The largest LNG tankers in existence with a 210,000 (Q-Flex) and 266,000 (Q-Max) cubic meter LNG capacity. Qatar Gas Transport Co ordered and will operate the first “Q-Max” having the capacity to carry 266,000 cu m of LNG, almost 80% more cargo than conventional LNG ships. Named the Mozah, it has a length of 345 m, a breadth of 53.8 m, and a height of 34.71 m. Designated as “Q-Max”: Q for Qatar and Max for the maximum-size ship able to dock at that country’s LNG terminals, the new vessels are expected to spearhead long-haul gas shipping to the US and Europe. The Q-Max vessels feature slow-speed diesel engines that are more fuel and thermal-efficient than steam turbines with a 30% reduction in overall emissions. Improved economies of scale inherent in the much larger comparative load capacity also are expected to reduce shipping costs by 30%. Shipping by conventional vessels typically accounts for a third of the LNG price
