Modal Identification Method of Offshore Wind Turbine Tower Based on SSI and FSDPC

Shock and Vibration, Volume 2026, Issue 1, 2026.
The structural health monitoring of offshore wind turbine towers is critical for ensuring their operational integrity. The condition of the tower structure is characterized by its modal parameters, which serve as effective health indicators. These parameters are identified through modal identification techniques.

Effect of ordering of cyclic loading sequences on the short-term performance of offshore monopiles in an overconsolidated clay

Applied Ocean Research
Wind and wave actions that vary in amplitude, frequency and direction cause irregular cyclic loading on monopiles supporting offshore wind turbines (OWTs), resulting in cumulative deformation.

Divergent Patterns in Wind Power Project Cost Overruns: How Scale Matters and Determinants of Construction Risk

Wind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT This study analyzes cost overruns in 80 wind power projects, focusing on the impact of configuration types and their interaction effects with other project characteristics. Using multiple regression analyses, including interaction terms and segmented regression, we investigate four key aspects of cost overruns in wind power projects. First, we

Dynamic Performance of Advanced Composite Towers in Offshore Wind Farms: Experimental and Numerical Investigation

Wind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT Conventional steel towers face challenges such as insufficient stiffness and structural instability, making them increasingly unsuitable for supporting large multi‐megawatt wind turbines. This study investigates the dynamic performance of concrete‐filled double‐skin steel tubular (CFDST) wind turbine towers as a novel structural member ...

Numerical analysis of offshore monopile foundations in layered clay

Applied Ocean Research
Monopiles are often embedded in layered soil profiles, where stratification significantly influences their lateral load response. However, much of the existing literature and proposed methodologies predominately focus on uniform soil profiles which is ...

Prediction of the Behaviour of Monopiles Under Drained Two‐Way Cyclic Lateral Loading in Sand

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 16, Page 3696-3712, November 2025.
ABSTRACT The monopile is considered as one of the preferred geotechnical foundations for the offshore wind energy converter; therefore, its cyclic behaviour is one of the major concerns in the design. In the current design approaches, the prediction of two‐way cyclic behaviour mainly depends on empirical equations, in which the specific site conditions

Self-weight Penetration Prediction Methods for Large Diameter Monopiles in Offshore Wind Farm

南方能源建设, 2020
[Introduction] Large diameter monopile is the most common used foundation in offshore wind projects. The Self Weight Penetration (SWP) usually takes up a large component of total penetration.

Creating a Real‐Time Capable Surrogate Model of a Wind Turbine Using Machine Learning

Wind Energy, Volume 28, Issue 11, November 2025.
ABSTRACT Multibody simulation (MBS) is an established method for modeling wind turbines for purposes such as load calculation. While capable of modeling wind turbines at high levels of detail, large MBS models can be computationally expensive. This makes deployment for real‐time critical use cases like digital twins difficult.
