ATLANTAS against its type

Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 162,198 gross tonnage it is larger than 96% 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 same builder is recorded for 660 other vessels here, 159 of them oil tankers. Its MRV returns name it BASRA for 2018–2019 and ATLANTAS for 2022–2025. The returns for 2018–2025 all give Monrovia as port of registry.

Its 4,900 t of CO₂ for 2024 is 40% 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 629.1 kg CO₂, 1.5 times the type median of 408.2 kg. It logged 733 hours at sea against a median of 2,020 hours for its type that year. 11.5% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 5 years with reported emissions, the highest was 2023 (24,086 t) and the lowest 2024 (4,900 t). Its efficiency percentile within the type went from 45 in 2018 to 79 in 2024 (lower is more efficient).

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024

Position 1,242 of 1,566 qualifying oil tankers by EEOI, at the 79th percentile. The dashed line is the type median, 7.6; this vessel reported 11.4.

EEOI divides emissions by transport work, which for this vessel and year was 431,321,303 tonne-miles over 7,788 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2024 was 34.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2023 to 2024, emissions fell 79.7% while distance sailed fell 74.3%and CO₂ per nautical mile fell 20.8%.That points mainly to how much the vessel sailed, rather than the other.
