The Algeria-Sardinia-Italy (GALSI) gas pipeline is a strategic infrastructure project that spans several countries, connecting Algeria, Sardinia, and mainland Italy. The project aims to transport natural gas from Algeria’s Koudiet Draouche region, crossing the Mediterranean Sea to Sardinia, and further on to Tuscany in Italy. The pipeline plays a critical role in enhancing the energy supply to Europe, providing a reliable source of natural gas.

The pipeline system includes:

  • A 100 MW compressor station in Algeria.
  • A 26-inch deepwater offshore pipeline to the south coast of Sardinia.
  • An onshore 48-inch pipeline traversing Sardinia.
  • Compressor and metering stations in Sardinia and Tuscany.
  • A 36-inch offshore pipeline from Sardinia to mainland Italy.
  • The connection to the existing gas network in Tuscany.

This extensive infrastructure is designed to transport natural gas efficiently across various terrains, from offshore deepwater pipelines to onshore systems, ensuring a secure and consistent energy supply for Europe.

Sofregaz was responsible for delivering Pre-FEED and FEED services for key components of the GALSI pipeline project. 

Our scope of work included:

  • Transmission system configuration studies: Evaluating the most efficient gas transportation solutions for the cross-country pipeline.
  • Pre-FEED of compressor stations: Design and technical specifications for compressor stations in both Algeria and Sardinia.
  • Pre-FEED of pressure reduction and metering stations: Focused on metering stations in Sardinia and Tuscany, critical to ensuring precise gas flow measurement and management.
  • SCADA and telecommunications systems: Developing communication and control systems to ensure the operational safety and efficiency of the pipeline.

Throughout these phases, Sofregaz played a key role in cost estimation, providing implementation schedules, and ensuring the technical specifications aligned with the highest industry standards.

  • Cross-Country Reach: The GALSI pipeline spans from Algeria to Italy, delivering gas across both deepwater and land-based routes.
  • Energy Infrastructure: The pipeline is a vital link in securing energy supplies for Italy and the broader European market.
  • Technical Expertise: Sofregaz’s involvement in the Pre-FEED and FEED phases ensured the efficient design of the pipeline, compressor stations, and associated facilities.

This project strengthens Europe’s energy infrastructure, leveraging Sofregaz’s expertise in gas transmission systems and large-scale pipeline design.
