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

The interannual variations of installed capacity for offshore wind turbines in China: estimations derived solely from remote sensing

Geo-spatial Information Science
Accurately and thoroughly determining the installed capacity of offshore wind turbines (OWTs) and offshore wind farms (OWFs) is crucial for evaluating offshore wind energy and guiding future development.

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.

Determination of wind turbine far wake using actuator disk [PDF]

, 2014
The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of upcoming wind cannot be valid. The

A reliability-constrained optimisation framework for offshore wind turbine support structures

International Journal of Sustainable Energy
A new approach that links finite element analysis (FEA) and a genetic algorithm (GA) with Monte Carlo simulation (MCS) for the reliability-constrained optimal design of offshore wind turbine (OWT) support structure is presented.

Semi-Active Structural Control of Offshore Wind Turbines Considering Damage Development

Journal of Marine Science and Engineering, 2018
High flexibility of new offshore wind turbines (OWT) makes them vulnerable since they are subjected to large environmental loadings, wind turbine excitations and seismic loadings.

Application of an Eddy Current-Tuned Mass Damper to Vibration Mitigation of Offshore Wind Turbines

Energies, 2018
Offshore wind turbine (OWT) structures are highly sensitive to complex ambient excitations, especially extreme winds. To mitigate the vibrations of OWT structures under windstorm or typhoon conditions, a new eddy current with tuned mass damper (EC-TMD ...

Experimental investigation and welding modelling of improved fatigue TMCP steels for Offshore Wind Turbine (OWT) support structures

With offshore wind deployment accelerating, thick-section steel structures must be reliable, weldable, and economically manufactured. Thermo-mechanically controlled processed (TMCP) steels, such as S355ML, are widely adopted for offshore wind turbine (OWT) support structures (e.g., monopiles and transition pieces) because they combine high strength ...
