Engineering and design for LNG project in Qatar

Emerson has completed the digital automation engineering and design for the US$12 billion Qatargas II facilities expansion, one of the world's largest Liquefied Natural Gas projects

Emerson has completed the digital automation engineering and design for the US$12 billion Qatargas II facilities expansion, one of the world's largest Liquefied Natural Gas projects Emerson, the main instrumentation and controls contractor (MICC) for the project, has begun integration and testing of the digital automation system, and will install its PlantWeb digital architecture, assist with the expansion project commissioning and start-up, and provide operator training.

The Qatargas II expansion, a joint venture of Qatar Petroleum, ExxonMobil and Total, will add onto the existing Qatargas site at the Ras Laffan Industrial City, which has three operational LNG units - or trains - producing 8 million tons of liquefied gas annually.

Phase one of the QG-II expansion includes LNG train number 4, scheduled to begin delivery of 7.8 million tons LNG per annum to the United Kingdom in mid 2008.

Train number 5 is then scheduled to produce an additional 7.8 million tons per annum nine months later.

These LNG liquefaction trains are two of the largest in the world.

Emerson PlantWeb digital plant automation architecture will be installed as part of the expansion to help Qatargas achieve their goal of producing 45 million tons of Liquefied Natural Gas annually by 2010.

PlantWeb integrates plant-wide operations for optimum process control, operational excellence, and management information.

PlantWeb uses a Foundation fieldbus-based network of intelligent field devices to deliver continuous process and equipment health information: these include Emerson Rosemount transmitters, Micro Motion Coriolis flowmeters, Fisher valves with Fieldvue digital valve controllers, and the AMS Suite predictive maintenance software.

AMS Suite applications deliver diagnostics and guidance that help unit operators and maintenance personnel optimise performance and availability.

Post start-up services by Emerson will include a multi-year commitment to furnish and manage hardware and software for plant automation systems; safety instrumented systems, training simulation, plant-wide data historian, transmitters, valve positioners, and advanced control solutions.

"Emerson is excited to be a key part in helping Qatar Petroleum achieve its vision of being the world's largest supplier of liquefied natural gas and condensates," said John Berra, president of Emerson Process Management.

"Emerson are very committed to Qatargas and the LNG industry.".
