Ambient temperature

Environmental temperature that is not affected by other heat sources.


The “boiling point” is the temperature at which a liquid boils or at which it converts from a liquid to a vapour or gas at atmospheric pressure.  The boiling point of LNG varies with its basic composition, but typically is -162°C .

Calorific value

The quantity of heat produced by the complete combustion of a fuel.

Fossil fuel 

Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years. Fossil fuels include coal, petroleum and natural gas.


A network of pipelines through which gas is transported.

Import terminal

A facility that has the capability of accepting and storing LNG  transported by ship.


In order to obtain maximum volume reduction, natural gas is liquefied by cooling it to a very low temperature (162 °C).

LNG (Liquefied natural gas)

An odourless, colourless, non-corrosive and non-toxic product of natural gas in liquid form at near atmospheric pressure.

LNG value chain

In planning, funding and executing an LNG project, each element of the complex chain that links the natural gas in the ground to the ultimate consumer  is considered. The main elements are natural gas production, liquefaction, shipping, receiving terminal (including regasification), distribution of the regasified LNG and, lastly, consumption of the gas.


The process of warming LNG until liquid gas returns to a gaseous state.

Regasification terminal

At facility at which LNG carriers deliver the LNG. LNG is then stored before undergoing regasification, which converts the LNG back into its gaseous form.
