Re: [PSUBS-MAILIST] Design depth

Jim,

I recommend you target 600 feet as your test depth, assuming you have such water depth available to you.  If you test to 400 feet, that would become your "rated" depth and you would still want to impose a safety margin.  If you assigned a safety margin of 2x for the rated depth it would put your maximum operating depth at 200 feet.

Hi, Alan,

 

In my mind I had picked up "design to twice the operating depth." I plan to test to 2/3 of the design depth (US Navy standard) which is the same thing as 133% of the operating depth.  Therefore:

 

Operating Depth    300'

Test Depth            400'

Design Depth        600'

 

Those numbers might change slightly during the design process, but the proportional relationships should stay the same.
