Diving and Compressed Air Works at TBM Construction Sites

Below a depth of 40 metres (which equals 4.0 bars over pressure) workers enter a zone where it is no longer effective to carry out compressed air work under conventional conditions. However, because the next generation of tunnels will be longer and deeper than anything we have at present, it can only be a matter of time and opportunity before divers start playing a key role in hyperbaric work.
