BOW SIRIUS against its type

Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,965 gross tonnage it is larger than 87% 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 80 other vessels here, 7 of them chemical tankers. The returns for 2018–2025 all give Bergen as port of registry.

Its 3,896 t of CO₂ for 2025 is 30% 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 320.5 kg CO₂, 28% above the type median of 250.2 kg. It logged 989 hours at sea against a median of 2,109 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2018 (15,416 t) and the lowest 2023 (3,322 t). Its efficiency percentile within the type went from 32 in 2018 to 19 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 259 of 1,348 qualifying chemical tankers by EEOI, at the 19th percentile. The dashed line is the type median, 14.4; this vessel reported 9.1.

EEOI divides emissions by transport work, which for this vessel and year was 427,613,611 tonne-miles over 12,156 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 74.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions fell 73.3% while distance sailed fell 69.9%and CO₂ per nautical mile fell 11.1%.That points mainly to how much the vessel sailed, rather than the other.
