A typical LNG carrier has four to six tanks located along the center-line of the vessel. Surrounding the tanks is a combination of ballast tanks, cofferdams and voids; in effect, this gives the vessel a double-hull type design. LNG carriers, like aircraft carriers, are among the most difficult vessels to build, taking as long as 30 months. [24]
Q-Max is a type of ship, specifically a membrane type LNG carrier. In the name Q-Max, "Q" stands for Qatar and "Max" for the maximum size of ship able to dock at the Liquefied natural gas (LNG) terminals in Qatar. Ships of this type are the largest LNG carriers in the world. [1] [10]
Compressed natural gas (CNG) carrier ships are those designed for transportation of natural gas under high pressure. [1] CNG carrier technology relies on high pressure, typically over 250 bar (2900 psi ), to increase the density of the gas, but it is still 2.4 times less than that of LNG (426 kg/m 3 ). [ 2 ]
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.
LNG carrier A liquefied natural gas ship at Świnoujście LNG terminal in Poland. Liquefied natural gas (LNG) is natural gas (predominantly methane, CH 4, with some mixture of ethane, C 2 H 6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.
LNG El Paso Sonatrach was a liquefied natural gas carrier (LNG) of the El Paso Marine Corporation which was active in the late 1970s. Although she was US owned, the ship was registered in Liberia because of tax and economical reasons.
This liquefied condition is used to facilitate the carriage of natural gas over long distances, often by sea, in specialized tanks. LNG port terminals are purpose-built port terminals designed to accommodate large LNG carrier ships designed to load, carry and unload LNG. These LNG terminals are located adjacent to a gas liquefaction and storage ...
Gas carriers built between 1976 and 1986 (the GC Code) The regulations covering gas carriers built after 1976 but before July 1986 are included in the Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk. It is known as the Gas Carrier Code or GC Code in short.
