Pump Stations for Pipeline networked with PROFIBUS

ABB drafted a financing model of the 43 million $US project for the general contractor and was the main contractor for the entire control technology. The oil in the pipeline is at 50 bar pressure in order to ensure high and uniform flow. Pump stations are needed at regular intervals for this. At the field level, reliability is also important. Therefore, the controls are connected to the sensors and servo motors with optical profibus rings. The higher-level data network in the pump stations is realized with redundant Ethernet rings. The entire station data is routed from the individual pump stations, via the extensive telecommunication networks, to a central control room. In the individual pump stations, control and monitoring technology from ABB is used.

All components important for operation are designed in duplicate, and work with distributed intelligence in multiple controller pairs networked via profibus and Ethernet. Constant monitoring of pressure and flow makes it possible to detect and localize leaks in the pipeline train. The operating and monitoring system warns the system personnel when there is a malfunction, so that the appropriate measures can be introduced. A powerful, and reliably-working profibus and Ethernet network, even under adverse storm conditions, is the basis for the entire control and monitoring functions and enables future expansion through modern technology.
