Abstract: An assembly and method are provided for preventing exposure of personnel to an opening defined by a surface of a wind turbine. Accordingly, a hatch assembly is arranged adjacent to the opening. The hatch assembly includes a frame structure and a support structure. The frame structure includes a plurality of frame members arranged together to at least partially surrounded opening the plurality of frame members further define a passageway for receiving the support surface. The support surface is slidable between a first position and a second position. The support surface occludes the opening defined by the surface of the wind turbine when the support surface is in the first position and occludes the passageway defined by the plurality frame members when in the second position so as to prevent exposure of personnel to the opening.

Abstract: A tower assembly for a wind turbine includes a tower and a freestanding internal tower structure assembly. The tower has a tower wall defining an inner surface and an outer surface separated by a tower wall thickness, with the inner surface defining a tower interior. The internal tower structure assembly is positioned within the tower interior. The tower structure assembly includes a plurality of stackable support structures configured to support one or more internal tower components. Further, the tower structure assembly is freestanding within the tower interior.

Abstract: The present disclosure is directed to a ladder attachment system for securing a ladder within a tower of a wind turbine. The ladder has parallel legs and a plurality of rungs arranged perpendicularly between the parallel legs. The ladder attachment system includes at least one external stiffener configured at a top end of each of the parallel legs. Each of the external stiffeners includes a longitudinal body having an open cross-section configured to receive one of the parallel legs along a length thereof. Further, the ladder attachment system also includes a load-bearing bracket assembly configured with each of the external stiffeners. In addition, the ladder attachment system includes at least one support arm arranged in a horizontal plane and configured with each of the parallel legs, with the support arms being spaced apart from the load-bearing bracket assembly along a height of the ladder.

Abstract: An enclosure associated with a wind turbine tower includes a plurality of pre-assembled sections configured to be attached to a section of the wind turbine tower. The plurality of pre-assembled sections form an enclosure around the section. The enclosure is configured for storage of electrical components associated with a wind turbine. The enclosure is also configured to increase available space within the wind turbine tower by storage of the electrical components in the enclosure.

Abstract: A method of assembling a fuel delivery system is provided. The method includes providing a base that includes a surface, a receptacle extending into the base from the surface along a longitudinal axis, and a plurality of channels extending into the base from the receptacle. Each of the plurality of channels includes an inlet end and an outlet end, and each of the plurality of channels intersects the receptacle at the outlet end, wherein the receptacle and the plurality of channels are formed integrally within the base such that the plurality of outlet ends are spaced axially from one another. The method further includes securing a fuel nozzle within the receptacle, the fuel nozzle including a plurality of separate flow paths, wherein each of the plurality of channels is in flow communication with one of the plurality of separate flow paths.
