BIG: “Shell’s latest fossil-fuel-extracting vehicle will dwarf every U.S. naval ship. The Prelude Floating Liquefied Natural Gas (FLNG) facility will be nearly one-third of a mile long and tip the scales at up to 600,000 tons. That’s six times heavier than the U.S.’ largest aircraft carrier. . . . The Prelude FLNG will be used to extract, cool and offload liquefied natural gas into tankers so that it can be transported to major markets across the world. Until now, the liquefaction of offshore gas has always involved piping the gas to a land-based plant.”
