Temporary modification strategies of Vibration Dampers for Offshore Wind Turbines

Trends towards higher capacity offshore wind turbines (OWTs) and deeper offshore wind farm sites, make wave-induced vibrations more dominant in its design. During idling phases of these next-generation OWTs, additional damping is required. This can be achieved through dynamic vibration absorbers (VAs), i.e. dampers. More importantly, wave...

Mitigating ice-induced offshore wind turbine vibrations utilizing a TMD system

Offshore wind farms in Bohai Bay may be exposed to sea ice. The possible development of ice-induced vibrations can result in periodic high amplitude oscillations of the structure, which can significantly contribute to the fatigue of the structure. The main objective of this thesis is to investigate the mitigation effects of ice-induced...
