Abstract
A high pressure intensifier system is disclosed. The system has a high pressure intensifier configured to receive hydraulic fluid from an input and provide the fluid to an output at a higher pressure than at the input, a monitor configured to monitor the pressure of hydraulic fluid provided at the output, and a control configured to control the supply of hydraulic fluid from the input, and configured to maintain the pressure of hydraulic fluid provided at the output at substantially a predetermined value.
Claims6
A high pressure intensifier system comprising:
- a high pressure intensifier configured to receive hydraulic fluid from an input and provide the fluid to an output at a higher pressure than at the input;
- a monitor configured to monitor the pressure of hydraulic fluid provided at the output;
- and
- a control configured to control the supply of hydraulic fluid to the input, and configured to maintain the pressure of hydraulic fluid provided at the output at substantially a predetermined value, wherein the control comprises an electronic control coupled with the monitor, and configured to compare the pressure of hydraulic fluid provided at the output with a predetermined value, the electronic control is provided in a subsea electronic module for a subsea well control system, and the electronic control is in communication with a control center via an umbilical;
- wherein the output is used to operate a downhole safety valve in a well fluid extraction flowline;
- and
- wherein the predetermined value may be changed by communicated messages from the control center via the umbilical to limit a pressure differential between the output and fluid in the flowline.
