Abstract
A well production system comprises a safety instrumented system (SIS) having one or more logic solvers; one or more pressure transmitters disposed along a flowpath and communicatively coupled to the one or more logic solvers; one or more valves disposed along the flowpath 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; and a spare pressure transmitter disposed along the flowpath, wherein the spare pressure transmitter is configured to be selectively coupled to the one or more logic solvers.
