Study on the Structural Vibration Control of a 10 MW Offshore Wind Turbine with a Jacket Foundation Under Combined Wind, Wave, and Seismic Loads

Journal of Marine Science and Engineering
As offshore wind power continues to develop, with increased capacity and ability to function in deeper waters, jacket-type offshore wind turbines (OWTs) are becoming increasingly challenged by complex environmental loads and significant structural ...

Investigation of Site-Specific Wind Field Parameters and Their Effect on Loads of Offshore Wind Turbines

Energies, 2012
The main contributing factors to unsteady loading of Offshore Wind Turbines (OWT) are wind shear, turbulence, and waves. In the present paper, the turbulence intensity and the wind shear exponent are investigated.

Effect of gap size on flange face corrosion

Materials and Corrosion, Volume 76, Issue 6, Page 833-850, June 2025.
This study investigates the effect of gap size on the flange face corrosion behavior in bolted flanged joints of wind turbine towers exposed to challenging offshore conditions. Using electrochemical techniques, it finds that increasing the gap thickness accelerates the general corrosion rate and delays crevice corrosion initiation.

Structural Optimization and Comparison Study of Different Configurations of Offshore Wind Turbine Jacket Substructures

Wind Energy, Volume 28, Issue 5, May 2025.
ABSTRACT In this work, the design of a three‐legged jacket is presented, taking into account the susceptibility to the directionality of the loads in comparison with a four‐legged jacket. For this purpose, two jackets with different orientations with respect to the incoming environmental loads were modelled: the G30, which has two legs facing the main ...

Influence of Seismic Direction on Dynamic Responses of Wind Turbine in Operation: An Experimental Study by Combining Wind Tunnel and Shaking Table Tests

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 5, Page 1417-1432, 25 April 2025.
ABSTRACT This study investigates dynamic responses of wind turbines subjected to combined seismic and wind loads, with a particular focus on the influence of seismic input angles and the effect of aerodynamic damping. A wind tunnel‐shaking table (WTST) test platform was developed, capable of applying seismic and wind loads simultaneously. A 1:100 scale

Scenario-based LCA for assessing the future environmental impacts of wind offshore energy: An exemplary analysis for a 9.5-MW wind turbine in Germany

Energy, Sustainability and Society
Background Offshore wind energy (OWE) will play a significant role in achieving climate neutrality. For example, several scenarios for Germany (e.g., Kopernikus base, Kopernikus 1.5 degree, Prognos CN65, and CN60) depict substantial OWE annual installed ...

Flume test on mechanical responses of wind-wave cyclic loaded offshore wind turbine supported by jacket foundation considering time-varied local scour effects

Applied Ocean Research
Large diameter pile (LDP) jacket foundations have recently seen increased application in offshore wind energy engineering due to their ability to avoid the complexities of rock-socketed pile construction.

Soil Masing Behaviour for Offshore Wind Turbines—Fatigue Design and a Simple Damping Model

Wind Energy, Volume 28, Issue 3, March 2025.
ABSTRACT Fatigue damage accumulation for offshore wind turbines is highly dependent on damping of the structure and particularly on the soil damping contribution during idling conditions. This paper presents an efficient method to estimate soil damping specific to wind turbine design and offshore environmental conditions.

Assessment of natural frequency of installed offshore wind turbines using nonlinear finite element model considering soil-monopile interaction

Journal of Rock Mechanics and Geotechnical Engineering, 2018
A nonlinear finite element model is developed to examine the lateral behaviors of monopiles, which support offshore wind turbines (OWTs) chosen from five different offshore wind farms in Europe.
