The TBM is used to drill a 5 km tunnel connecting Tuen Mun to the Hong Kong International Airport. The machine has a diameter of 17.6 m, 0.2 m more than Bertha, the previous largest tunnel boring machine.[1][2]

The machine will excavate a 5 km-long underwater tunnel, working at pressures as high as 5 bars. The drilling will take place in depths of up to 50 m below sea level.[3]
