HAFNIA AVENTURINE against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,676 gross tonnage it is larger than 54% 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 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it NAVIG8 AVENTURINE for 2018–2021 and HAFNIA AVENTURINE for 2022–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 6,316 t of CO₂ for 2025 is 14% 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 234.3 kg CO₂, close to the type median of 250.2 kg. It logged 2,493 hours at sea against a median of 2,109 hours for its type that year. 2.7% 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 (10,653 t) and the lowest 2022 (1,915 t). Its efficiency percentile within the type went from 37 in 2018 to 13 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 173 of 1,348 qualifying chemical tankers by EEOI, at the 13th percentile. The dashed line is the type median, 14.4; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 760,102,286 tonne-miles over 26,959 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 40.7% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 14.3% while distance sailed rose 32.4%and CO₂ per nautical mile fell 13.7%.That points mainly to how much the vessel sailed, rather than the other.
