20160114863 | CONNECTION SYSTEM FOR ARRAY CABLES OF DISCONNECTABLE OFFSHORE ENERGY DEVICES - A floating connector of an offshore energy device and a method for connecting the floating connector is provided. The floating connector includes a buoy having a long spar like floater, where the buoy provides buoyancy to the floating connector. The floating connector further includes at least two cables for connecting to the offshore energy device. The floating connector also includes a joint box for coupling to the offshore energy device and for providing an electrical connection of the at least two cables to a switchgear of the offshore energy device. When the joint box is coupled to the offshore energy device, an electrical circuit with the at least two cables is completed through the offshore energy device via the switchgear. | 04-28-2016 |
20140339828 | SYSTEM AND METHOD FOR CONTROLLING OFFSHORE FLOATING WIND TURBINE PLATFORMS - A method for controlling an inclination of a floating wind turbine platform comprising a generator, a set of turbine blades connected to a shaft inside a turbine nacelle, the turbine nacelle being mounted onto a tower, and at least three stabilizing columns is presented. Each of the at least three stabilizing columns have an internal volume for containing ballast. Position data associated with an orientation of the floating wind turbine is received. A heel angle in reference to the floating wind turbine platform is determined based on the position data. A first signal for adjusting at least one of a blade pitch of the set of turbine blades, and a torque of the generator is sent based on the determined heel angle. A second signal for distributing the ballast among the at least three stabilizing columns is also sent. The second signal for distributing the ballast is based on the determined heel angle and the first signal. | 11-20-2014 |
20140196654 | Floating Wind Turbine Platform with Ballast Control and Mooring System - A floating wind turbine platform includes stabilizing columns, a tower, water-entrapment plates connected to the stabilizing columns, and a ballast control system. The tower is mounted over one of the columns. The stabilizing columns include internal volumes for containing a ballast. The ballast control system includes an alignment sensor and a controller. The alignment sensor is configured to detect a rotation of the tower. The controller is configured to direct a transfer of ballast from one column to another column to adjust an alignment of the tower. | 07-17-2014 |
