SALTSTRAUM against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 7,256 gross tonnage it is smaller than 91% 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 160 other vessels here, 8 of them chemical tankers. The returns for 2020–2025 all give Bergen as port of registry.
Its 7,844 t of CO₂ for 2025 is 42% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 152.9 kg CO₂, 39% below the type median of 250.2 kg. It logged 4,756 hours at sea against a median of 2,106 hours for its type that year. 11.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (8,875 t) and the lowest 2020 (4,140 t). Its efficiency percentile within the type went from 85 in 2020 to 87 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,178 of 1,348 qualifying chemical tankers by EEOI, at the 87th percentile. The dashed line is the type median, 14.4; this vessel reported 33.6.
EEOI divides emissions by transport work, which for this vessel and year was 233,186,980 tonne-miles over 51,314 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 89.5% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.7% while distance sailed fell 3.9%and CO₂ per nautical mile rose 0.2%.That points mainly to how much the vessel sailed, rather than the other.
