Managing a 1600 kilometer long oil pipeline is no simple task, even for the leading oil pipeline company in Russia that owns the largest oil pipeline system in the world.

The company has built a fiber optic backbone based on SDH multiplexers to transmit standard E1 data streams over long distances. The backbone is connected with a variety of systems, such as the ventilation system, air conditioning system, and fire alarm system. In order to transmit such a large amount of data aggregated from numerous systems, the backbone must provide sustainable bandwidth for real-time delivery. Long-distance fiber optic ability is also a must for this cross-country pipeline.

Gigabit redundant ring for high data availability

Rugged design capable of operating under harsh environmental

To make sure that all data is transmitted accurately and immediately, a Gigabit Ethernet network consisting of more than 1,000 Moxa EDS-510A industrial Ethernet switches was constructed. The EDS-510A provides up to three Gigabit Ethernet ports, making it ideal for building a Gigabit backbone with high bandwidth capability. In addition, the EDS-510A switches support fiber optic transmissions of up to 80 km, providing high cost-effectiveness by significantly reducing the number of installations required. With a -40 to 75˚C operating temperature range, the EDS-510A switches are able to operate reliably in harsh Russian industrial environments. At each node along the pipeline, a Moxa ioLogik E2210 Active Ethernet micro controller is installed to allow for communications between the sensors and the Ethernet network, so that actions can be taken automatically during unexpected events. The Ethernet network was configured in a Turbo Ring topology to ensure data availability at all times with a fast recovery time of less than 20 ms. Overall, Moxa’s ruggedized switches and I/O products were a perfect fit for the harsh environment.
