In 2007, while surveying the proposed route between Sardinia and Algeria, sonar data from an Autonomous Underwater Vehicle (AUV) revealed a large wreck, later determined to be the French battleship Danton, sunk in 1917.
The pipeline would start from the Hassi R'mel field in Algeria and the 640 kilometres (400 mi) section would run to Koudiet Draouche on the coast of Mediterranean Sea. The 285 kilometres (177 mi) offshore section with two legs would be laid between Koudiet Draouche and Porto Botte (CI), Sardinia. The Sardinian section would be 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 would be Piombino (LI). It would be connected to the existing Italian gas grid in Tuscany.
As of 2021 project is considered to be shelved.
The pipeline diameter would vary between 22 and 48 inches (560 and 1,220 mm). The initial capacity would be 8 billion cubic meters (bcm) of natural gas per annum. Total estimated costs of project are €2 billion. The pipeline was expected to become operational in 2014. The Italian section should have been built by Snam Rete Gas.
