DONG-A THETIS 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 62,350 gross tonnage it is larger than 58% 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 461 other vessels here, 179 of them oil tankers. Its MRV returns name it DONG-A THETIS for 2018–2022 and ELANDRA FIRTH for 2025. The reported port of registry changed: Panama (2018–2022), then Monrovia (2025).
Its 10,908 t of CO₂ for 2022 is 1.5 times the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 456.6 kg CO₂, close to the type median of 415.9 kg. It logged 2,339 hours at sea against a median of 1,731 hours for its type that year. 18.1% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2022 (10,908 t) and the lowest 2018 (2,723 t). Its efficiency percentile within the type went from 36 in 2018 to 30 in 2022 (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 type2022
Position 534 of 1,771 qualifying oil tankers by EEOI, at the 30th percentile. The dashed line is the type median, 8.0; this vessel reported 6.3.
EEOI divides emissions by transport work, which for this vessel and year was 1,720,566,246 tonne-miles over 23,889 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 300.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2021 to 2022, emissions rose 26.7% while distance sailed fell 2.4%and CO₂ per nautical mile rose 29.8%.That points mainly to how efficiently it sailed, rather than the other.
