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

She was built by Samsung Heavy Industries in South Korea, and delivered to her Norwegian operator Leif Höegh & Co for US$290 million 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).[1] 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.[2]

The vessel has a storage capacity of 145,130 m3 (5,125,000 cu ft). Compared to standard LNG carriers, she has additional features such as three skid-mounted regasification units supplied by Wärtsilä Hamworthy, discharging arrangements, as well as specialized equipment to reduce and contain emissions to air and water during the cargo processing and handling cycle and turret mooring. The hourly capacity of regasification is 210 tons at a send-out pressure of 115 bar (11,500 kPa).[2]

The floating LNG carrier sailed from France to Turkey and moored at a special pier of Egegaz Terminal in Aliağa district of İzmir Province on December 11, 2016. She went in service as Turkey's first floating LNG storage facility on December 23, 2016.[3][4]
