AQUARIUS against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,534 gross tonnage it is smaller than 78% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 5 chemical tankers here under the Vietnam flag, 0.2% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. The returns for 2024–2025 all give Sai Gon as port of registry.
Its 7,656 t of CO₂ for 2025 is 38% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 243.6 kg CO₂, close to the type median of 250.2 kg. It logged 2,733 hours at sea against a median of 2,109 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 56 in 2024 to 80 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,082 of 1,348 qualifying chemical tankers by EEOI, at the 80th percentile. The dashed line is the type median, 14.4; this vessel reported 26.9.
EEOI divides emissions by transport work, which for this vessel and year was 284,937,105 tonne-miles over 31,424 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 426.7% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 426.7% while distance sailed rose 479.3%and CO₂ per nautical mile fell 9.1%.That points mainly to how much the vessel sailed, rather than the other.
