Figure F35. Plot of the results from successful attempt to unlatch the Motion Decoupled Hydraulic Delivery System (MDHDS) during Deployment 2, Site U1402. At approximately –220 s, the pump rate was increased to drive the penetrometer into the formation. As a result, the standpipe pressure increased and the shaft pressure recorded an abrupt increase (F). The pumps were turned off at G, and pressure dissipation began. Letters correspond to Table T11.
