Abstract

A well production system comprises a barrier providing a pressure barrier between components of the well production system located upstream of the barrier and components of the well production system located downstream of the barrier; a safety instrumented system (SIS) communicatively coupled to the barrier and having one or more logic solvers; one or more pressure transmitters disposed along a flowpath, within the barrier, and communicatively coupled to the one or more logic solvers; one or more valves disposed along the flowpath within the barrier and communicatively coupled to the SIS, wherein the SIS is configured to selectively actuate the one or more valves based on feedback from the one or more pressure transmitters; a spare pressure transmitter disposed along the flowpath within the barrier; and a monitoring device, wherein the monitoring device is configured to selectively couple the spare pressure transmitter to the one or more logic solver.
