CENAGAS, TETRA and SCADA for 9,500 Kilometres of Gas Pipeline
The Centro Nacional de Control del Gas Natural (CENAGAS) is a decentralized agency of the Mexican Federal Public Administration, dedicated to the management, administration and operation of the Integrated National Natural Gas Transportation and Storage System.
CENAGAS required a redundant, high availability telecommunications system that would guarantee the continuity of the remote operation of natural gas transportation without interruption, through the transfer of real-time, historical information and operational variables to the CENAGAS SCADA, with 24/7 industrial monitoring through a NOC/ SOC. The gas operator has 347 remote station sites located along a 9,400 km pipeline.
CENAGAS’ SCADA system receives an average of 70,000 signals from the different types of existing surface stations. CENAGAS has a high availability satellite link system to provide voice and data coverage to 347 sites with remote stations located throughout the country.
The main objective of the project was to provide CENAGAS with an alternative (redundant) communication system to the current one, which would provide transmission signal coverage to the 347 existing remote stations, thus increasing the availability levels of the services, which contribute to guarantee the safety, operational efficiency, reliability and integrity of the natural gas transportation through the pipeline.
In addition, an availability target of at least 99.975% was set for data transfer and monitoring at each of the remote stations of the natural gas transportation system.
