The 12 countries that currently export LNG have approximately 28 percent of world natural gas reserves. Three countries with 33 percent of the world’s reserves are currently building their first liquefaction facilities. At least seven additional countries, with 19 % of the world’s reserves, are potential LNG exporters.

Traditional steam turbine powered LNG of 135 - 145 tm3 is virtually a thing of the past
The majority of new ships currently being specified are
– 210-217 tm3 with low speed diesel and on board reliquefaction
– 150-180 tm3 with dual fuel diesel electric propulsion
Forecast 2006 - 2011
– Steam 19 vessels (14%) 76 compressors
– Dual fuel 69 vessels (50%) 276 compressors
– Reliquefaction 51 vessels (36%) 306 compressors
