AIGRAN D against its type
Built in 1997, it is 13 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,875 gross tonnage it is smaller than 92% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 15 chemical tankers here under the Netherlands flag, 0.6% of the 2,344 on the register. The same builder is recorded for 8 other vessels here, 6 of them chemical tankers. Its MRV returns name it AIGRAN D for 2018–2021 and NQ CALIPSO for 2022–2024. The returns for 2018–2024 all give Rotterdam as port of registry.
Its 8,741 t of CO₂ for 2024 is 50% above the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 191.6 kg CO₂, 24% below the type median of 253.5 kg. It logged 5,621 hours at sea against a median of 2,177 hours for its type that year. 6.4% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2024 (8,741 t) and the lowest 2019 (886 t). Its efficiency percentile within the type went from 86 in 2020 to 90 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 1,072 of 1,194 qualifying chemical tankers by EEOI, at the 90th percentile. The dashed line is the type median, 15.9; this vessel reported 39.0.
EEOI divides emissions by transport work, which for this vessel and year was 224,362,680 tonne-miles over 45,632 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 509.2% higher than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 19.1% while distance sailed rose 12.1%and CO₂ per nautical mile rose 6.2%.That points mainly to how much the vessel sailed, rather than the other.
