Abstract: A wind turbine tower includes a plurality of tower sections axially aligned and connected together. Each tower section includes an inner wall having a tapered cylindrical shape concentrically positioned within an outer wall having a tapered cylindrical shape. An annular space is defined between the inner wall and the outer wall, and a layer of concrete is disposed within the annular space. A plurality of post-tensioning cables extend longitudinally within the annular space or outside the outer wall, such that a first one of the tower sections is connected to a second one of the tower sections by a plurality of the post-tensioning cables.

Abstract: A hull for a semi-submersible wind turbine platform capable of floating on a body of water and supporting a wind turbine includes a keystone and at least three bottom beams extending radially outward of the keystone. Each bottom beam has a primary beam portion and a column base portion, wherein the column base portion is configured to support an outer column of the hull thereon, and wherein the primary beam portion defines a first ballast compartment therein. The first ballast compartment is in fluid communication with water in the body of water in which the hull is floating.

Abstract: A method of constructing and assembling a floating wind turbine platform includes constructing pre-stressed concrete sections of a floating wind turbine platform base, assembling the floating wind turbine platform base sections to form the base at a first location in a floating wind turbine platform assembly area, and moving the base to a second location in the floating wind turbine platform assembly area. Pre-stressed concrete sections of floating wind turbine platform columns are constructed, and the column sections are assembled to form a center column and a plurality of outer columns on the base to define a hull at the second location in the floating wind turbine platform assembly area. The hull is then moved to a third location in the floating wind turbine platform assembly area. Secondary structures are mounted on and within the hull, and the hull is moved to a fourth location in the floating wind turbine platform assembly area. A wind turbine tower is constructed on the center column, and a wind turbine is mounted on the wind turbine tower, thus defining the floating wind turbine platform. The floating wind turbine platform is then moved to a launch platform in a fifth location and launched into a body of water.

Abstract: A floating buoy includes a buoy hull having a tower that extends outwardly from the hull. A plurality of sensors are mounted either on the buoy hull, within the buoy hull, and/or on the tower. The plurality of sensors includes at least one met-ocean sensor, at least one ecological sensor, and at least one wind speed measurement sensor. The floating buoy further includes an autonomous power system that is configured to provide electrical power to each of the plurality of sensors. The wind speed measurement sensor may be a Light Detection and Ranging (LiDAR) wind speed measurement sensor, a surface level wind speed sensor, an ultrasonic wind speed sensor, or SODAR.
