ORIENTAL ACACIA against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 7,785 gross tonnage it is smaller than 89% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 48 chemical tankers here under the Cayman Islands flag, 2.0% of the 2,344 on the register. The returns for 2018–2025 all give GEORGE TOWN as port of registry.
Its 9,129 t of CO₂ for 2025 is 1.6 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 203.2 kg CO₂, 19% below the type median of 250.2 kg. It logged 3,968 hours at sea against a median of 2,109 hours for its type that year. 16.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (18,071 t) and the lowest 2022 (8,848 t). Its efficiency percentile within the type went from 97 in 2018 to 81 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,096 of 1,348 qualifying chemical tankers by EEOI, at the 81st percentile. The dashed line is the type median, 14.4; this vessel reported 27.5.
EEOI divides emissions by transport work, which for this vessel and year was 332,327,630 tonne-miles over 44,935 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 26.5% while distance sailed fell 19.1%and CO₂ per nautical mile fell 9.2%.That points mainly to how much the vessel sailed, rather than the other.
