Instrument Signal Concentrators

Remote Emergency Shutdown Device Improves Safety and Performance at Oil Production Platform - Jim McConahay and Richard Conway - When Italian multinational oil and gas company ENI Petroleum needed help designing a real-time communications link to its Devil's Tower oil well platform off the coast of Louisiana, they turned to Moore Industries for help. By integrating our NCS NET Concentrator System® into their communications system, ENI Petroleum has developed a reliable method for dealing with potential emergency situations that meets new federal regulations and reduces the possibility of false shutdowns - from Moore Industries and Control Design.
