Not reported

Identified from the containment system and engine recorded against the ship, and from firms named on it in our curated list.

Designs the high-pressure ME-GI and low-pressure ME-GA two-stroke dual-fuel engines used to propel LNG carriers on boil-off gas.

Stakes exactly as GEM reports them for this vessel.

Vessels from the same yard, delivered the same year, with the same cargo capacity to the nearest 1,000 m³. A shared design is likely but not certain.

Background on the technology and the terms used on this page.

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.
Propulsion III: ME-GI, X-DF and two-stroke gas injection
ME-GI and X-DF are the two families of low-speed two-stroke marine engine burning natural gas, differing in whether gas is injected at high pressure late in the cycle or admitted at low pressure and premixed.
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.
Boil-off and reliquefaction
Boil-off is the small fraction of an LNG cargo that evaporates each day as heat leaks into the tanks, and it is what keeps the rest of the cargo cold.
