BOW OLYMPUS against its type
Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,000 gross tonnage it is larger than 67% 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 204 other vessels here, 11 of them chemical tankers. The returns for 2020–2025 all give Bergen as port of registry.
Its 11,882 t of CO₂ for 2025 is 2.1 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 312.2 kg CO₂, 25% above the type median of 250.2 kg. It logged 2,934 hours at sea against a median of 2,106 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2025 (11,882 t) and the lowest 2020 (3,407 t). Its efficiency percentile within the type went from 15 in 2020 to 38 in 2025 (lower is more efficient). Of the 4 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 516 of 1,348 qualifying chemical tankers by EEOI, at the 38th percentile. The dashed line is the type median, 14.4; this vessel reported 12.3.
EEOI divides emissions by transport work, which for this vessel and year was 964,444,805 tonne-miles over 38,062 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 248.8% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 61.2% while distance sailed rose 73.4%and CO₂ per nautical mile fell 7.1%.That points mainly to how much the vessel sailed, rather than the other.
