Q-Max is a type of ship, specifically a membrane type liquefied natural gas carrier. It is the type of the largest LNG carriers in the world.[2][3] In the name Q-Max, "Q" stands for Qatar and "Max" for the maximum size of ship able to dock at the LNG terminals in Qatar.
Technical description
Q-Max is 345 metres (1,132 ft) long and measures 53.8 metres (177 ft) wide and 34.7 metres (114 ft) high.[3] It has a capacity of 266,000 m3.[4] It is propelled by two slow speed diesel engines, which are claimed to be more efficient and environmentally friendly than traditional steam turbines.[5] Q-Max vessels are equipped with an on-board re-liquefaction system to handle the boil-off gas, liquefy it and return the LNG to the cargo tanks.[6] The on-board re-liquefaction system allows a reduction of LNG losses, which produces economical and environmental benefits. Overall, it is estimated that Q-Max carriers have about 40% lower energy requirements and carbon emissions than conventional LNG carriers.[4][7]
Contractors
Q-Max LNG carriers were ordered in 2005.[3] They are to be built by Samsung Heavy Industries and Daewoo Shipbuilding & Marine Engineering Company.[3][4] The installed Boil Off Gas re-liquefaction system (Ecorel) is developed and delivered by Cryostar and approved and certified by LR.[8]
Ships
The first Q-Max LNG carrier was floated out of dry-dock in November 2007.[7] The naming ceremony was held on 11 July 2008 at Samsung Heavy Industries' shipyard on Geoje Island, South Korea.[2] Known before its naming ceremony as Hull 1675, the ship was named Mozah by Her Highness Sheikha Mozah Nasser al-Misnad.[9] Mozah was delivered on 29 September 2008.[9][10] It is classed by Lloyd's Register.[2] She transited the Suez Canal for the first time on April 30th, 2009,[11] and docked at South Hook LNG terminal in Pembroke Dock, Milford Haven, Wales on May 7th, 2009.[12]
Q-Max LNG carriers are ordered by, and to be operated by the Qatar Gas Transport Company (Nakilat), and would be chartered to Qatar's LNG producers Qatargas and RasGas.[2] In total, contracts have been signed for the construction of 14 Q-Max vessels.[13]
