Numerical Analysis of the Effect of Offshore Turbulent Wind Inflow on the Response of a Spar Wind Turbine
Putri, Rieska Mawarni; Obhrai, Charlotte; Jakobsen, Jasna Bogunovic; Ong, Muk Chen (Peer reviewed; Journal article, 2020)Turbulent wind at offshore sites is known as the main cause for fatigue on offshore wind turbine components. Numerical simulations are commonly used to predict the loads and motions of floating offshore wind turbines; ... -
Offshore Wind Turbine Loads and Motions in Unstable Atmospheric Conditions
Putri, Rieska Mawarni; Obhrai, Charlotte; Knight, Julie-Ann Marie (Peer reviewed; Journal article, 2019)Even though it is widely known that unstable atmospheric stability conditions can lead to higher turbulence, the use of proper turbulent wind models considering unstable conditions are not often used in the simulation of ... -
Response sensitivity of a semisubmersible floating offshore wind turbine to different wind spectral models
Putri, Rieska Mawarni; Obhrai, Charlotte; Jakobsen, Jasna Bogunovic (Peer reviewed; Journal article, 2020)Previous research on the OC3 spar floating offshore wind turbine (FOWT) has shown the sensitivity of the yaw and side-side modes' load and motion responses to different atmospheric conditions. Using the same baseline turbine ... -
Turbulence in a coastal environment: the case of Vindeby
Putri, Rieska Mawarni; Cheynet, Etienne; Obhrai, Charlotte; Jakobsen, Jasna Bogunovic (Journal article; Peer reviewed, 2022-08-11)The one-point and two-point power spectral densities of the wind velocity fluctuations are studied using the observations from an offshore mast at Vindeby Offshore Wind Farm, for a wide range of thermal stratifications of ... -
Wind-induced response of an offshore wind turbine under non-neutral conditions: A comparison with Hywind Scotland
Putri, Rieska Mawarni; Obhrai, Charlotte (Peer reviewed; Journal article, 2022)In this study, aeroelastic simulations of a 5 MW spar wind turbine are performed by using simulated wind fields that are representative of surface layer marine atmospheric turbulence under different atmospheric stratifications. ...
