BARBOUNI 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 11,757 gross tonnage it is smaller than 73% 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 52 other vessels here, 48 of them chemical tankers. The returns for 2022–2025 all give Majuro as port of registry.
Its 4,027 t of CO₂ for 2025 is 27% 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 260.0 kg CO₂, close to the type median of 250.2 kg. It logged 1,507 hours at sea against a median of 2,109 hours for its type that year. 10.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2024 (6,042 t) and the lowest 2022 (1,540 t). Its efficiency percentile within the type went from 55 in 2024 to 63 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 845 of 1,348 qualifying chemical tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 14.4; this vessel reported 17.8.
EEOI divides emissions by transport work, which for this vessel and year was 225,835,670 tonne-miles over 15,485 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 161.5% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 33.4% while distance sailed fell 42.1%and CO₂ per nautical mile rose 15.0%.That points mainly to how much the vessel sailed, rather than the other.
