Efficacité comparative du transport maritime de gaz naturel.

Comparative efficiency of natural gas sea transportation.

Auteurs : ODISHARIYA G., IZOTOV N.

Résumé

The paper describes different variants of natural gas transportation: in liquefied state (liquefied natural gas - LNG); in gaseous state under high pressure (compressed natural gas - CNG); using adsorption and absorption processes; in the form of gas hydrate. According to the results of analysis of the above variants, one can conclude that each variant has its own scope of efficient application in terms of volume and distance of transportation. LNG variant is the most efficient for long-distance (over 3000 km) transportation of large volumes of gas. At present some companies have developed several CNG vessel projects, while other companies are planning to transport refrigerated (to -30/-40°C) compressed gas. By the authors' calculations, such technology is effective only for small (up to 3 bcm/y) volumes of gas supplied on short distances (up to 2000 km). The same situation is with the other types of gas transportation.
