SATURNUS against its type
Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,800 gross tonnage it is smaller than 92% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 17 chemical tankers here under the Sweden flag, 0.7% of the 2,344 on the register. The same builder is recorded for 40 other vessels here, 32 of them chemical tankers. The returns for 2019–2025 all give Donsö as port of registry.
Its 6,450 t of CO₂ for 2025 is 17% 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 142.2 kg CO₂, 43% below the type median of 250.2 kg. It logged 4,404 hours at sea against a median of 2,109 hours for its type that year. 11.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2020 (8,546 t) and the lowest 2023 (6,236 t). Its efficiency percentile within the type went from 94 in 2019 to 93 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,252 of 1,348 qualifying chemical tankers by EEOI, at the 93rd percentile. The dashed line is the type median, 14.4; this vessel reported 39.7.
EEOI divides emissions by transport work, which for this vessel and year was 162,593,648 tonne-miles over 45,353 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.7% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 3.2% while distance sailed fell 3.8%and CO₂ per nautical mile rose 7.3%.That points mainly to how efficiently it sailed, rather than the other.
