Built in 1994, the South Korean flagged YK Sovereign is 274m long with a deadweight tonnage of 72,020 tonnes.

Most LNG carriers can be identified by two distinct types of tank construction – the ‘Moss-type’ with spherical tanks, and the membrane-type with the tanks built into the ship.

The first LNG carrier with spherical tanks, the Kvaerner-Moss System, was the Norman Lady launched in Stavanger, Norway in 1973.

The membrane-type ships were developed during the 1960s, and use a thin flexible metal ‘membrane’ that is in contact with the ship’s cargo.

Until 2000, 54 per cent of all LNG carriers were spherical, primarily because Japanese shipyards had a license for the construction of this type of ship only.

Currently, ships with membrane tanks have outnumbered the traditional spherical or ‘Moss-type’ LNG carriers.
The YK Sovereign departed the Port of Gladstone on 16 April 2016 bound for Korea.

The three LNG plants on Curtis Island will continue to ramp-up their production in 2016 and will add over 25 million tonnes of trade through the Port of Gladstone each year.
