Re: [PSUBS-MAILIST] Reserve buoyancy

Thanks for the kind words on psubs. I appreciate it.
 
I was looking at the wreck photos again and wondered about visibility from the sub. Can you actually see the side thrusters from the small ports, and is the aft thruster visible from the dome? There don't seem to be many nets hung on the garibaldi, but I remembered that Delta got hung up on the Lusitania. They can jettison the stern section of their main ballast tank, including the prop and rudder, so freed themselves. KSS can't do that. It is something to think about as a safety feature for future subs, and perhaps for retro fit on KSS.
 
Let me say again how much I admire this sub and all your work with Carsten. With your previous experience, it seems that you have been able to work the bugs out in the design phase so that KSS was just as nearly perfect as Carsten predicted. That has to feel good.

Hi Vance,
 
Some pictures on a Croatian news page. You can see the axe bow of the capsized ship!

can be translated by google.
 I have a lot of pic’s  but I have to ask because its intellectual property.
 
The main reason for having battery’s in a separate compatiment is safety. For the Eurosub we choose good quality AGM battery’s which are unlikely to explode.
The 7,2 Kw/h proved enough for whole day diving. This was without long surface transit.

Is the Garibaldi Expedition web page off line for more sub pics (I hope)?

Or a keel box or radially bisected pod open to the hull (sealed inside with a lid) like the old PC-5 or the Nekton series. That would provide a separate compartment for the batteries but do away with the leak problem completely. I don't have the engineering expertise to calculate such a thing, but ABS bought off on those boats, so one must assume that it can be done. PC-5 has a 20" tube section with one small hatch forward to pull batteries through (an enormous pain in the butt, according to the guys who worked on it). The nektons have an aluminum box top, o-ring sealed that screws down to the projecting edges of the steel box keel, which exposes the eight batteries from one end to the other (harder to build but easier to maintain).
 
What do you think, Carsten? A 1.2m X 30 cm X 30 cm box in the Eurosub? Or a 50 cm OD tube section? Now that KSS has been out to work, do you think it is necessary, or does she have enough power already?

Rootssub?
 
Make one central Pod under the pressure hull. 
If it flood it increase the MG stability 
and maybe partly compensate the FSEffect..
