The invention also concerns the assembly formed by the device and a calibration model, along with an assembly procedure that uses same.

A method for mounting and/or dismantling turbine components is provided. According to this method, a crane is fastened to a turbine casing half in the area of the joint, and at least one component such as for example a turbine blade is brought into its mounted position and/or is removed from its mounted position by means of the crane. For this purpose, the crane has a tower with a multiple section jib having a plurality of segments, thereby allowing the components to be positioned accurately for mounting/dismantling. The mobile crane is connected to the turbine casing half by means of an adapter. The adapter has a fastening pin which is held in place by means of an existing through-bore in the turbine casing half. For the purpose of mounting the mobile crane, the adapter has a baseplate. For rotational locking of the crane, a securing element is provided.

A device is suitable for inserting sealing pads into one of the sectors of a turbine stator of a turbine, wherein the turbine stator includes a plurality of sectors with adjacent side faces abutting each other and slots arranged opposite each other in the adjacent side faces of two successive sectors.

The device includes a support for supporting the sector; a robot arm with means for gripping the sealing pads, each predefined in accordance with the slot intended to receive it. The robot arm is configured to insert each predefined sealing pad into the slot intended to receive it of one of the side faces of the sector.

A control device controls sectors for the assembly of turbine stators of a turbine. Each turbine stator is formed of an assembly of sectors juxtaposed to one another, and each sector has a reference. The control device includes an automated system for identifying the sector with means for reading the sector reference, a database of the references of the sectors that form the turbine stators of the turbine, and means for associating the read reference of the sector with a determined turbine stator of the turbine.

An installation for pre-assembling the turbine stators of a turbine each formed of several juxtaposed sectors, includes: an input carriage for conveying sectors intended to form the turbine stators. Each sector includes side faces provided with slots and being associated with a given turbine stator; an output carriage having various trays, each associated with a turbine stator; an automated device for inserting sealing pads configured to interact with a sector conveyed by an automated convey pallet, comprising a robot arm for inserting sealing pads into the slots in a side face of the sector; and another robot arm for gripping a sector equipped with pads from a pallet and depositing it on the tray associated with the turbine stator to pre-assemble the turbine stator.

A fixture assembly including a first fixture portion; a second fixture portion that interfaces with the first fixture portion; and a bladder assembly mounted to the second fixture portion to face the first fixture portion. A method of manufacturing a fan blade includes inserting a blade body and a cover into a fixture; and deploying a bladder assembly within the fixture to press the cover into the blade body.

There is disclosed an alignment tool for positioning an impact liner panel on a fan casing. The alignment tool comprises an attachment portion for attaching to the fan casing, a support surface for receiving a shim, and a magnet to magnetically retain a shim on the support surface. There is also disclose a tool kit for manufacturing a fan casing having an alignment tool and a shim. There is also disclosed a method of positioning an impact liner panel on a fan casing. It comprises attaching an alignment tool to the fan casing, magnetically retaining a shim on a support surface of the alignment tool; and positioning the impact liner panel against an abutment surface of the shim.

A method for disassembling/assembling a gas turbine including a seal plate disposed on a first side of a rotor disc in an axial direction of the rotor disc, and a seal plate restraint part for restricting movement of the seal plate in a radial direction of the rotor disc. The method includes a seal-plate-restraint-state switching step of operating the seal plate restraint part from a second side in the axial direction via a clearance between a platform of a blade and a region of an outer peripheral surface of the rotor disc except a blade groove for receiving the blade to switch between a seal plate non-restraint state where the seal plate restraint part does not restrict movement of the seal plate in the radial direction and a seal plate restraint state where at least a part of the seal plate restraint part protrudes in the axial direction.

A dual motor system includes a first motor providing a lower speed range and a second motor providing a higher speed range, wherein the motors are coaxially arranged and aligned on and drive a common shaft, and a motor control system controlling the speed of the first motor and engaging the second motor as needed. The first motor is a variable speed motor providing a lower two-thirds of a full speed range, and the second motor is an induction motor providing the upper one-third in the form of one or more discrete fixed speeds. The system may include a transformer including a first winding tap which provides a first higher speed, and a second winding tap which provides a second higher speed. The system may also include a flow control system for automatically controlling the speed of the motors for particular applications, such as flow control in a pool.

The systems and methods for assembling and installing multiple wind turbines from a single vessel are provided. Generally, the different embodiments use wind turbine components on the vessel that include blades, a nacelle assembly having a rotating hub, and a tower. A Turbine Installation Gantry System (T.I.G.S.) embodiment uses a gantry system having a truss sub-structure and at least one bridge crane on the elevated vessel for assembling the wind turbine blades on board to the nacelle hub supported above the seabed. A Skidding Turbine Installation Crane (S.T.I.C.) embodiment has a rotatable crane mounted on a skidding pedestal or cantilever structure to provide full access to the vessel deck and the blades outboard of the vessel for assembling each of the blades with the assembled nacelle assembly outboard. A Turbine Assembly and Positioning System (T.A.P.S.) embodiment includes a handling system and a crane both mounted onto a skidding cantilever structure for fastening blades to an assembled tower section and nacelle hub suspended cantilevered outboard of the vessel by the handling system. A combination embodiment uses selected components and systems from the T.I.G.S., S.T.I.C. and T.A.P.S. embodiments to provide redundancy and simultaneous movements of components and systems.
