|From||Hassi R'Mel, Algeria|
|Passes through||Mediterranean Sea, Sardinia|
|Partners||Sonatrach, Edison S.p.A., Enel, Sfirs, Hera Trading|
|Length||1,505 km (935 mi)|
|Maximum discharge||10 billion cubic meters per year|

In 2007, while surveying the proposed route between Sardinia and Algeria, sonar data from an Underwater Autonomous Vehicle revealed a large wreck, later determined to be the French battleship Danton, sunk in 1917.
The pipeline will start from the Hassi R'mel field in Algeria and the 640 kilometres (400 mi) section will run to Koudiet Draouche at the coast of Mediterranean Sea. The 285 kilometres (177 mi) offshore section with two legs will be laid between Koudiet Draouche and Porto Botte (CI), Sardinia. The Sardinian section is planned approximately 300 kilometres (190 mi) from the south to Olbia. The offshore section between Sardinia and Italian mainland is 280 kilometres (170 mi) and the landfall will be Piombino (LI). It will be connected to the existing Italian gas grid in Tuscany.
The pipeline diameter will vary between 22 inches (560 mm) and 48 inches (1,220 mm). The initial capacity will be 8 billion cubic meters (bcm) of natural gas per annum. Total estimated costs of project are €2 billion. The pipeline is expected to become operational in 2014. The Italian section will be built by Snam Rete Gas.
