N Sea offshore wireless success on heat exchanger
Emerson Process Management has successfully applied its wireless self-organising mesh field network to monitor wellhead annular pressure and heat exchanger pressures on the Grane offshore platform
The team verified the reliability and coexistence performance of the network, and also deployed it in the plant.
"When Emerson first approached me with their industrial wireless solution, they said it was plug and play" said Tim Gerami, senior design engineer at PPG: "I have to admit I laughed; nothing I'd seen so far was that easy.
But I'm a believer now.
Five minutes after installing the Smart Wireless system, the wireless network came to life.
It's been there ever since".
This Smart Wireless network uses ten wireless Rosemount transmitters for pipeline and steam header temperature measurement, which enables operators to watch for cold spots and adjust steam throughput.
PPG also plans to use the Smart Wireless solutions to do temperature profiling of the entire expansive plant, enabling load sharing and balancing to maintain superheated steam plant-wide.
PPG has also commissioned eight wireless Rosemount transmitters on the self-organizing mesh for tank level measurements, to provide back-up of the primary radar level measurements, helping to ensure level control.
Wireless transmitters allow PPG to install new instrumentation, that would normally be cost-prohibitive in the plant, that covers approximately 765 acres and is dense with pipes, buildings and equipment.
PPG estimates installation costs for wired instruments of nearly USD20 per foot for wiring and conduit.
These wireless measurements have the potential to increase process reliability and provide a low-cost redundant back-up measurement.
PPG is using wireless to make operational improvements by capturing and using new data, and is also anticipating cost advantages.
When queried about maintenance on the Emerson Smart Wireless network, Reese Borel, process control specialist at PPG responded: "I haven't had to do any.
It just runs". Request a free brochure from Emerson Process Management - Wireless ...
