Abstract

A system for protecting piping downstream of a wellhead includes an inlet connected to the wellhead and an outlet connected to downstream piping. Two sets of series-connected surface safety valves are in a parallel fluid flow relation to each other and in fluid communication with the inlet. Two vent control valves, which are in fluid communication with each other, each of the two series-connected safety valves and the inlet and outlet of the system, are intermediately connected to the safety valves. Each vent control valve is in fluid communication with a vent line for venting process pressure between surface safety valves through the outlet control valve based on a signal-generating safety logic solver having preprogrammed safety and operational protocols and pressure sensing transmitters attached upstream of the outlet control valve Independent, tight shut-off tests of each series-connected surface safety valve set closes all valves upon electrical or hydraulic failure.

Claims (26)

1. A high integrity protection system (HIPS) for testing the protection and pressure control of a piping system connected to a wellhead, the HIPS having an inlet connected to the wellhead and an outlet connected to the piping system, the protection system comprising:

two sets of surface safety valves (SSVs) in fluid communication with the inlet, the two sets being in parallel fluid flow relation to each other, each set of SSVs consisting of two SSVs in series, either one or both of the two sets of SSVs operable as a flowpath for fluids entering the inlet and passing through the HIPS outlet for the piping system;

two vent control valves (VCVs), each of which is connected to piping intermediate each of the two sets of SSVs, each of the VCVs being in fluid communication with a vent line, whereby, upon opening of a VCV, process pressure between the two SSVs is vented;
and a safety logic solver in communication with the SSVs and the VCVs, the safety logic solver generating signals to control the operation of the SSVs and VCVs.
2. The HIPS of claim 1, further comprising:

pressure sensing transmitters for measuring and transmitting pressure on a section of piping upstream of the HIPS outlet.
3. The HIPS of claim 2, which includes three pressure sensing transmitters and the logic solver is programmed to transmit a signal to close the SSVs upon an increase in pressure above a threshold value transmitted by at least two of the three pressure sensors.
4. The HIPS of claim 1, wherein each of the two VCVs are connected to a conduit that is in fluid communication with a common vent line.
5. The HIPS of claim 1, wherein each set of SSVs are operable independently of the operation of the parallel set of SSVs.
6. The HIPS of claim 1 that includes pressure sensing transmitters positioned between the SSVs for measuring the pressure between the SSVs in each of the two sets of SSVs.
7. The HIPS of claim 1, wherein the safety logic solver is programmed to maintain one set of the SSVs in an open position when the parallel set of SSVs is moved to a closed position from an open position during a full-stroke test.
8. The HIPS of claim 1, wherein the safety logic solver is programmed to measure and record the response of each SSV during a full-stoke test.
9. The HIPS of claim 1, wherein the safety logic solver is programmed to measure and record the line pressure between the closed SSVs during a tight shut-off test, and to open the VCV
between the closed SSVs for a short period of time during the test to relieve the line pressure.
10. The HIPS of claim 8, wherein the safety logic solver is programmed to generate a failure signal if the pressure response of one of SSVs tested exceeds acceptable limits.
11. The HIPS of claim 8, wherein the safety logic solver is programmed to generate a failure signal during the tight shut-off test period if the pressure between the closed SSVs rises above a predetermined threshold value following closing of the VCV.
12. The HIPS of claim 8, wherein the safety logic solver is programmed to designate the closed SSVs for use as an operating set of SSVs, if, during the test period, the pressure between the closed SSVs does not rise above a predetermined threshold value.
13. The HIPS of claim 1, wherein the VCVs are closed during normal operations and during a full-stroke test.
14. The HMS of claim 1 further comprising manual shut-off valves positioned upstream and downstream of each of the parallel sets of SSVs for isolating each of the SSV sets from the adjacent piping system.
15. The HIPS of claim 1 which is integrally mounted for transportation on a movable platform.
16. The HIPS of claim 1, wherein the SSVs are provided with electrically powered failsafe valve actuators, whereby the valves are moved to a closed position in the event of a power failure.
17. The HIPS of claim 1 in which the VCVs are electrically operated.
18. A method for the operational safety testing of a high integrity protection system (HIPS) connected to a wellhead pipeline system, the method comprising:

providing an HIPS that has first and second sets of surface safety valves (SSVs) in fluid communication with the piping system, the two sets being in parallel with each other, each set of SSVs having two SSVs in series, the SSVs being operable in response to signals from a safety logic solver;

moving the first set of SSVs from an open position to a closed position for a tight shut-off safety test while the second set of SSVs is open as a flowline for the pipeline system; and actuating an alarm signal if the first set of SSVs do not maintain the pressure in the piping between the SSVs at or below a predetermined threshold level.
19. The method of claim 18 in which at least one pressure sensing transmitter positioned between the closed SSVs transmits a signal to the safety logic solver that corresponds to the pressure of fluid in the piping between the two closed valves.
20. The method of claim 18 which includes venting the pressurized fluid between the closed SSVs at the beginning of the safety test.
21. The method of claim 18 which includes recording the pressure of the fluid in the section of piping between each set of SSVs before and during the safety shutoff testing of the valves.
22. The method of claim 21 which includes providing a display of the recorded pressure levels.
23. The method of claim 18, wherein the second set of SSVs remains open while the first set of SSVs is returned to the fully open position.
24. The method of claim 23, wherein an alarm is actuated if the first set of SSVs do not open fully.
25. The method of claim 18 which includes:

providing each of the two sets of surface safety valves (SSVs) with a vent control valve (VCV); and opening the VCV connected to the first set of SSVs for a predetermined period of time to effect the pressure venting when the first set of SSVs are closed.
26. The method of claim 23 further comprising:
moving the first set of SSVs to the open position;
moving the second set of SSVs to the closed position;

measuring the pressure between the SSVs of the second set of SSVs for a predetermined period of time; and actuating an alarm signal if the second set of S S V s do not maintain the pressure in the intermediate piping at or below a predetermined level.
