Currently, preliminary alignment of the shafting lines has been completed.
In order to start alignment of the wheel space using laser equipment, the rotors were removed from the bearing assembly bushings and installed in the shipping supports.
Necessary measurements of equipment parameters are carried out. A measurement report has been made and two high-pressure valves have been inspected.
Elements of the wheel space (diaphragm, seal boxes, inner cylinders) have been shipped to the installation area. The generator stator rotor weighting approximately 100 tons is being prepared for installation, and its de-preservation is in progress.
According to the installation schedule, the device for wheel space laser alignment will be delivered to the site in mid May.
