Safety integrity level (SIL) 3 high-integrity protection system (HIPS) fully-functional test configuration for hydrocarbon (gas) production systems

摘要

A selection of a hydrocarbon well of a hydrocarbon production system is received at a safety logic solver (SLS) for proof testing. Test mode pressure sensors attached to a common header of the hydrocarbon production system are activated to monitor a live process condition status of the common header from all wells of the hydrocarbon production system. A simulated overpressure condition is induced in the operation pressure sensors. An indication of overpressure is received at the SLS from at least two operation pressure sensors. Final elements associated with the hydrocarbon well are signaled to close while leaving other wells in the hydrocarbon production system in operation. The operation pressure sensors are restored to a normal pressure condition, and the final elements associated with the selected hydrocarbon well are signaled to re-open the hydrocarbon well.
