Feasibility studies of a converter-free grid-connected offshore hydrostatic wind turbine [PDF]

open access: yes, 2020
Owing to the increasing penetration of renewable power generation, the modern power system faces great challenges in frequency regulations and reduced system inertia.

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

open access: yesWind 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 ...

Large-scale experimental study on scour around both slender and large monopiles under irregular waves

open access: yesWater Science and Engineering
Offshore wind power plays a crucial role in energy strategies. The results of traditional small-scale physical models may be unreliable when extrapolated to large field scales.

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

open access: yesInternational 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

Soil Interaction and Grout Behavior for the NREL Reference Monopile Offshore Wind Turbine

open access: yesJournal of Marine Science and Engineering, 2020
Monopiles for offshore wind are the most used foundations by farm operators due to their low production costs, when compared to other bottom-fixed or floating foundations.

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

open access: yesWind 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.

Monopile Implementation in Offshore Bridge

open access: yesInternational Journal For Multidisciplinary Research
This paper presents an in-depth analysis of the implementation of monopiles in offshore and overwater bridge construction. Monopiles, cylindrical steel structures driven into the seabed or riverbed, have gained prominence as a foundation solution due to their cost-effectiveness, ease of installation, and environmental benefits.

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

open access: yesce/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.
