PATMOS I against its type
Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 82,605 gross tonnage it is larger than 79% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2018–2025 all give Monrovia as port of registry.
Its 4,024 t of CO₂ for 2025 is 49% 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 464.4 kg CO₂, 15% above the type median of 403.2 kg. It logged 852 hours at sea against a median of 2,030 hours for its type that year. 14.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2023 (6,462 t) and the lowest 2018 (1,285 t). Its efficiency percentile within the type went from 37 in 2018 to 5 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 76 of 1,448 qualifying oil tankers by EEOI, at the 5th percentile. The dashed line is the type median, 7.5; this vessel reported 3.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,039,834,625 tonne-miles over 8,665 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 213.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2023 to 2025, emissions fell 37.7% while distance sailed fell 46.1%and CO₂ per nautical mile rose 15.6%.That points mainly to how much the vessel sailed, rather than the other.
