... simulation, and the platform motions are solved by the potential theory. The complex ABL inflow is generated using a precursor LES method with long-enough time to obtain the quasi-equilibrium state turbulence. And the calculation results are compared with the uniform wind inflow. The oscillation amplitude...

... instantaneously by a simple and robust model. Based on the proposed method, sensitivity studies were conducted to investigate the influence of the oscillation amplitude and period on the anchor load. It is concluded that the maximum anchor load is more sensitive to the oscillation amplitude rather than the period...
