Hello unnammed stranger,
A normal ballast system have 2 systems (like yours)
exept that one system is ambient (for surface) and the other system is 1atm
(trim) so, as you said, the boyancy won't change as you go deeper.
When I look at your system I don't see why you
devide your 2 systems since they will work the same way. I think it would work
the same if you only had 1 ambient system.
I also don't see how it could be simplier for the
piping.

I was waiting for a fist fight at the end of this pissing contest then we can all hose the testosterone off the decks and go on eh. I'm just a newbie so don't mind my little joke. I did have some ques regarding a new design I am trying to come up with to minimize exterior piping and make lines and valving simpler inside the hull. my trim tanks will be a closed sys and I am not sure if this is necicary or not. I was concerned with the air in my trim tanks loosing mass as I drive deeper if I leave them ambiant which would cause my sub to become neg boyant at depth. The other concern is that if the trim tanks are a closed sys is the wall seperating the main tanks from the trim tanks need to be reinforced? as for the other ques that I have had earlier I found a place I should have known to look for affordable parts and sealed rotating assemblies. grainger.com has ! a wide variety of parts for those interested in looking. they also have a few co2 and o2 meters avalible and a wide variety of hydrolic as well as peunamatic parts for fabrication.
any thoughts on rectangular port view holes instead of round.
