From Gas fields to Engines
In the liquefaction terminal, the gas is cooled to -162⁰C (methane boiling point) and then it is transmitted from cryogenic tanks into methane carriers. The biggest vessel of this kind, Q-max, loads up to 266 thousand cubic metres of gas, slightly smaller ones – such as Q-flex which will transport LNG to Świnoujście may carry – 216 thousand cubic metres. Ships from ports in the Arabian Peninsula, Malaysia, Indonesia, Algeria or Australia deliver LNG to Korea, India and Europe. Main transport routes go through the Indian Ocean and the Atlantic Ocean and across the Mediterranean Sea to reach Europe. Shipment from Alaska is directed to Japan across the Pacific Ocean. New routes are established as well, such as the one across the Arctic Ocean: where the Ob River methane carrier sailed from Norway to Japan accompanied by Russian nuclear-powered icebreakers last year.
Having reached the regasification terminal, LNG is unloaded to large tanks, then transferred to regasification facility where it is heated and transformed into gaseous state and subsequently injected in the gas pipeline network. It can also be transported in cisterns by road or rail to smaller LNG stations.
