چکیده
This paper aims at investigating the effect of water depth increase on global performance a floating offshore wind turbine, with special focus environmental loading effects and turbine operating status. An integrated aero-hydro-servo-elastic (AHSE) analysis was simulated in time domain. The model first validated against published results terms mooring system restoring force platform natural frequencies. considered is between 200 300 m, which deep-water range used current (FOWT) industry. In this study, both normal failure conditions were considered. Key conclusions from case studies indicated that, based range, heave motion slack configurations line top tension are more sensitive to depth. Water influences tower base bending when has high-speed shaft brake due grid loss, but restricted high-frequency response (>2 Hz) less obvious than lines.

Effect of Platform Surge Motion on the Performance of 5MW NREL Offshore Floating Wind Turbine
In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...
متن کاملVertical Wave Impacts on Offshore Wind Turbine Inspection Platforms
Breaking wave impacts on a monopile at 20 m depth are computed with a VOF (Volume Of Fluid) method. The impacting waves are generated by the second-order focused wave group technique, to obtain waves that break at the position of the monopile. The subsequent impact from the vertical run-up flow on a horizontal inspection platform is computed for five different platform levels. The computational...
متن کاملEvaluation of Turbulence on the Dynamics of Monopile Offshore Wind Turbine under the Wave and Wind Excitations
In recent years, the use of offshore wind turbines has been considered on the agenda of the countries which have a significant maritime boundary due to more speed and stability of wind at sea. The aim of this study is to investigate the effect of wind turbulence on the aero-hydrodynamic behavior of offshore wind turbines with a monopile platform. Since in the sea, the wind turbine structures ar...
متن کاملFoundation damping and the dynamics of offshore wind turbine monopiles
The contribution of foundation damping to offshore wind turbines (OWTs) is not well known, though researchers have back-calculated foundation damping from “rotor-stop” tests after estimating aerodynamic, hydrodynamic, and structural damping with numerical models. Because design guidelines do not currently recommend methods for determining foundation damping, it is typically neglected. This pape...
