The system supplies crude oil to refineries in Feyzin, Cressier, Reichstett, and Karlsruhe.

[1] The main 769-kilometre-long (478 mi) 34-inch (860 mm) pipeline starts in Fos-sur-Mer (Lavera) in France and runs through Strasbourg to Karlsruhe in Germany.

Another 714-kilometre-long (444 mi) 40-inch (1,000 mm) pipeline runs from Fos to Strasbourg (Oberhoffen-sur-Moder), and 260-kilometre-long (160 mi) 24-inch (610 mm) pipeline runs from Fos to Lyon (Feyzin).

The maximum discharge of the system is 35 million metric tons per year, although the real used annual amount is approximately 23 million metric tons per year.

[6][7] In August 2009, a breach in the pipeline led to crude oil spilling into Réserve naturelle nationale des Coussouls de Crau, a nature reserve in France.
