Today’s oil and gas operators are moving decisively to capitalize on the innovations driven by the Industrial Internet of Things (IIOT). Benefiting from these networking opportunities means real-time remote monitoring of wellheads. This gives operators the power to continually ensure consistent pressure and flow, as well as transmit data throughout the network for ongoing process improvement. Wellhead control automation often includes compressor control, pumping unit control, gas lift control, injection control and more.
A vital function that is often unaccounted for in initial network architectures is built-in redundancy, the capability of the network to quickly reroute traffic in case of a failure at a particular point—fail-safes that help ensure uninterrupted uptime and optimal productivity. Unfortunately, many operations learn the hard way because they don’t account for redundancy. Operations often run in tough environments that can damage equipment and cabling. Without a contingency option, data flow is often completely stopped until maintenance teams can be deployed.
Fortunately, with today’s technologies, there are many options for building redundancy into networks, or readily retrofit existing networks as the case may be. This redundancy ensures that if one route goes down, another immediately takes its place. Belden and its portfolio of brands, for example, provide a complete series of products that can help protect every level of devices—from the network infrastructure backbone to the remote sensors at each wellhead. Systems are ruggedized and designed to modularly integrate together and include components such as Belden industrial Ethernet cabling, Hirschmann backbone and field switches, Hirschmann/Tofino Security Appliances and Tripwire Cyber Security Software.
There are many kinds of ring and subring topologies to select from as well as both wired and wireless solutions to protect everything from network infrastructure to vulnerable field devices, in the Media Redundancy Protocol (MRP) and Parallel Redundancy Protocol (PRP). In fact, Belden’s Hirschman group is well known for developing both of these common protocols and later made them open standards, ensuring even more choices for operators.
Many of these choices are illustrated in the schematic below. The detailed Industrial Ethernet network depicted is highly robust and secure, with multiple layers of redundancy on both the cable and hardware levels. In addition, there are strategically placed security appliances ensuring that data flows only where it is desired and that only proper personnel have access to it.
Overall, the schematic suggests many possibilities to “mix and match.” We are happy to talk through this to help you decide what concepts might be best for your operation. The key takeaway for now is that there are many choices for redundancy, and an option is out there that best meets your specific needs.
Network redundancy solutions apply to other oil and gas challenges—and other industries too
The retrofitting of network redundancy is a huge issue for wellhead monitoring operations today, but it is by no means the only area in the oil and gas industry where redundancy can be beneficial. Two we hear about often are pump station monitoring, where pipeline pressure and flow data is transmitted to and from central monitoring areas, and real-time monitoring at refineries for issues such as gas leaks. The illustrated redundancy technologies can be readily applied in these applications as well, helping achieve greater safety and reliability and avoiding costly network interruptions.
The examples in the schematic can also readily apply to applications in other industries. For example, mining, power utilities, manufacturing and wastewater are all industries where retrofitting redundancy is boosting uptime and productivity in network applications of many kinds.
