Golar Tundra

• Porto Torres FSRU · Italy

Global Energy Monitor names this vessel on the terminal's units. The terminal and carrier workbooks share no identifier, so the link is made by an exact name match and only where the name belongs to one tracked vessel.

• LNG carrier anatomy

  An LNG carrier is a ship built around insulated cargo tanks that hold liquefied gas at minus 162 degrees, with an engine able to burn the cargo vapour that inevitably boils off during the voyage.

• Membrane versus Moss tanks

  Cargo containment is the system that holds LNG at minus 162 degrees inside a ship, and it comes in two families: membranes, which are thin barriers supported by the hull, and free-standing tanks, which carry their own load.

• Propulsion II: DFDE and TFDE, the dual-fuel era

  Dual-fuel diesel electric propulsion uses medium-speed engines burning either boil-off gas or liquid fuel to generate electricity, which drives electric propulsion motors rather than a directly coupled shaft.

• Ship classes: conventional, Q-Flex, Q-Max and small-scale

  LNG carriers fall into recognised size classes running from small-scale vessels under 30,000 cubic metres, through the 174,000 cubic metre conventional standard, to the 266,000 cubic metre Q-Max ships built for Qatar.
