HIGH INTEGRITY PROTECTION SYSTEM FOR HYDROCARBON FLOW LINES

A high integrity protection system includes a flow line that includes an inlet and an outlet. The inlet can be connected to a first source of pressure. The system includes a first surface safety valve (SSV), a second SSV, and pressure sensors installed on the flow line between the inlet and the outl...

Beschreibung
Zusammenfassung:	A high integrity protection system includes a flow line that includes an inlet and an outlet. The inlet can be connected to a first source of pressure. The system includes a first surface safety valve (SSV), a second SSV, and pressure sensors installed on the flow line between the inlet and the outlet. The system includes a logic solving processor in communication with the pressure sensors, the first SSV, and the second SSV. The logic solving processor can perform operations including transmitting signals to control the first SSV and the second SSV. The system includes a second source of pressure that can be connected to the flow line between the inlet and the first SSV. When the first source of pressure ceases to provide fluid pressure to the system, the second source of pressure can provide fluidic pressure to the flow line to test a fluidic integrity of the system.
