Constant flow thanks to redundant Ethernet rings

The aim of the project is to significantly increase the pipeline flow rate while at the same time improving the reliability of the system. The major environmental issues and the necessity for control of the entire installation (pipeline and automation equipment) require a modern and reliable communication technology over long distances.

After all, the operators must be able to identify the exact location of potential leaks quickly and assess unexpected reduction in performance.
The devices must be easy to use so operating personnel can use it after just a short training period.

Project parameters

Ethernet technology has entered into the automation field and enables communication surroundings, which are cost-effective in their implementation. As in many industrial applications, a secure transfer of data over long distances is also essential for the pipeline installations in Kazakhstan.

Requirements

• The pipeline network covers around 6000 km
• The system covers several pump stations
• The oil pressure is kept at approx. 50 bar (thanks to scaleable control and surveillance technology from ABB)
• The stations must also give information regarding potential leaks

Solution

• The mid-sized networks in the pump stations are equipped with cost-effective RS2-FX/FX Ethernet switches from Hirschmann™ in a redundant configuration (mounted on DIN rails). A LED on the front of the switch shows the faults. The first remote diagnostics is possible of a web server, which is served by the device
• The Hirschmann™-HiOPC-Software serves as a gateway and makes the SNMP data available in OPC format
• Switches from the series MS-3124-4 have also been installed
• The switches are connected with the help of a LWL-ring topology

Why Hirschmann™?

Hirschmann™ offers a reliable and high-performance network based on redundant Ethernet technology, fulfilling all kinds of demands. The special environmental conditions require devices, suitable for operation in harsh environmental temperatures. The patented HIPER ring technology from Hirschmann™ enables extremely reliable and stable networks while lowering the installation requirements and costs.
