AS OMARIA against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,570 gross tonnage it is smaller than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 17 other vessels here, 14 of them chemical tankers. Its MRV returns name it AS OMARIA for 2018–2020 and EASTERLY AS OMARIA for 2021–2025. The reported port of registry changed: Manila (2018–2020), then Majuro (2021–2025).
Its 4,102 t of CO₂ for 2025 is 26% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 182.3 kg CO₂, 27% below the type median of 250.2 kg. It logged 1,823 hours at sea against a median of 2,109 hours for its type that year. 3.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (10,023 t) and the lowest 2022 (766 t). Its efficiency percentile within the type went from 82 in 2018 to 54 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 734 of 1,348 qualifying chemical tankers by EEOI, at the 54th percentile. The dashed line is the type median, 14.4; this vessel reported 15.4.
EEOI divides emissions by transport work, which for this vessel and year was 266,539,311 tonne-miles over 22,505 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 20.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 116.7% while distance sailed rose 143.3%and CO₂ per nautical mile fell 11.0%.That points mainly to how much the vessel sailed, rather than the other.
