UMM BAB against its type

Built in 2005, it is 9 years older than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 97,496 gross tonnage it is smaller than 84% of the other 377 LNG carriers with a recorded tonnage. It is one of 41 LNG carriers here under the Greece flag, 7.6% of the 538 on the register. The same builder is recorded for 660 other vessels here, 109 of them LNG carriers. The returns for 2018–2025 all give Piraeus as port of registry.

Its 21,593 t of CO₂ for 2025 is close to the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 1,028.7 kg CO₂, 1.9 times the type median of 533.6 kg. It logged 1,435 hours at sea against a median of 2,940 hours for its type that year. 0.2% 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 (65,891 t) and the lowest 2024 (20,571 t). Of the 3 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 61.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions rose 5.0% and CO₂ per nautical mile rose 21.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
