Definitions

  • a method may include charging an accumulator to a base control system pressure; and/or stroking a supercharge cylinder to increase accumulator pressure above the base control system pressure to an increased system pressure.
  • FIGURE 4 is a schematic illustrating a system configured to stroke the supercharge cylinder to fill with new fluid according to one embodiment of the disclosure.
  • valves 102, 104, and 106 may be opened or closed to operate the subsea system 100 along with the supercharge control valve 112.
  • pressure may be directed into the supercharge cylinder 114 to move the piston 116 upward in the cylinder 114.
  • FIGURE 3 is a system configured to stroke the supercharge cylinder 114 according to one embodiment of the disclosure.
  • the supercharge control valve 112 may open to allow the pressure 202 to propagate to pressure 302 to the supercharge cylinder 114 and advance the piston 116 in the cylinder 114.
  • the valve 106 may be open such that as the piston 116 advances upward, pressure is increased in the fluid above a bottom surface of the piston 116.
  • the increased pressure in the cylinder 114 may result in increased pressure 304 in the hydraulic lines of the subsea system.
  • the valve 104 may be closed to prevent exit of pressure from the input of the supercharge cylinder 114 forcing the increased pressure to the accumulators 118.
  • the accumulators 118 and other subsea equipment may operate at a pressure above base control system pressure.
  • multiple superchargers 114 or accumulators 118 may be configured to achieve fixed steps in the increased base control system pressure, such as 5000, 7500, and 10000 psi.
  • a single accumulator may be charged and regulated to provide the fixed steps in the increased base control system pressure.
  • FIGURE 5 is a flow chart illustrating one method of supercharging a hydraulic system according to one embodiment of the disclosure.
  • Increased pressure in a hydraulic system may be achieved through the method 500, which begins at block 502 with charging accumulators to a base control system pressure.
  • a supercharge cylinder is stroked to increase accumulator pressure above a base control system pressure.
  • the supercharge cylinder is stroked in to fill a supercharge chamber of the supercharge cylinder with new fluid. Operation of a system with a supercharger cylinder as described in blocks 502, 504, and 506 are generally described with respect to a particular system shown in FIGURE 2, FIGURE 3, and FIGURE 4.
  • the deintensifier 612 may provide an output pressure to the sensor 632 at a fixed ratio or fixed offset from the pressure in the line coupled to the accumulator 118, which allows the pressure sensor 632 to be a low pressure sensor 632.
  • a pressure readout 616 and an isolation valve 614 may also be coupled to the pressure sensor 632 to allow a manual readout of the pressure.
  • the pressure sensor 632 and related components 622 may be located in a first module, such as a module on a the surface at a ship or drilling rig.
  • the supercharge cylinder 114 and related components 620 may be located subsea, such as near a blowout preventer (BOP). In another embodiment, the components 622 may be located subsea, such as near the blowout preventer (BOP).
  • FIGURE 9 is a graph illustrating increased pressure obtained at an end of a ram with another supercharged pressure according to one embodiment of the disclosure.
  • Lines 906 and 908 illustrate an initial pressure obtained of 10000 psi that may allow shearing of drill pipe corresponding to the pressure 828.
  • Disk and disc includes compact discs (CD), laser discs, optical discs, digital versatile discs (DVD), floppy disks and blu-ray discs. Generally, disks reproduce data magnetically, and discs reproduce data optically. Combinations of the above should also be included within the scope of computer-readable media.
  • instructions and/or data may be provided as signals on transmission media included in a communication apparatus.
  • a communication apparatus may include a transceiver having signals indicative of instructions and data. The instructions and data are configured to cause one or more processors to implement the functions outlined in the claims.
