[PSUBS-MAILIST] New submarine

["Carsten Standfuß "]

GL says 1,2 from work to test depth (for work depth over 300 m). 
  And 1,73 from work to destroy depth (for depth over 600 m.)
It says 2,0 from work to destroy depth if the water depth in the dive
area is deeper than the work depth.   

So question number one: is the bottom in the dive area deeper than 1000
M ? Yes SF = 2,0 No : SF 1,73

I think 1,25 ABS is from work to test depth not to destroy depth ? 

A large dome for 1000 its a issue himself.

What is a good safety rating on a 1000m sub in terms of design crush
depth or rated vs crush ratio? 
Thanks,

Bare ABS rules give you 1.25 over predicted failure.  1.5 - 2.0 is
common in actual practice.  For a 1000m hull a 2.0 SF would necessitate
a lot of extraneous material.  Perhaps take the service conditions into
account? (i.e. will 1000m dives will be typical or exceptional?).
