The on-board re-liquefaction system reduces LNG losses, which produces economic and environmental benefits. Overall, it is estimated that Q-Flex carriers have about 40% lower energy requirements and carbon emissions than conventional LNG carriers. [4] The capacity of a Q-Flex vessel is between 165,000 m 3 and 216,000 m 3. [5]
The Q-Max LNG carriers were ordered in 2005. [10] They were built by Samsung Heavy Industries and Daewoo Shipbuilding & Marine Engineering. [10] [16] The installed Boil Off Gas re-liquefaction system (Ecorel) is developed and delivered by Cryostar, and approved and certified by Lloyds Register. [19] A Moss-type (not Q-Max type) LNG tanker, side ...
The size and capacity of LNG carriers has increased significantly, [8] to 170,000 cubic metres (6,000,000 cu ft). A vessel could cost $200 million. [7] Since 2005, Qatargas has pioneered the development of two new classes of LNG carriers, referred to as Q-Flex and Q-Max. Each ship has a cargo capacity of between 210,000 and 266,000 cubic metres ...
A liquefied natural gas terminal is a facility for managing the import and/or export of liquefied natural gas (LNG). It comprises equipment for loading and unloading of LNG cargo to/from ocean-going tankers , for transfer across the site, liquefaction, re-gasification, processing, storage, pumping, compression, and metering of LNG.

The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
Mozah is a Q-Max LNG carrier operated by Qatargas II. The vessel was built in 2008 by Samsung Heavy Industries and is tied with her sister ships for the largest LNG carrier in the world. [1] The vessel is part of a contract for 14 same-size ships with maximum particulars to berth at Ras Laffan terminal in Qatar.
A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. Due to natural gas' cleaner burning properties, the use of natural gas in merchant ship propulsion plants is becoming an option for companies in order to comply with IMO and MARPOL environmental regulations.
Gaztransport & Technigaz SA is a French multinational naval engineering company with headquarters in Saint-Rémy-lès-Chevreuse, France.. Trading as the GTT Group, the company is an engineering organization specializing in membrane containment systems dedicated to the transport and storage of liquefied gas worldwide.
