BOW AQUARIUS against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 26,364 gross tonnage it is larger than 62% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 95 chemical tankers here under the Norway flag, 4.1% of the 2,344 on the register. The same builder is recorded for 118 other vessels here, 7 of them chemical tankers. The returns for 2018–2025 all give Bergen as port of registry.
Its 8,973 t of CO₂ for 2025 is 1.6 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 323.9 kg CO₂, 29% above the type median of 250.2 kg. It logged 2,109 hours at sea against a median of 2,106 hours for its type that year. 9.3% 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 (10,057 t) and the lowest 2022 (2,922 t). Its efficiency percentile within the type went from 21 in 2018 to 35 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 468 of 1,348 qualifying chemical tankers by EEOI, at the 35th percentile. The dashed line is the type median, 14.4; this vessel reported 11.9.
EEOI divides emissions by transport work, which for this vessel and year was 755,929,233 tonne-miles over 27,705 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 173.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 32.3% while distance sailed rose 21.6%and CO₂ per nautical mile rose 8.7%.That points mainly to how much the vessel sailed, rather than the other.
