MOSTRAUM 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 7,231 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 40 other vessels here, 32 of them chemical tankers. The returns for 2019–2025 all give Bergen as port of registry.
Its 7,593 t of CO₂ for 2025 is 37% 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 134.4 kg CO₂, 46% below the type median of 250.2 kg. It logged 5,050 hours at sea against a median of 2,106 hours for its type that year. 15.1% 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 (10,290 t) and the lowest 2019 (5,222 t). Its efficiency percentile within the type went from 84 in 2019 to 85 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,144 of 1,348 qualifying chemical tankers by EEOI, at the 85th percentile. The dashed line is the type median, 14.4; this vessel reported 30.5.
EEOI divides emissions by transport work, which for this vessel and year was 248,949,180 tonne-miles over 56,495 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 45.4% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 1.7% while distance sailed rose 15.0%and CO₂ per nautical mile fell 14.5%.
