Italian Contractor Bonatti Enters Argentina Through Landmark LNG Pipeline Project
The infrastructure, designed to connect the Vaca Muerta shale formation with the Atlantic coast, will become the country's largest-diameter gas trunkline and a cornerstone of Argentina's strategy to become a global LNG exporter.
Italy's energy infrastructure expertise is set to play a central role in one of Latin America's most ambitious natural gas projects.
Engineering and construction company Bonatti, headquartered in Parma, will make its first investment in Argentina after being selected to participate in the construction of the main pipeline for the Argentina LNG export initiative, a project expected to reshape the country's position in global energy markets.
Bonatti forms part of an international consortium alongside U.S.-based Pumpco and Argentina's Contreras Hermanos, which was awarded the civil works contract for the 527-kilometer, 48-inch gas pipeline linking the Vaca Muerta shale basin with the port of Sierra Grande, in Río Negro province. Once completed, it will be the largest-diameter natural gas pipeline ever built in Argentina.
The infrastructure is a critical component of the Argentina LNG project, led by YPF, Italy's ENI and XRG, the international investment arm of Abu Dhabi's ADNOC. The pipeline is expected to transport up to 100 million cubic meters of natural gas per day, supplying future liquefied natural gas export facilities on Argentina's Atlantic coast.
Europe strengthens its role in Argentina's energy transition
Bonatti's arrival underscores the growing role of European companies in Argentina's energy expansion.
With nearly eight decades of experience developing large-scale pipeline infrastructure across Europe, Africa and the Middle East, Bonatti has participated in strategic projects such as Germany's Zeelink gas pipeline and multiple Mediterranean energy corridors. The company recently secured €100 million in financing to support its international growth strategy through 2029.
Its participation also reinforces Italy's position within Argentina's rapidly expanding energy sector, where ENI has emerged as one of YPF's principal international partners in developing LNG export capacity.
Vaca Muerta aims for global LNG markets
The pipeline represents one of the largest infrastructure investments associated with the development of Vaca Muerta, the world's second-largest shale gas reserve.
The first phase of Argentina LNG is expected to export 12 million tonnes of LNG annually through two floating liquefaction units, positioning Argentina as a new supplier for energy-hungry markets in Europe and Asia. A final investment decision is expected during the second half of 2026.
The project is part of a broader strategy to transform Argentina from a regional gas producer into a major global LNG exporter, leveraging the country's abundant unconventional gas resources.
A strategic opportunity for Europe–Latin America energy cooperation
For Europe, Bonatti's involvement highlights the deepening industrial ties between European engineering firms and Latin America's energy sector.
As European countries seek to diversify energy sources and strengthen long-term supply security, investments in Argentina's natural gas infrastructure have gained strategic importance.
For Argentina, the participation of internationally recognized contractors brings technical expertise, project execution capabilities and greater confidence among global investors financing multi-billion-euro energy developments.
The construction of the new trunkline therefore represents more than a major engineering contract.
It reflects the growing convergence between European industrial capabilities and Latin America's energy ambitions, reinforcing Argentina's emergence as a future LNG exporter while creating new opportunities for European companies in one of the world's fastest-growing natural gas markets.
