GALSI ({{langx|it| Gasdotto Algeria Sardegna Italia}}) was a planned natural gas pipeline from Algeria to Sardinia and further northern Italy, as an extension to the TransMed Pipeline.

History

The feasibility study was completed in 2005. The intergovernmental agreement on the GALSI pipeline was signed between Italy and Algeria on 14 November 2007.

Early in 2008 one of the project founders, Wintershall, sold its share to other shareholders and left the project.

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.

Route

The pipeline would start from the Hassi R'mel field in Algeria and the {{convert|640|km|mi}} section would run to Koudiet Draouche on the coast of Mediterranean Sea. The {{convert|285|km|mi}} offshore section with two legs would be laid between Koudiet Draouche and Porto Botte (CI), Sardinia. The Sardinian section would be planned approximately {{convert|300|km|mi|-1}} from the south to Olbia. The offshore section between Sardinia and Italian mainland is {{convert|280|km|mi}} and the landfall would be Piombino (LI). It would be connected to the existing Italian gas grid in Tuscany.

The exact offshore route should have been selected by Dutch engineering contractor Fugro by July 2008.

As of 2021 project is considered to be shelved.[https://www.snam.it/export/sites/snam-rp/repository/ENG_file/Governance/Social_bodies/Shareholders_meeting/Minutes_documents/2021/Domande-Snam-AGM-2021_azionista-ReCommon_ENG.pdf Ordinary Shareholders' Meeting of Snam S.p.A. 28 April 2021]

Technical features

The pipeline diameter would vary between {{convert|22|and|48|in|mm|-1}}. 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.
