NAVIS against its type
Built in 2002, it is 11 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 5,286 gross tonnage it is smaller than 99% of the other 525 gas carriers with a recorded tonnage. It is the only gas carrier on this register under the Vietnam flag. Its MRV returns name it TAMARA for 2018–2019 and NAVIS for 2024–2025. The reported port of registry changed: Panama (2018–2019), then HAI PHONG (2024–2025).
Its 2,543 t of CO₂ for 2025 is 57% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 151.5 kg CO₂, 41% below the type median of 256.2 kg. It logged 1,492 hours at sea against a median of 1,943 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 4 years with reported emissions, the highest was 2024 (4,563 t) and the lowest 2025 (2,543 t). Its efficiency percentile within the type went from 59 in 2018 to 86 in 2024 (lower is more efficient). Of the 5 comparable vessels 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 26.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 44.3% and CO₂ per nautical mile fell 2.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
