I saw 2 different news reports that had diving experts. One was a PADI MSDT
from Massachusetts and the other was the captain of the Seeker.
The latest Navy manual allows up to 30 minutes at 270' on surface supplied
heliox 14/86 with 152 minutes of deco (switch to 40/60 at 100 ft and O2 at
50 ft). The majority of the deco is done at 40 ft in a chamber on O2.
Longer bottom exposures are permitted in extreme circumstances ("extreme
exposure"). Saturation diving is possible but requires extensive support
personnel and equipment. The manual calls for a constant flow helmet for
depths up to 300 ft and a helmet with a demand regulator for dives deeper
than 300 ft or saturation dives.
Maybe someone who really knows will tell us how they'll do this. The
"experts' said that saturation was the only way.
