Abstract: A system and method are provided for manufacturing a tower structure. Accordingly, an interlocking form ring is additively manufactured with a first printhead assembly. The interlocking form ring defines a plurality of recesses in a radially inner or a radially outer face. A cementitious material is deposited within one or more of the recesses with a second printhead assembly. At least one reinforcing member is positioned within the recess with the second printhead assembly. The second printhead assembly is positioned adjacent to the cementitious material during the curing thereof so as to provide a slip form for the curing of the cementitious material.

Abstract: An additive printing device and a method for using the same to manufacture a tower structure of a wind turbine is provided. The additive printing device includes a vertical support structure, a support ring suspended from the vertical support structure, and a printer head movably coupled to the support ring for selectively depositing cementitious material. A drive mechanism, such as a rack and pinion, moves the printer head around the support ring while selectively depositing cementitious material. The vertical support structure may be raised and/or the relative position between the vertical support structure and the printer head may be adjusted to raise the printer head to print subsequent layers. This process may be repeated to print the tower structure layer-by-layer from the ground up.

Abstract: A wind turbine system includes a wind turbine generator having a rotor and a nacelle mounted atop a tower structure. The tower structure is mounted to a foundation structure and includes a plurality of tower sections, each including one or more tower section flanges. The wind turbine system further includes one or more connector rings. Each of the one or more connector rings is disposed proximate two adjacent tower section flanges and includes a plurality of pad eye adaptors each having an opening formed therein. The wind turbine system further includes a plurality of tensioned cables, with each coupled to one of the pad eye adaptors at a first end and the foundation structure at a second end. The plurality of tensioned cables are coupled to the tower structure at different or multiple connector ring heights based on site conditions to yield the desired lateral stability.

Abstract: A method and system including a circumferential seal assembly for sealing between components within a turbine is provided. A circumferential seal assembly is disposed in a slot extending circumferentially about an inner barrel. The seal assembly includes a first shim layer and at least one additional shim layer configured in an overlapping stacked configuration so as to stagger the end portions of each of the shim segments defined by the shim layers, relative to one another and circumferentially about the seal assembly. One or more cloth layers are configured wrapping about the first shim layer and the at least one additional shim layer to define a sealing member having a first sealing surface and a second sealing surface. The assembly further including a base plate, wherein the sealing member is disposed on an upper surface of the base plate to provide for sealing engagement between the components of the turbine.

Abstract: A gas lift valve assembly includes a housing and a check valve. The housing defines an inlet port and an outlet port, and includes an inner casing having a radial outer surface and a radial inner surface at least partially defining a main flow passage. The check valve includes a sealing mechanism disposed around the radial outer surface of the inner casing, and a valve member including an outwardly extending sealing segment. The valve member is moveable between an open position and a closed position in which the sealing segment sealingly engages the sealing mechanism.

Abstract: A gas lift valve assembly includes a housing, a check valve, and a fluid flow barrier. The housing defines an inlet port, an outlet port, and a main flow passage providing fluid communication between the inlet port and the outlet port. The main flow passage has an upstream end and a downstream end. The check valve includes a sealing element disposed at the downstream end of the main flow passage, and a valve member configured to sealingly engage the sealing element. The valve member is movable between an open position in which fluid flow is permitted in a downstream direction, and a closed position in which the valve member inhibits fluid flow in an upstream direction. The fluid flow barrier is disposed within the main flow passage, and is configured to direct fluid flow away from the sealing element when the valve member is in the open position.
