Transalpine Pipeline - From the Adriatic to the Centre of Europe through the Alps

The Transalpine Pipeline (TAL) is 753 km long and passes through Italy, Austria and Germany, connecting the Port of Trieste with the German States of Bavaria and Baden-Württemberg.

The TAL system is divided into three sections:

  • Image
    TAL-IG (diameter 40”): connects the tank farm in San Dorligo della Valle (Trieste) with the tank farm in Lenting (Ingolstadt) and has a total length of 465 km and six intermediate pumping stations (three in Italy: Reana, Cavazzo and Paluzza, two in Austria: Kienburg and Gruben and one in Germany: Steinhöring).

    The pipeline runs for 145 km inside Italy (Friuli Venezia Giulia). Starting from the coastal depot at San Dorligo della Valle, it traces a wide arc around Trieste and continues along the Karst plateau, parallel to the Slovenian border, before reaching the Province of Gorizia.

    It passes east of Monfalcone and is carried on columns across the River Isonzo before continuing northwards past Manzano, Remanzacco and Tricesimo in the Province of Udine. Near Osoppo it crosses the River Tagliamento alongside the motorway, heads towards Lake Cavazzo and then recrosses the River Tagliamento before passing Tolmezzo and descending into the valley of the River But.

      After crossing the river a dozen times the pipeline passes west of Paluzza and Timau and through the 7 km long Monte Croce Carnico Tunnel across the border into Austria. Within Austria, it crosses the Alps via the Gail Valley and the Gailbergsattel and then continues along the Drau Valley near Lienz and the Isel Valley and through the Tauern Tunnel before arriving at the Felbertauern Tunnel, where it reaches its maximum altitude of 1,572 metres above sea level.

    After crossing the Salzach Valley in Mittersill, the pipeline then continues across the Thurn Pass to the south-west of Kitzbühel and through the Hahnenkamm Tunnel before reaching Going and descending to the German border at Kufstein/Kiefersfelden.

    Once in Bavaria the pipeline descends the Inn Valley and then continues to the west of Rosenheim and Wasserburg before heading north to the refineries in Vohburg and Ingolstadt.

    Along its entire route, the route of the pipeline is indicated by a series of markers with special signs showing the progressive mileage and the telephone number of the responsible control room.

    TAL-IG supplies the following refineries:

    - OMV refinery in Schwechat near Vienna (through the Adria-Wien Pipeline system which is connected in Würmlach
    - OMV refinery in Burghausen (via the OMV deposit in Steinhöring)
    - Czech refineries in Kralupy and Litvinov (via the MERO system in Vohburg)
    - Bayernoil refinery in Vohburg
    - Gunvor refinery in Ingolstadt
  • TAL-NE (diameter: 26") a total lengh of 22 km connects the Gunvor refinery in Ingostadt and the tankfarm in Lenting with the Bayernoil refinery in Neustadt.

 

  • TAL-OR (diameter 26") a total length of 266 km and the three pumping stations (Ingolstadt, Ehringen and Hohenhaslach) connects the tankfarm in Lenting with the MiRO refinery in Karlsruhe.

THE TAL INSTALLATIONEN

From the operational point of view, the TAL system is run by two separate control rooms:

Image
The control room in Italy manages:

  • the tank farm in San Dorligo della Valle;
  • the TAL-IG South route (composed of the Italian route and the southern part of the Austrian route up to the Felbertauern Tunnel).

The control room in Germany manages:

  • the TAL-IG North route (composed of the northern part of the Austrian route and the German section of TAL-IG);
  • the Lenting tank farm;
  • the TAL-NE route;
  • the TAL-OR route.

The pipeline is operated in such a way that each refinery receives the quality and quantity of oil required at the scheduled time.This is made possible by careful operational planning that ensures the safe operation and maximum reliability and efficiency of the supply system.
