  • Heave Compensated Snubbing System and Method
    Publication number: 20090000788
    Abstract: A heave compensation system that facilitates the transfer of pipe between a floating platform and a snubbing jack. The heave compensation system includes a first end connected to the floating platform and a second end in connection with a traveling slip assembly of the snubbing jack, the heave compensation system is operable between a disengaged position and an engaged position. When the heave compensation system is in the disengaged position the traveling slip assembly moves separate and independent from the movement of the floating platform, and when the heave compensation system is in the engaged position the traveling slip assembly is locked in a constant position relative to the floating platform.

  • Pulse frequency modulation drive circuit for piezoelectric transformer
    Patent number: 6016052
    Abstract: A pulse frequency modulation drive circuit (1114) for a piezoelectric transformer (1102) is provided. Circuit (1114) includes a piezoelectric transformer (1102) having a resonant frequency and an input and an output section. A frequency feedback network connected to the piezoelectric transformer (1102) and an output level sense (1112) connected to the piezoelectric transformer (1102) is also provided. A drive circuit (1114) has a first switch (S.sub.1) and a third switch (S.sub.3) having a capacitance (1118) therebetween. A second switch (S.sub.2) and a fourth switch (S.sub.4) connect a supply voltage (V.sub.IN) to each of a pair of inductors (L.sub.1 and L.sub.2) and the second switch (S.sub.2) and the fourth switch (S.sub.4) are driven 180.degree. out of phase at the resonant frequency of the piezoelectric transformer (1102).
