The platform is designed to weathervane freely around the turret to passively align the FOWT heading to the wind direction with yaw restoring function from a tailor-designed airfoil shaped A-frame tower. The passive alignment capability could potentially eliminate...

... negative interference while maximizing power output. Results indicated that an important number of locations of offshore oil and gas platforms were able to provide adequate levels of wind energy. Variable wind directions cause changes on the behavior of the turbulent wakes. Therefore, the layout of wind...

... The design of mooring systems in West of Africa is often dominated by squall events. These are episodes of rapidly increasing wind speeds accompanied with sudden and significant wind direction changes. The response of weathervaning systems (offloading tankers moored to an export system...

... dynamics. Our computational fluid dynamics simulations predict that when winds are aligned with the row, which is one of two predominant wind directions, wake-redirection control can create a 10% increase in energy capture efficiency. This means that, for a given wind energy plant's electrical generating...
