DONG-A MAIA 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 MAIA for 2018–2022 and ELANDRA GULF for 2024–2025. The reported port of registry changed: Panama (2018–2022), then Monrovia (2024–2025).
Its 9,238 t of CO₂ for 2025 is 17% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 418.2 kg CO₂, close to the type median of 403.2 kg. It logged 1,888 hours at sea against a median of 2,030 hours for its type that year. 8.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2020 (23,371 t) and the lowest 2022 (5,980 t). Its efficiency percentile within the type went from 37 in 2018 to 16 in 2025 (lower is more efficient). Of the 7 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 230 of 1,448 qualifying oil tankers by EEOI, at the 16th percentile. The dashed line is the type median, 7.5; this vessel reported 4.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,896,885,010 tonne-miles over 22,090 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 6.4% while distance sailed rose 8.5%and CO₂ per nautical mile fell 1.9%.That points mainly to how much the vessel sailed, rather than the other.
