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 ...

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 ...
