BOW TRIBUTE against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,521 gross tonnage it is larger than 96% 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 983 other vessels here, 330 of them chemical tankers. The returns for 2019–2025 all give Bergen as port of registry.
Its 3,490 t of CO₂ for 2025 is 37% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 274.4 kg CO₂, close to the type median of 250.2 kg. It logged 967 hours at sea against a median of 2,109 hours for its type that year. 3.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2022 (7,453 t) and the lowest 2020 (2,107 t). Its efficiency percentile within the type went from 10 in 2019 to 21 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 285 of 1,348 qualifying chemical tankers by EEOI, at the 21st percentile. The dashed line is the type median, 14.4; this vessel reported 9.3.
EEOI divides emissions by transport work, which for this vessel and year was 375,304,301 tonne-miles over 12,722 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 9.8% while distance sailed fell 0.1%and CO₂ per nautical mile fell 9.7%.That points mainly to how efficiently it sailed, rather than the other.
