Checking the shaft alignment between the turbine and connected components, such as generators or pumps.

The process of inspecting and measuring the relative position of a turbine shaft and its associated drive components or loads to ensure proper mechanical alignment. This process is performed using precision measuring instruments such as dial indicators or laser alignment tools to detect horizontal and vertical misalignments.

The goal is to prevent bearing wear, excessive vibration, and overheating, while maintaining the turbine's efficiency and service life. Following the measurements, position adjustments and re-verification are performed to ensure optimal alignment before the turbine is returned to service.
