Apolo,
Flowserve has upgraded several refineries from the APEX system to a National Instruments cRIO Data Acquisition system.
Repsol in Cartagena, Spain
Tupras in Izmit, Turkey
BP in Whiting, Indiana (in progress)
All sites took a few weeks to implement, but were done outside of a major outage. No coke cutting operation was impacted while implementing this change. But all sites were able to utilize a small (several day) outage window to do the actual hardware replacement. Most of the commissioning time was implementing and testing some of the new automation functionality we were able to implement with the cRIO.
