PROMETHEUS ENERGY against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 63,500 gross tonnage it is larger than 65% 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 103 other vessels here, 28 of them oil tankers. The returns for 2019–2025 all give Majuro as port of registry.
Its 18,556 t of CO₂ for 2025 is 2.3 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 392.8 kg CO₂, close to the type median of 403.2 kg. It logged 5,564 hours at sea against a median of 2,030 hours for its type that year. 20.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2022 (23,335 t) and the lowest 2019 (9,198 t). Its efficiency percentile within the type went from 30 in 2019 to 70 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,020 of 1,448 qualifying oil tankers by EEOI, at the 70th percentile. The dashed line is the type median, 7.5; this vessel reported 9.7.
EEOI divides emissions by transport work, which for this vessel and year was 1,916,929,752 tonne-miles over 47,236 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 101.7% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 10.5% while distance sailed rose 22.8%and CO₂ per nautical mile fell 10.1%.That points mainly to how much the vessel sailed, rather than the other.
