Automation Technology Moves Towards The Wireless Era
Working Case Studies: Wireless Automation for North Sea Oil
Monitoring in inaccessible area: StatoilHydro is the leading oil and gas operator on the Norwegian continental shelf. The Grane platform is operated by StatoilHydro, and is stationed in the Norwegian Sea off the coast of Bergen, Norway.
Problem: To remotely monitor wellhead and heat exchanger in harsh, difficult to reach areas crowded with metal pipe work, walkways and other obstructions.
Solution: Emerson Process Management has successfully applied its wireless selforganising mesh field network to monitor wellhead annular pressure and heat exchanger pressures on the Grane offshore platform.
How Non–Intrusive WSNs Helps To Quickly React to any Loss of Well Pressure
Problem: To early detect the flow loss to enable operators to flow the well through the test separator and thus re-establish flow by reducing pressure. Bringing flow back quickly improves throughput and significantly increases production.
A non-intrusive flow metering solution required that could be implemented without shutdown and production loss in heavily crowded area (to be mandatorily kept clear for safety reasons) without cabling, cable trays and junction boxes.
Solution: Emerson‘s wireless temperature transmitters were installed to indirectly indicate flow on lines at each of forty wells. In contrast with the once-a-shift manual recordings, the wireless devices now transmit readings every 30 seconds back to the wireless gateway. Gateway is hardwired directly into the existing control system providing operators with the real time information; they need to react quickly to any change in flow.
