In this study, a resonance avoidance control algorithm was designed to address the tower problem of semi-submersible floating offshore wind turbine (FOWT) and dynamic performance turbine, floater platform, mooring lines at two exclusion zone ranges were evaluated. The simulations performed using Bladed, commercial software for analysis. length simulation analysis response six degrees freedom (D...

Offshore wind turbine is now being seriously considered as a crucial energy source to achieve not only CO2 reduction, but also to meet the enormous power shortages that occur in India and around the world. Nevertheless offshore wind energy is not competitive as on today with other sources of energy. There are combination of some select technologies which could bring about improvement in offshor...

Dual-Doppler lidar is a powerful remote sensing technique that can accurately measure horizontal wind speeds and enable the reconstruction of two-dimensional wind fields based on measurements from two separate lidars. Previous research has provided a framework of dual-Doppler algorithms for processing both radar and lidar measurements, but their application to wake measurements has not been add...

As a complex multi degree of freedom coupling system, floating offshore wind turbine usually works in and changeable marine environment. The research often needs to consider the effect wind, wave current at same time. Under action load, will produce large motion response. Generally, surge pitch are most obvious aspects, their amplitude is also largest, large-scale platform directly affect relat...
