NAVE EQUINOX against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 30,119 gross tonnage it is smaller than 70% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 96 other vessels here, 19 of them oil tankers. Its MRV returns name it NAVE EQUINOX for 2018–2024 and ZONDAR for 2025. The returns for 2019–2025 all give Majuro as port of registry.
Its 4,805 t of CO₂ for 2025 is 39% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 316.8 kg CO₂, 21% below the type median of 403.2 kg. It logged 1,317 hours at sea against a median of 2,030 hours for its type that year. 4.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (16,759 t) and the lowest 2025 (4,805 t). Its efficiency percentile within the type went from 44 in 2018 to 76 in 2024 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 1,190 of 1,566 qualifying oil tankers by EEOI, at the 76th percentile. The dashed line is the type median, 7.6; this vessel reported 10.5.
EEOI divides emissions by transport work, which for this vessel and year was 476,285,850 tonne-miles over 14,981 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 71.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.2% and CO₂ per nautical mile fell 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
