AS ORELIA against its type
It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it AS ORELIA for 2018–2019 and ORCHID KEFALONIA for 2021–2024. The reported port of registry changed: Manila (2018–2019), then Majuro (2021–2024).
Its 4,109 t of CO₂ for 2024 is 30% 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 199.3 kg CO₂, 21% below the type median of 253.5 kg. It logged 1,796 hours at sea against a median of 2,177 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 6 years with reported emissions, the highest was 2018 (7,208 t) and the lowest 2019 (2,455 t). Its efficiency percentile within the type went from 67 in 2018 to 37 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 455 of 1,230 qualifying chemical tankers by EEOI, at the 37th percentile. The dashed line is the type median, 15.6; this vessel reported 13.3.
EEOI divides emissions by transport work, which for this vessel and year was 266,402,715 tonne-miles over 18,098 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 43.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2023 to 2024, emissions rose 16.3% and CO₂ per nautical mile rose 2.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
