What it means
The category, explained
Gas carriers move methane as a liquid, chilled to minus 162 degrees Celsius so that 600 volumes of gas fit in one volume of tank. Their capacity is quoted in cubic metres of LNG, and the record — 266,000 m³ — belongs to Qatar's Q-Max class, led by Mozah.
The category's outlier is Prelude FLNG: not a carrier but a floating gas factory, moored permanently off Australia, and at 488 metres the largest floating structure humanity has ever built. She appears throughout this site as the asterisk on every length record.
