NAVE ARIADNE 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 42,514 gross tonnage it is smaller than 61% of the other 2,841 oil tankers with a recorded tonnage. It is one of 18 oil tankers here under the Cayman Islands flag, 0.5% of the 3,548 on the register. The returns for 2018–2024 all give George Town as port of registry.
Its 4,132 t of CO₂ for 2024 is 50% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 420.6 kg CO₂, close to the type median of 408.2 kg. It logged 848 hours at sea against a median of 2,020 hours for its type that year. 8.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 4 years with reported emissions, the highest was 2020 (8,205 t) and the lowest 2024 (4,132 t). Its efficiency percentile within the type went from 49 in 2018 to 68 in 2024 (lower is more efficient). Of the 5 comparable vessels listed below with a 2024 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 1,067 of 1,566 qualifying oil tankers by EEOI, at the 68th percentile. The dashed line is the type median, 7.6; this vessel reported 9.4.
EEOI divides emissions by transport work, which for this vessel and year was 440,933,831 tonne-miles over 9,822 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 42.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2020 to 2024, emissions fell 49.6% while distance sailed fell 27.1%and CO₂ per nautical mile fell 30.9%.
