Abstract: A tower base section, a tower adapter and a wind turbine having the tower base section and the tower adapter are provided. The tower base section includes a tubular side wall and a flange portion. The flange portion has an inner radius and an outer radius and is configured as a T-flange. The tubular side wall is located closer to the outer radius than to the inner radius. The adapter is arranged outside the tubular side wall and includes a bottom surface pressing from above on the flange portion.

Abstract: A self-supporting platform for a wind turbine tower comprises a grid structure having a plurality of grid nodes, wherein the grid structure transfers a load on the platform to the wall of the tower.

Abstract: A reinforcement assembly for use with a wind turbine. The wind turbine tower includes a first tower member that is coupled to a second tower member. The reinforcement assembly includes a first reinforcement member that is coupled to the first tower member. A second reinforcement member is coupled to the second tower member. A tension member is coupled between the first reinforcement member and the second reinforcement member. The tension member is configured to at least partially transfer a bending load from the first tower member to the second tower member.

Abstract: A tower is provided having a plurality of axial substantially tubular sections with an outer diameter no greater than a designated maximum diameter. At least one of the sections includes at least one reverse taper portion located near a base of the tower. The reverse taper portion has a first end, located near the base, having a first diameter. The reverse taper portion has a second end, opposed to the first end, having a second diameter. The first diameter is smaller than the second diameter.

Abstract: A tower having a plurality of axial sections is provided. The tower includes at least one lower axial section having a non-circular cross-section in at least a portion thereof. The lower axial section is located near a bottom of the tower. At least one upper axial section has a substantially circular cross-section in at least a portion thereof, and is located near a top of the tower. The tower has a cross-sectional profile that transitions from the non-circular cross-section to the substantially circular cross-section, and an outer diameter of the tower is less than a designated maximum diameter.
