- Gaztransport & Technigaz SA (GTT) is a French engineering company specializing in the design and development of cryogenic membrane containment systems for the maritime transportation and storage of liquefied gases, primarily liquefied natural gas (LNG). The company manufactures proprietary membrane technologies including the Mark III, NO96 Max, and GTT Flex systems for LNG carriers, ethane carriers, floating storage units (FSRUs), floating liquefied natural gas units (FLNGs), and LNG bunkering vessels. In addition to cryogenic containment technology, GTT provides engineering, technical assistance, training, digital solutions, and lifecycle support services for shipyards and vessel operators globally. Its portfolio also includes the GTT MARS technology for liquefied petroleum gas (LPG) containment and solutions geared toward LNG as a marine fuel.
Founded in 1994 through a merger of Gaztransport SA and Technigaz SA, GTT is headquartered in Saint-Rémy-lès-Chevreuse, France, and operates worldwide. The company serves maritime and offshore markets focusing on the safe and efficient handling of cryogenic gases. It leverages extensive R&D capabilities, filing numerous patents and maintaining leading technology approvals from classification societies.
Recent major developments include robust revenue growth, reaching €641 million in 2024, a 50% increase year-over-year, driven by a strong order backlog including 68 LNG carriers, 12 ethane carriers, and other specialized vessels. In 2024 and early 2025, GTT secured approvals for its GTT NEXT1 technology, bolstering its competitive position. It also commenced construction of the Elogen Gigafactory, slated to begin production by Q4 2025, expanding its footprint in clean energy technologies. Strategic acquisitions include VPS in early 2024 and Danelec in 2025, focusing on digital solutions for vessel monitoring and management. GTT suspended work with Russia in early 2023 as part of geopolitical risk management. The company continues to innovate in LNG as a fuel and offshore sectors, adapting its technology and services to evolving market demands.
This positions Gaztransport & Technigaz as a global leader in cryogenic membrane solutions for the transport and storage of LNG and other liquefied gases, continuously expanding its technological edge and market reach through innovation and strategic expansion.
