• Site installation: rigging and lifting coordination, laser alignment to better than 0.2 mm total run-out, correct shimming of drive motors.
• Commissioning: monitor vibration and bearing temperatures over the post-start monitoring period (target below 3.0 mm/s; white metal bearing operating range 50–65°C) and contribute to signed-off

commissioning reports.
