Nahhhh thats the pull tab for the crotch dry zip

Errrrrr didnt Comex do 600m on a Mk15.5 without an exposure suit? Thats a lot of kit for an additional 10m

I believe COMEX did approx 520M in water and 630M in a chamber as part of the hydra project. I'm fairly positive that SSD equipment was used.

Comex have an impressive record of deep diving. Like the deepest sea dive connecting a pipe at 534m (Hydra 8, 1988) and a wet chamber dive to 701m (Hydra 10, 1992).

A documnet listing their different deeep diving operation:

I would be nice to get to know what sort of equipment the divers used for the 534m sea dive, umbilical OC, SCR or CCR?

In 1988 Comex extended hydrogen-helium-oxygen saturation diving to a storage depth of 1706 feet with excursions to 1742 feet (Hydra 8 I believe). The usual commercial limit today is 400msw, but there are exceptions. A number of different closed-circuit systems are used. It really depends upon the company you work for.

That is one cool rebreather

I see the specs say the viewing faceplate is 1.3" thick clear acrylic.

I have only one question - how much?

I thought there was something missing on the photo, one brave SOB to ride the dive stage without faceplate. Mind you with only 1.3 inches no wonder its hidden. Enclosed jpehg of a British 10 incher... now thats a real viewport. Lol iain

Umm. I haven't read this in too much detail but isn't this at atmospheric pressure? So not really a dive as we'd know it, but more like a ride in a submarine - and the bonus of no deco!!!!

That IS one big Muvva piece of cast 'optical glass'. !!! ;-)
But it looks more like a circumfrential viewport or an axial hull section that
they intend to finish to about 3 in. thick, rather than a 'faceplate'. The pressure / load distribution is a bit different. Still, I wouldn't want it dropped on my toe.

Nice post thanks for bringing it up. Your right it was a cast arcylic forward hatch view dome aft support ring. After moulding but before final finish and polishing for a 1000FSW sub project I was involved with. After polishing you were not allowed near it for fear of scratching it, A spanner (US crescent wrench ) in your pocket was a no no.

While for some on the forum these Atmospheric Diving Suits (ADS) projects might not fulfill there idea of diving equipment. The emergency part of our design project required for a 72 hour rebreather to fulfill ABS (American Bureau of Shipping) "Classification for Submersibles and Diving Systems"
I would submit this to be both diving and rebreathers and therefore valid to the forum.

Jay Shepcot, ADS pilot, Date: August 29th 1999 Depth 972 FSW

The dive crew was working from a semi-submersible (a jack up drilling rig) with an air gap of approximately 100 feet (above sea level). As the ADS was being recovered, a piece of lifting tackle gave away and the ADS dropped to the end of a safety cable. The shock load swung the ADS up beneath the semi-sub where it hit and broke one arm off the suit before the safety cable was severed by the edge of the deck. The ADS fell into the sea and because of the missing arm flooded and sank to the pontoon. It is believed that the diver died of a broken neck
which occurred at the same time the arm was broken off. Once submerged, the suit flooded. Two standby dives were made before the diver was located and brought to the surface.
