LNG DUBHE against its type
Built in 2019, it is 5 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 113,397 gross tonnage it is larger than 56% of the other 377 LNG carriers with a recorded tonnage. It is one of 16 LNG carriers here under the Hong Kong flag, 3.0% of the 538 on the register. The same builder is recorded for 204 other vessels here, 9 of them LNG carriers. The returns for 2019–2025 all give Hong Kong as port of registry.
Its 13,733 t of CO₂ for 2025 is 36% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 551.5 kg CO₂, close to the type median of 533.6 kg. It logged 2,007 hours at sea against a median of 2,940 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 7 years with reported emissions, the highest was 2020 (52,803 t) and the lowest 2025 (13,733 t). Of the 6 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 3.6% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 60.0% and CO₂ per nautical mile fell 1.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
