In the sim, I'm not having any problems at all running deep and long at least once every three days or so, just to rest my crews.
Any replies on this would be appreciated, thanks.
I did a forum search on this topic and found some interesting threads, but no definitive answers. I have noticed, however that the oxygen level doesn't drop immediately but after a few hours. A bit confusing but sure not a game killer. I'm enjoying what I'm doing now very much, but as for ultimate realism, I just don't know.

Close the lid, and the creww starts to use up the oxygen in the boat. They keep using it up as long as the boat remains submerged. It does not regenerate at all, ever. But when the oxygen level drops to 17% (from the normal 21%) the LI will begin to vent oxygen into the boat from cylinders of compressed oxygen that the boat carries. These cylinders have a limited capacity. Their contents are shown on the oxygen gauge (natch) which comes with the h.sie patches. Normally, there is enough oxygen in the boat for about 8 hours of submerged operation before the tanks have to be used. In the h.sie patch, how fast the oxygen is consumed depends on the crew's activity - keep them at Silent Running and they will use as little as possible. But once the oxygen is down to 17%, they have to have more, and that means venting from the oxygen tanks. Once the tanks are emptied....
There is no way to refill the oxygen tanks, except to return to a port and replenish. You can not refill while under way. When the tanks are empty, they stay that way until you return to port. Submarines did not carry the equipment necessary to extract oxygen from the air and store it.
The oxygen in the air in the
boat is a different story. Once you return to the surface and the hatches are opened, the oxygen is quickly replaced by exchange with the outside air. Takes a couple of minutes. Then you can dive again, but only until the oxygen level goes down to 17%. At that point, the crew has to get more oxygen, either from the tanks or from the atmosphere.
AFAIK, neither the h.sie nor the Stiebler patches has any effect on CO2 accumulation. A search of the documentation for both does not find any reference to "CO2" or "carbon dioxide", except to state that the new oxygen gauge replaces the CO2 gauge.
