Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Dynamic Response of Marine Pile Foundation Under Combined Action of Wind and Wave Loads
In order to study the dynamic response of a single pile foundation under combined action of wind and wave loads in the marine environment, a three-dimensional unidirectional coupling numerical model of wind wave-seabed-single pile is established.

Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...

Decentralized Wind Energy Systems as Catalysts for Urban Resilience: A Design Framework
ABSTRACT Confronting the escalating extreme weather events (EWEs) and intensifying winds, this study proposes an active response to these issues by exploring decentralized wind energy production for Peng Chau Island, Hong Kong. It integrates theoretical perspectives on energy democracy—empowering local communities through energy autonomy—and urban ...

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 ...

ABSTRACT This study investigates the bearing capacity of tension piles and pile‐soil interaction during loading. Discrepancies between predicted and measured bearing capacities in previous tests motivated the study, where analytical methods showed considerable scatter and uncertainties in design.

Throughout their lifespan, monopile foundations supporting offshore wind turbines inevitably experience horizontal loads from waves, winds, and currents, resulting in cumulative deformation.

Idealized Offshore Low‐Level Jets for Turbine Structural Impact Considerations
ABSTRACT Low‐level jets (LLJs) describe conditions in which the wind speed reaches a local maximum with respect to altitude near the surface; they have been observed intermittently in the US mid‐Atlantic offshore environment. LLJs pose unique operating conditions for future wind turbines operating in the region, such as negative shear and locally ...

Scour Protection around Offshore Wind Turbines: Monopiles [PDF]
The flow processes in a scour protection around a mono-pile in steady current is described in relation to transport of sediment in the scour protection based on physical model tests. Transport of sediment in the scour protection may cause sinking of the scour protection. This may reduce the stability of the mono-pile and change for instance the natural
