Tunnel Boring Machine (TBM) Transfer Shuttles


SMP have recently been contracted to build TBM Personnel Transfer Shuttles for a major tunnelling project.

Transfer Shuttles are used for transferring compressed air workers/divers from the air locks of the TBM to the main decompression complex. The Shuttle is designed to accommodate 2 men in the entry lock and 6 men in the main lock.

The Life Support System is designed to provide two (2) hours of life support when it is disconnected from the TBM or decompression complex. The chamber is installed in a crash proof exostructure with interconnecting chamber mating clamp mounted on the end of the structure. These units are mounted on wheels so that they can be transported easily during a working transit period.
