Abstract: A technique facilitates collection of information on desired production related parameters in a subsea valve system. Collected data can be processed in a manner that enables enhanced production and/or an increased knowledge regarding operation of the entire subsea valve system. Sensors are coupled with a plurality of subsea valves, and those subsea valves are positioned at appropriate locations along a subsea hydrocarbon production system. The sensors also may be coupled with a data processing system to process the collected data for use by a well operator.
