MT GDF Suez Neptune is a liquefied natural gas (LNG) carrier, which is currently used as a floating production storage and offloading (FSRO) vessel for LNG at a terminal in Aliağa district of İzmir Province, western Turkey.


She was built by Samsung Heavy Industries in South Korea costing US$290 million.[1] The vessel is owned by French multinational electric utility company GDF Suez.[2] She was delivered to the Norwegian operator Leif Höegh & Co on November 30, 2009. The vessel is 283.06 m (928 ft 8 in) long, has a beam of 43.40 m (142 ft 5 in) and a draft of 11.40 m (37 ft 5 in).[3] At 80,986 DWT, she has a service speed of 19.5 knots (36.1 km/h; 22.4 mph). The vessel is powered by four Wärtsilä dual-fuel-electric LNG engines of Finland, which drive fully integrated four ABB A/S generators from Sweden.[1]

The vessel has a storage capacity of 145,130 m3 (5,125,000 cu ft). Compared to standard LNG carriers, the floating production storage and offloading (FSRO) vessel for LNG has additional features such as three Wärtsilä-Hamworthy supplied regasification units mounted on skids, discharging arrangements, as well as special equipment for reducing emission to air and water. The hourly capacity of regasification is 210 tons at a send-out pressure of 115 bar (11,500 kPa).[1]
