NAVIGATOR GEMINI against its type
Built in 2009, it is 4 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 18,311 gross tonnage it is smaller than 60% 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 983 other vessels here, 64 of them gas carriers. The returns for 2018–2023 all give Monrovia as port of registry.
Its 4,054 t of CO₂ for 2023 is 29% below the median of 5,702 t among the 338 gas carriers on this register that reported for 2023. Per nautical mile it emitted 417.3 kg CO₂, 1.6 times the type median of 262.3 kg. It logged 981 hours at sea against a median of 1,868 hours for its type that year. 3.8% of its 2023 emissions were at berth; the median for gas carriers was 4.5%. Across 5 years with reported emissions, the highest was 2018 (13,906 t) and the lowest 2019 (3,605 t). Its efficiency percentile within the type went from 48 in 2018 to 93 in 2022 (lower is more efficient). The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2023 was 70.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2022 to 2023, emissions fell 23.1% and CO₂ per nautical mile rose 38.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
