This will require expansion of the West Austria gas pipeline (WAG), which runs between the Slovakian border – starting in Baumgarten, near Vienna – and the German border near Oberkappel. Within the framework of the WAG +600 project, existing compressor stations will be expanded, new ones will be erected and new pipeline sections will be built parallel to the existing pipeline. Siemens will supply the electrical equipment and field instrumentation for the Rainbach, Kirchberg and Baumgarten compressor stations, for the Kirchberg-Lichtenau and March-Baumgarten loops, and for the valve and pig stations along the pipeline. The equipment consists of low-voltage switchgear installations, converters, transformers, uninterruptible power supply (UPS) systems, emergency-power diesel and battery equipment, as well as fire and gas alarm and cathodic protection equipment.
