A Feasibility Study for Using Fishnet to Protect Offshore Wind Turbine Monopile Foundations from Damage by Scouring

Applied Sciences, 2019
Offshore wind turbine monopile foundations are subjected to complex wind, wave, and flow coupling effects, which result in seabed scouring around the monopile.

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

Validation and Application of a New Software Tool Implementing the PISA Design Methodology

Journal of Marine Science and Engineering, 2020
The PISA (Pile Soil Analysis) research project has resulted in a new methodology for the design of offshore wind turbine monopile foundations. A new software tool called PLAXIS Monopile Designer (MoDeTo) has been developed that automates the PISA design ...

Qualifying and quantifying offshore wind farm-generated noise [PDF]

, 2013
The construction, operation and dismantling of offshore wind farms generate noise both above and under water that may be of environmental concern. The maximum detected sound power level of the above water pin piling noise for example, reached 145 dB(A ...

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 ...

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

Uncertainties in the design of support structures and foundations for offshore wind turbines [PDF]

, 2014
Offshore wind industry has exponentially grown in the last years. Despite this growth, there are still many uncertainties in this field. This paper analyzes some current uncertainties in the offshore wind market, with the aim of going one step further in

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.

Assessment of the Distribution of the Gaps Between Ring Flange Connections in Offshore Wind Turbines

ce/papers, Volume 8, Issue 3-4, Page 289-297, September 2025.
Abstract Ring flange connections are commonly used to connect the tower of offshore wind turbines with monopile foundations. Studs in these ring flange connections are sensitive to fatigue damage accumulation, which is aggravated by gaps between the flanges. Such gaps are inevitable because of imperfections (out‐of‐flatness) of the flanges.
