JBU OPAL against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,561 gross tonnage it is smaller than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 15 chemical tankers here under the South Korea flag, 0.6% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. The reported port of registry changed: Majuro (2021), then Jeju (2024–2025).
Its 1,828 t of CO₂ for 2024 is 69% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 354.6 kg CO₂, 40% above the type median of 253.5 kg. It logged 488 hours at sea against a median of 2,177 hours for its type that year. 4.9% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Its efficiency percentile within the type went from 74 in 2021 to 64 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.
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 763 of 1,194 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 15.9; this vessel reported 20.1.
EEOI divides emissions by transport work, which for this vessel and year was 91,010,956 tonne-miles over 5,154 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 22.4% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2021 to 2024, emissions fell 22.4% while distance sailed fell 38.8%and CO₂ per nautical mile rose 26.8%.
