Dynamics of a semi-submersible offshore floating multi-wind-turbine platform
This research aims to design a novel semi-submersible platform for installing multiple turbines and analyze the aero-hydrodynamic responses of the platform operating under wind-wave conditions that can reduce the installation and mooring costs. The potential of wind power increases as we go further into the offshore. Extracting wind energy from offshore wind resources in deep water gives a chance to advance in expanding power generation from renewable resources. In this study, a review of the dynamics of existing floating platform concepts is investigated to evaluate the research gap to find a more effective platform for installing multiple wind turbines. The wake interference between the wind turbines on a multi-wind-turbine platform causes the performance drop in the downstream wind turbines hence, it is necessary to analyze the wake effects in the initial phase of the design. The wake effect analysis is performed using the Larsen wake model and CFD simulations on three probable platform choices to choose the best possible platform to design the multi-wind-turbine platform. The offshore floating platform studied in this report supports five 8 MW wind turbines. Hydrostatic analysis of the platform is done to study the floating stability behavior of the platform. The first order hydrodynamics and wave loadings on the platform are calculated in the frequency domain using the potential flow linear diffraction model. The hydrodynamic analysis is carried out on the platform to predict the wave-body interaction between the platform and the waves. The aero-hydrodynamic analysis of the multi-wind turbine platform has been carried out to comprehend the dynamic responses of the platform operating under coupled wind-wave loads. The aerodynamic loads due to wind speed on the wind turbines and hydrodynamic loads due to wind and waves on the overall system are evaluated. The dynamics of a wind turbine considering the five-degree of freedom are formulated and an adaptive control algorithm is developed for the pitch and torque ...
