.e.

Centrifuge and Numerical Investigations on Responses of Monopile-Supported Offshore Wind Turbines with Riprap Scour Protection Under Earthquakes

Journal of Marine Science and Engineering
Riprap scour protection is commonly employed to protect against local scour around large-diameter monopile foundations for offshore wind turbines (OWTs), and considering its influence on the static and dynamic behavior of monopiles may also provide the ...

Comparative Study on Wave Elevations Downstream of Monopile- and Jacket-Mounted Offshore Wind Turbines

Journal of Marine Science and Engineering
Offshore wind turbines, especially the fixed-bottom type, have been commercialized and installed in recent years. Generally, an offshore sub-structure such as a monopile or a jacket foundation is adopted to secure offshore wind turbines.

Monopile response to scour and scour protection

, 2020
Scour of seabed sediments can occur around offshore structures, the resultant reduction in strength and stiffness of the structure’s foundations presents operational challenges for monopile-supported offshore wind turbine structures. Turbines are at risk of reduced operation or even premature decommissioning if scour causes the natural frequency of a ...
