GASCHEM ANTARCTIC against its type
Built in 2010, it is 3 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 13,879 gross tonnage it is smaller than 71% of the other 525 gas carriers with a recorded tonnage. It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. The same builder is recorded for 65 other vessels here, 10 of them gas carriers. Its MRV returns name it GASCHEM ANTARCTIC for 2018–2023 and NAVIGATOR TITAN for 2025. The returns for 2018–2025 all give Monrovia as port of registry.
Its 5,974 t of CO₂ for 2025 is close to the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 204.7 kg CO₂, 20% below the type median of 256.2 kg. It logged 2,287 hours at sea against a median of 1,943 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 7 years with reported emissions, the highest was 2018 (16,965 t) and the lowest 2022 (761 t). Its efficiency percentile within the type went from 61 in 2018 to 63 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 185 of 292 qualifying gas carriers by EEOI, at the 63rd percentile. The dashed line is the type median, 27.9; this vessel reported 38.7.
EEOI divides emissions by transport work, which for this vessel and year was 154,435,884 tonne-miles over 29,182 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 64.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 288.0% while distance sailed rose 419.2%and CO₂ per nautical mile fell 25.3%.That points mainly to how much the vessel sailed, rather than the other.
