摘要:
A wind turbine platform is configured for floating in a body of water and includes a hull defining a hull cavity therein. The hull is formed from reinforced concrete. A tower is configured to mount a wind turbine and is also connected to the hull. An anchor member is connected to the hull and to the seabed.

A method of forming a hollow composite construction member of the type suitable for use as building material includes providing an elongated inflatable mold assembly having a longitudinal axis, a flexible tubular bladder wall defining an elongated inflatable cavity, a reinforcing fabric positioned concentrically around the flexible bladder wall, and a flexible air-impervious outer layer positioned concentrically around the fabric. The bladder wall and the outer layer define an elongated annular space with the fabric positioned therein. Tension is applied longitudinally to the fabric and fluid is introduced, into the cavity to at least partially inflate the mold and shape the fabric. The mold is shaped to a desired shape while maintaining the fabric under tension. The elongated annular space and the fabric are infused with a rigidification material. The rigidification material is hardened while maintaining the fabric in tension to form a rigid hollow composite construction member.
摘要:
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.
摘要:
A semi-submersible wind turbine platform is capable of floating on a body of water and supporting a wind turbine, and includes a keystone. At least three bottom beams extend radially outward of the keystone, and a center column extends perpendicularly from an upper surface of the keystone, a first axial end of the center column attached to the keystone; the center column configured to have a tower attached to a second axial end thereof. One of a plurality of outer columns ex-tends perpendicularly from an upper surface of each bottom beam, wherein first axial ends of the outer columns are attached to a distal end of each bottom beam. One of a plurality of top beams extends between a second axial end of each outer column and a second axial end of the center column, wherein the top beams are configured substantially not to resist bending moment of a tower attached to the center column.
