ORWELL against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 29,727 gross tonnage it is larger than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it ORWELL for 2018–2021, UOG SYROS for 2022–2023 and ORWELL for 2025. The reported port of registry changed: Majuro (2018–2023), then Monrovia (2025).
Its 3,974 t of CO₂ for 2023 is 26% below the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 341.7 kg CO₂, 32% above the type median of 258.0 kg. It logged 909 hours at sea against a median of 1,919 hours for its type that year. 9.7% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 6 years with reported emissions, the highest was 2021 (9,856 t) and the lowest 2023 (3,974 t). Its efficiency percentile within the type went from 78 in 2018 to 17 in 2023 (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 type2023
Position 213 of 1,230 qualifying chemical tankers by EEOI, at the 17th percentile. The dashed line is the type median, 15.6; this vessel reported 10.0.
EEOI divides emissions by transport work, which for this vessel and year was 396,607,784 tonne-miles over 11,632 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 43.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2022 to 2023, emissions fell 46.6% while distance sailed fell 49.7%and CO₂ per nautical mile rose 6.3%.That points mainly to how much the vessel sailed, rather than the other.
