Abstract

In view of the situation where fatigue failure is prone to occur in offshore wind power structures

a novel damping device has been proposed for a 10 MW offshore wind turbine based on a monopile. The efficacy of the damping device has been validated through a combination of model testing and numerical analysis. The model test demonstrates that the structural damping is increased by 52.59% and 103.11% due to the damping device

when the additional masses are 1.450 kg and 2.175 kg

respectively. The results of model numerical analysis align closely with the results of model test

thereby substantiating the reliability of the numerical analysis. The numerical analysis of the prototype demonstrates that the damping ratiio is enhanced by 36.17% and 65.11% due to the damping device when the additional masses are 50 t and 100 t

respectively. This evidence substantiates the efficacy of the new damping device in improving the structural damping of offshore wind turbines.
