System 1 Beam Drilling
A new ‘top down working’ technique reduces operative risks by enabling gas-free maintenance without the need to send personnel into the excavation. The system employs a weighted beam to provide controlled downward force to create the gas-tight seal between the drilling base and the top of the main.
