downtime by incorporating its Smart Wireless technology into the Rosemount 3051 pressure transmitter.
Te 3051 delivers a full suite of solutions for
pressure, level and flow, providing the process industry with a new option for monitoring additional assets, reducing energy costs and increasing process efficiency while providing a safer environment for its employees. Delivering maintenance-free performance with five-year stability and a ten-year power module life, Emerson says it is an effective and reliable way to wirelessly monitor assets and reduce downtime. Equipment failure is the cause of nearly half of an operation’s downtime, yet many assets go unmonitored due to cost constraints. Emerson says the 3051 can monitor many assets throughout an operation with a 40-60 per cent cost savings over wired installations. Significant costs can arise when unmonitored
variations occur, causing quality to degrade and throughput to decrease. Increasing the number of measurements will provide better insight into the process and help reduce variation, but the time and cost to add new measurement can be a barrier. With Rosemount 3051 wireless devices, operations can install additional measurement points quickly and economically, providing the precise and stable measurements needed to reduce variability and maximise throughput. Users can monitor flow and pressure in
compressed air, steam and water systems to benchmark energy usage, identify energy savings opportunities throughout an operation, and provide energy management and accurate internal billing. Meanwhile Emerson’s wireless technology is helping RWE maximise gas storage capacity
and improve efficiency and safety at its Dolní Dunajovice underground gas storage facility in the Czech Republic. Installation of five Smart Wireless networks
and more than 100 wireless measurement devices has increased visibility into the process, enabling the plant to improve control and run closer to its capacity. Automating data collection has also eliminated manual rounds at the plant, improving operator efficiency and safety. “We needed to upgrade our existing
instrumentation and add additional measurements, but with just two short windows of opportunity each year and no available existing cabling infrastructure, it was impossible to complete the work within the scheduled two-week downtime,” said Pavel Šilinger, energy manager, RWE Gas Storage. “Extending the downtime would cost RWE an estimated US$250,000 (€188,000) a day in lost income.” RWE needed a solution that did not require installation of new cabling and allowed a longer period for the upgrade to be completed. To meet this need, it selected Smart Wireless technology from Emerson. Based on IEC 62591 (WirelessHART) communications, the technology is well-proven, reliable and both quick and easy to install and commission. Te wireless solution did not require RWE to
install new cabling or new I/O cards in the control host. RWE simply added Smart Wireless gateways to the existing Modbus network and all data from the new wireless transmitters was then available within the existing control system. Tis meant that the plant could continue to operate while new instruments were being installed, removing the need for the upgrade to be completed within the scheduled two-week downtime.
Wireless network overcomes jungle challenge A
n industrial wireless system supplied by Redline Communications has been chosen by a major oil producer in South America to be the basis of its new wireless infrastructure. Te company’s system, already in use in dozens of oil fields in the USA and the Middle East, will connect hundreds of access nodes, which in turn will link thousands of machine- to-machine devices across a 596km2 oil field in the tropical jungles of South America. Te system will be capable of delivering the increasingly

high performance requirements that these complex networks require, and is able to accommodate virtually any networked device or application, not just today but in the years to come. “We are thrilled to be providing a
wireless solution for our first major oil field in South America, and we expect that it will be one of many for this customer as they have several fields in the region,” said Carl MacKinnon, vice president worldwide sales. “Tis win is part of our stated growth plan: develop relationships with new customers to prove the value of
our networks, expand with them in the same field as more services and connectivity is needed, then expand to other fields and eventually offer more products and services to them as we learn more about their unique needs.” Te Virtual Fibre network will be built using Redline’s nomadic RAS platform, RDL-3000 and eLTE-MT systems. All are rugged, reliable and secure wireless broadband equipment designed by the company for harsh environments and engineered and built to the exacting standards required by the energy sector. ●
