Fusible plug fire gas safety control system applied to offshore oilfield and floating production storage and offloading (FPSO)

Abstract

The invention discloses a fusible plug fire gas safety control system applied to an offshore oilfield and a floating production storage and offloading (FPSO). The fusible plug fire gas safety controlsystem comprises an air source voltage regulating system, an urgent shutoff station control system; a fusible plug control system and an on-line testing system. Bypass hand-pull valves are configuredto realize the on-line maintenance and automatic switch of the fusible plug fire gas safety control system; a testing loop is arranged to realize the on-line testing of the fusible plug fire gas safety control system; an urgent shutoff station is configured to realize manual opening of a deluge valve; and a self-operated type filter voltage regulating valve is configured to realize automatic accurate regulation of control pressure. The fusible plug fire gas safety control system applied to the offshore oilfield and the FPSO solves an actual technology problem of a fusible plug control panel ofthe offshore oilfield, and maintainability and reliability of the system are further improved. The fusible plug fire gas safety control system applied to the offshore oilfield and the FPSO meets therequirements of development and production of the offshore oilfield.

Description

technical field [0001] The invention relates to an oil field fire and gas safety control system, in particular to a fusible plug fire and gas safety control system applied to offshore oil fields and FPSOs. Background technique [0002] Fusible plug fire and gas safety control system is an important equipment for the safe production of offshore oil platforms and FPSO (floating oil storage vessels). Production provides an important guarantee. [0003] At present, the fusible plug fire and gas safety control system is widely used in offshore oil platforms and FPSOs. However, through the actual application feedback on the spot, the original fusible plug fire and gas safety control system is inconvenient in maintenance and testing. At the same time, the early design is basically It is a manual valve control, and it is impossible to realize automatic real-time switching of the system. Therefore, a fusible plug fire and gas safety control system applied to offshore oilfields and F...

Problems solved by technology

[0003] At present, the fusible plug fire and gas safety control system is widely used in offshore oil platforms and FPSOs. However, through the feedback from the actual application on site, the original fusible plug fire and gas safety control system is inconvenient in maintenance and testing. At the same time, the early design is basically It is a manual valve control, and it is impossible to realize automatic real-time switching of the system. Therefore, a fusible plug fire and gas safety control system applied to offshore oil fields and FPSO is especially needed to solve the actual technical problems of fusible plug control panels in offshore oil fields.
