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. The vessel is owned by French multinational electric utility company GDF Suez. 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). 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.
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).
The vessel sailed to Turkey after loading a full cargo at Montoir LNG Terminal in France, and took position at a special pier of Egegaz LNG Terminal in Aliağa district of İzmir Province on December 11, 2016. French Engie (formerly GDF Suez) and Turkish construction companies Kolin and Kalyon inaugurated the Etki LNG Terminal in Aliağa, where the FSRO went in service as Turkey's first floating liquified natural gas storage facility on December 23, 2016.
