The S-bos floating wind platform, designed by BlueNewables, is a spar-type concept that intends to reduce the installation and transportation and maintenance costs while providing outstanding stability under harsh wind and waves regimes.
The main objective of this master thesis is the so-called coupled assessment of the S-bos platform.
The implementation is to be performed in an aero-hydro-servo-elastic numerical model. Modelling the S-bos platform poses challenges product of the existence of diffraction, inertial and viscous forces for different wave regimes. Neither Morison’s equation nor potential flow theory can reliably predict the dynamic response of the structure to the wave loading alone. The floating substructure is a combination on Morison and Froude Krylov elements that need to be properly considered on the numerical model.
Furthermore, the numerical models will be validated against experimental scaled tests.
The 10MW wind turbine and the tower will be modelled considering the elasticity of tower and blades. The control of the wind turbine will be tuned to minimize the pitch motions of the floater and to avoid the negative damping effect.
Once the fully coupled model is set, the analysis will be performed considering a selection of critical load-cases following international standards on floating wind platforms design.
