Provided is a dismantling method of a tower-type wind power generation system in which scaffolding is not required around a tower body. After climbing on a work bench set outside an outer wall of a tower body and removing a lower end part of an upward-tapering part in an upper end part of the tower body over the entire periphery of the tower body, the tower body is sequentially removed from an uppermost part of a cylindrical part of the tower body below the upward-tapering part to gradually dismantle the tower body from the top. The remaining upward-tapering part of the tower body from which the lower end part is dismantled first is supported by a jack provided in an inner column while being lowered, along with the dismantling, into an internal cavity of the cylindrical part of the tower body below the upward-tapering part and is placed on a placement protrusion provided on an inner wall of the tower body. In a case where a low inner column is set, the inner column is suspended from the remaining upward-tapering part, a lower end part thereof is removed, and then the inner column is lowered on the ground in the tower.

A connection system for joining two wind turbine components together includes one or more bearing surfaces and one or more support surfaces extending away from the one or more bearing surfaces on a first wind turbine component, and one or more bearing surfaces and one or more support surfaces extending away from the one or more bearing surfaces on a second wind turbine component. One or more bores are formed in the one or more support surfaces of the first and second wind turbine components. One or more pins are configured to be engaged with respective one or more bores of the first and second wind turbine components to thereby join the two components together. A method for joining two wind turbine components together is also disclosed.

This invention relates to a method of manufacturing a bulkhead unit, a method of installing a bulkhead unit, a bulkhead, a bulkhead unit and a wind turbine blade. The bulkhead is manufactured by vacuum forming or rotational moulding and has a set of predetermined openings formed during manufacturing. Various additional elements are pre-mounted or pre-integrated into the bulkhead before installation of the bulkhead unit. This pre-assembled unit can then be positioned inside the blade root section and connected to the blade section.

A disassembled wind turbine under repair includes a tower secured to a foundation and a nacelle mounted atop the tower. The nacelle includes a base wall, side walls, a front wall, a rear wall, and a top wall. The front wall includes an opening configured to receive a main shaft of the wind turbine; however, the main shaft and a rotor of the wind turbine have been removed from the nacelle during a repair procedure. As such, the disassembled wind turbine further includes an external platform assembly secured at the opening of the front wall of the nacelle during the repair procedure.

A method for balancing segmented rotor blades for a wind turbine may include determining a weight for each of a plurality of blade segments, wherein each blade segment extends between a first end and a second and is configured to form a common spanwise section of a segmented rotor blade between the first and second ends. The method may also include determining an initial static moment for each blade segment based on the weight of the blade segment, wherein the initial static moment of at least one of the blade segments differing from the initial static moments of the remainder of the blade segments. Additionally, the method may include adding mass to each of the blade segments to increase the initial static moment for each blade segment to a predetermined static moment, wherein the predetermined static moment is greater than each of the initial static moments of the blade segments.

Provided is a wind turbine with a nacelle including a mounting structure to which at least one facing element is attached and/or with a hub including a mounting structure to which at least one facing element is attached, which at least one facing element is attached with several fixation devices, whereby each fixation device includes a bolt with a bolt head at one end, a threaded shaft extending through an opening in the facing element and the mounting structure and a tool mount for attaching a tool for holding the bolt, and a nut screwed on the threaded shaft, with the bolt head positioned at the outside of the nacelle or the hub and the tool mount and nut positioned at the inside of the nacelle or the hub.

According to some embodiments, a system may include an additive manufacturing platform that provides additive manufacturing capability data. A customer platform, associated with a customer, may transmit an industrial asset item request for an industrial asset item. A digital transaction engine may receive the additive manufacturing capability data and the industrial asset item request. The digital transaction engine may then associate the industrial asset item request with an industrial asset definition file, and, based on the additive manufacturing capability data and the industrial asset definition file, assign the industrial asset item request to the additive manufacturing platform. The assignment of the industrial asset item request may be recorded via a secure, distributed transaction ledger. Responsive to the assignment, the additive manufacturing platform may create the industrial asset item (e.g., via an additive manufacturing printer) and provide the item to the customer.
