Transported by sea, LNG becomes a flexible global energy source that integrates with the energy transition.
Liquefied natural gas (LNG) is a strategic resource to meet the growing global demand for accessible, secure and flexible energy. Eni operates in this sector by managing a modern fleet equipped with advanced technologies, mainly comprising six vessels: GasLog Italy, Maran Gas Kalymnos and Maran Gas Kastelorizo, Maran Gas Achilles, Maran Gas Delphi and SeaPeak Galicia. Through its subsidiary LNG Shipping S.p.A., we optimise transportation efficiently, reaching key markets along global maritime routes.
LNG is produced by cooling natural gas to very low temperatures (around -160°C) at near atmospheric pressure. This reduces its volume by approximately six hundred times compared to its gaseous state (NG). An LNG carrier can transport a significant amount of liquid gas (between 60,000 and 200,000 cubic metres depending on the vessel type) equivalent to around 36 to 120 million cubic metres of natural gas.
Once at its destination, the LNG is regasified, i.e. converted back to its gaseous form, and fed into the country’s pipeline network to supply homes, industries and power plants.
Unlike fixed international pipelines, LNG transported by ship connects exporting and importing countries via liquefaction and regasification terminals. Overall, LNG improves supply flexibility and market accessibility, both for sourcing and sales, thereby strengthening energy security.
Natural gas is transported through pipelines following fixed routes from production sites to consumption areas.
Natural gas can be shipped by sea via a global network of liquefaction and regasification terminals, where vessels can dock.
Exporter-importer agreements are made on a case-by-case basis according to specific market needs. This multiplies global supply options and enhances overall energy security.

Following the principle of technological neutrality, with diversification of energy sources, we can help to realise the transition to sustainable, secure and affordable energy.
Versatility and accessibility are key to making natural gas an affordable, safe and sustainable source of energy.
A versatile source that complements the ever-changing energy world and one that can play a supporting role in the decarbonisation path.
