<DIV><FONT size=3>The cost of pressure testing has as much to do with 
multi-point measuring and analysis of distortion as it does with just

[above crush depth] at which the vessel undergoes enough stress that one

        <DIV dir=ltr>Hi Hank, 
        <DIV><BR></DIV>
        <DIV>I asked at Carderock over a decade ago and was told the cost would 
        depend on setup time, which varies depending on how much instrumentation 
        you want during the test, but that a typical figure was around $27K. 
        Waaaay beyond my budget. Dale Heinzing tested Snoopy somewhere on the 
        West side of Canada at a lumber yard. Snoopy went in the tank alongside 
        the lumber and must have been pretty well disinfected, but the scary bit 
        was that they released the pressure almost instantaneously, with a bang. 
        That test was  to only 400' so not really sufficient for a Nekton, 
        but it might still be of interest since I think it's relatively close to 
        you and probably was inexpensive.</DIV>
