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 realizations

Logistics
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.
