RE: [PSUBS-MAILIST] update Kreidesee

Cliff, (and other interested)

There is now a page with technical date and description.

http://www.airesearch.nl/index_bestanden/Page746.htm

leaves some of your questions open.

-one person can be compensated with the VBT. But for a long, deep mission with 2 persons, you can take extra battery’s Soda lime etc. with you

-However built by standards of ABS /GL , no certification is planned It is sold as a “submarine building kit”

-reserve buoyancy is about 150 Kg

Excellent progress on Kreideseesub (what does this name translate into in English)! Nice design. Can you tell us some design specifications. I can't read German but it looks like the design depth is 250 km. Is this correct. With the design being for 2 or 3 persons, how are you going to handle the ballast difference between 1, 2 or 3 persons, +/- 70 kg per person, i.e., removable fixed ballast or extra large variable ballast tank? What is the hull made out of? Are you going to design for extended dives with CO2 scrubbing and O2 makeup? What is the main propulsion bus voltage? Are you planning on classing the boat? How do you plan to launch and retrieve the boat? What is the displacement and reserve of buoyancy?

Keep up the pictures.

Hi,

The last 2 week I did 90% of Kreideseesub hull.

A professional welder did the welding.
