Yokogawa Selected to Supply Cheniere's LNG With Integrated Automation and Safety System
SPL is the first company that has received approval from the Department of Energy to export liquefied natural gas (LNG) to non-Free Trade Agreement countries. The development of liquefaction services at the Sabine Pass LNG receiving terminal in Cameron Parish, La., will transform the terminal into a bi-directional facility capable of liquefying and exporting natural gas and importing and re-gasifying foreign-sourced LNG.
Yokogawa's Centum VP integrated production control system was selected for the new liquefaction facility. While Centum VP is classified as a distributed control system (DCS), it goes beyond a traditional DCS by offering a more intuitive human machine interface and a large-capacity field control station to process data faster while maintaining exceedingly high reliability. The dual-redundant configuration of processor cards combined with pairing each processor card with two CPUs (pair & spare configuration) ensures uninterrupted operations and high availability.
SPL will also use the ProSafe-RS integrated safety instrumented system (SIS) from Yokogawa for the site. ProSafe-RS delivers completely integrated SIS for DCS to simplify deployment, operation, and maintenance. Until now, two separate monitoring and operating environments were required for the DCS and SIS. ProSafe-RS eliminates the need to implement separate communications and distinctive hardware architectures for the DCS and SIS, therefore fast tracking implementation at Sabine Pass, lowering overall costs, and simplifying operation and maintenance.
