Fuel lifecycle climate warming impact. When comparing the CO2-equivalent emissions of different fuels per 1 tonne of cargo transported 1 km by ship, the climate warming of LNG exceeds that of heavy fuel oil when the amount of methane slip from LNG use is greater than approximately 1% of the volume of LNG.
LNG & Marine Shipping: LNG ships are made with many safety features. These include insulated tanks and double hulls. The LNG tanks can be rectangular or round, spherical in modern LNG carriers.
The lifecycle of LNG involves extraction from the ground, removal of impurities and gases and then it is shipped through a pipeline to a liquefaction facility and stored in an LNG tank for shipping. It’s processed upon arrival.
