YUAN DONG HAI against its type
Built in 2020, it is 10 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 84,127 gross tonnage it is larger than 83% of the other 2,841 oil tankers with a recorded tonnage. It is one of 30 oil tankers here under the China flag, 0.8% of the 3,548 on the register. The same builder is recorded for 146 other vessels here, 55 of them oil tankers. The returns for 2020–2025 all give YANGPU CHINA as port of registry.
Its 20,543 t of CO₂ for 2025 is 2.6 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 412.5 kg CO₂, close to the type median of 403.2 kg. It logged 5,129 hours at sea against a median of 2,030 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (20,543 t) and the lowest 2022 (3,914 t). Its efficiency percentile within the type went from 13 in 2020 to 20 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 291 of 1,448 qualifying oil tankers by EEOI, at the 20th percentile. The dashed line is the type median, 7.5; this vessel reported 5.2.
EEOI divides emissions by transport work, which for this vessel and year was 3,950,507,692 tonne-miles over 49,805 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 133.1% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 13.9% while distance sailed rose 20.2%and CO₂ per nautical mile fell 5.3%.That points mainly to how much the vessel sailed, rather than the other.
