MARLIN AVENTURINE against its type
Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,534 gross tonnage it is smaller than 77% 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 192 other vessels here, 71 of them oil tankers. The returns for 2021–2025 all give MAJURO as port of registry.
Its 6,898 t of CO₂ for 2025 is 13% 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 319.6 kg CO₂, 21% below the type median of 403.2 kg. It logged 1,866 hours at sea against a median of 2,030 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2024 (9,486 t) and the lowest 2019 (1,538 t). Its efficiency percentile within the type went from 48 in 2018 to 84 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,215 of 1,448 qualifying oil tankers by EEOI, at the 84th percentile. The dashed line is the type median, 7.5; this vessel reported 13.6.
EEOI divides emissions by transport work, which for this vessel and year was 507,201,471 tonne-miles over 21,583 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 81.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 27.3% while distance sailed fell 30.3%and CO₂ per nautical mile rose 4.3%.That points mainly to how much the vessel sailed, rather than the other.
