[PSUBS-MAILIST] Fw: Taurus sub

Wed Sep 7 03:41:13 EDT 2016

Tim, 
I like Hanks idea of finding a large cylinder with it's pressure resistant form.
You could possibly pick one up very cheaply.
Even though you are going ambient for the habitat, you can only equalise the 
pressure to one point in the water column.
So at 5ft high with a moon pool entrance, the top of the habitat would be at a 2.5 psi
internal pressure above ambient. Doesn't sound like much but if you multiply it out
it is 360 pounds per square ft. 
I am a fan of putting motors on these habitats, to make them easy to put in position
& relocate. I know this now sounds very much like a large ambient submarine, but
why not! With a little bit more effort, you could double as both.

> The BCIT habitat is designed as a 10ft long, 5ft wide, 5ft high box. This creates a 15,000 pound buoyant force resulting in a dry weight close to 20,000 pounds.  For me personally, low volume is the key to keeping it towable by my truck.  Under 10,000 pounds for sure, preferred somewhere around 6,000 pounds.  A cylinder 8ft long with 4ft dia might be okay.  At this point I am thinking about a habitat the size of a 3-man tent (but made of steel or fiberglass).  Ambient pressure internally means that not a lot of structure is required (inexpensive) and low volume means easy deployment. The other issue is where to worki on it.  I don't have sufficient shop space at this time, but hopefully soon.  My dream is not dead yet, just constantly postponed.

> How big are you thinking for a habitat.  Where would you put it?  can you plunk it down anywhere you like?  Heck I have seen big tanks on skids that could be modified in a weekend.  Give me some idea of max and min size and I will keep an eye out for one.  Actually I have a tank on skids you can have for free.  I got it to build a bigger sub but can't seem to pull the trigger.  The tank is 21 feet long 5 feet dia  on a skid 11\16 shell and 7\8 heads.

She worked (occasionally) in the North Sea (<350 meters depth) and was built to compete with the PC-16s from Perry, which were actually never used in the North Sea, but were kept busy in the Med, instead. In any case, Taurus's dry transfer hatch is enormous to accommodate some specific kind of valve and or valve manifold--the dry transfer chamber could be equalized or pressurized as occasion demanded. And she has a BUNCH of compensated batteries, very much like a Pisces (only arranged low and along the sides, rather than in the middle). She is, as you might imagine, a bit of a bus. And roomy? Oh my, yes.

If Hank's used sub valuation guideline applies then this one is worth $120,000 in dive ready condition.  However, it's a very larger "personal sub" so perhaps the guideline does not apply.  Overhauling the systems and ABS recertification would likely cost than that amount again.  Serious money required.  Pretty cool, though.
