                      Bobber Failure Modes
                      from P.Tillier manual


    Delta-P fails		pumps constant volume of oil

    T  fails     		0   Max P

    P  fails   			0    T   = (Tmin + Tmax)/2 in 1/100 C

    A/D fails    		0    0


    Actual cases from  Subduction and NATRE:

       sb17     T=> 400 (max)  P varies in same range as before (~100)

       sb18     T=0    P=400 (max)  This is T failure.

       sb21  a) P=0    T varies near 500
             b) P=400 (max)    T=560

       tr60     P=0    T ranges from 220 to 300, then gets larger
                       quickly - leveling off near 560 ?

       tr62     P=274  T=560 (max is 550)
