Our mission

Air Liquide Maritime aims at developing gas usages for the actors in the maritime sector, such as:

  • Offshore oil and gas platforms (construction and maintenance, inerting, support to drilling, analytical services, diving gases), drilling vessels, Floating Production or Storage Units (FPUs/ FSUs) and offshore wind turbines
  • Solutions for logistics and cryogenic transport by sea of high value-added molecules, such as helium, argon, carbon dioxide or Liquefied Natural Gas (LNG)

Air Liquide Maritime has a strong customer focus, agile teams and an entrepreneurial spirit that allow it to fully contribute to incubating new activities.

Our organization

Present in


As part of Global Markets & Technologies, which focuses on new markets requiring a global approach, Air Liquide Maritime’s international organization covers around 30 countries.

Our realizations

Cryogenic container.


Our logistic activity gathers all our services of cryogenic transportation of molecules, including high value-added molecules: helium, argon, carbon dioxide and Liquefied Natural Gas (LNG).

Our logistic services are adaptable to our customers’ needs, from rental of ISO containers to door-to-door transportation. We offer multimodal transportation services, involving in particular maritime transport.

Our fleet has more than 1,300 containers, available for our various logistic activities and covering the entire world. The presence of Air Liquide in 80 countries leverages our logistic capacities.

On the cutting edge of technology, our containers allow us to transport effectively high value-added molecules such as helium at temperatures close to absolute zero. The temperature is maintained at a lowest level during transport thanks to a liquid nitrogen layer. Our containers rely on Air Liquide’s expertise in cryogenic technologies and ensure a secure and reliable supply.

Combined with our advanced planning software, our tracking system allows real-time tracking of our containers, in particular for helium. It contributes to the efficiency of our logistic activity and enables us to inform our clients perfectly of the geolocation of the containers.

Our containers are also equipped with connected sensors in order to control permanently main parameters such as temperature and pressure, enabling us to optimize our supply chain.

Focus on


Today, Air Liquide is the leader of the helium worldwide market.

Helium is used in numerous industrial sectors, including medical equipment (MRI), electronics, aerospace engineering, fiber optics and welding.

Although helium is the second most abundant gas in the universe, it is relatively rare on the earth and thus considered as one of the most precious elements.

Helium is a colorless, odorless, non-flammable, inert gas. Along with argon, krypton, xenon and neon, which share similar properties, helium is classified as a noble gas (or rare gas). Helium has the lowest boiling point of all elements (-269°C).

Helium is sourced from natural gas fields and is extracted during the natural gas liquefaction process. Air Liquide is present along the entire supply chain, from extraction to distribution.

Worldwide transport and distribution of helium

Helium from several sources around the world is transferred by maritime transport to Air Liquide centers. The precious gas is then distributed to the clients of the Group. Our containers, transporting 36,000 liters of liquefied helium at -270°C, are equipped with a GPS tracking system developed by Air Liquide. They constitute one of the most important fleets of helium containers with a fully digitalized piloting. In addition, Air Liquide now operates the world’s first pure helium storage facility, located in Germany.

On the rare gases market, Air Liquide is also world leader for xenon.

Discover helium

Health, telecommunications, deep-sea diving, space exploration, etc. The modern world depends on helium. Air Liquide's cutting-edge technology makes us a major supplier of this essential gas.
