BOW SAGA against its type

Built in 2007, it is 3 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 12,806 t of CO₂ for 2025 is 2.3 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 331.1 kg CO₂, 32% above the type median of 250.2 kg. It logged 2,880 hours at sea against a median of 2,109 hours for its type that year. 10.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2021 (15,262 t) and the lowest 2020 (6,351 t). Its efficiency percentile within the type went from 27 in 2018 to 37 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 500 of 1,348 qualifying chemical tankers by EEOI, at the 37th percentile. The dashed line is the type median, 14.4; this vessel reported 12.2.

EEOI divides emissions by transport work, which for this vessel and year was 1,051,415,435 tonne-miles over 38,673 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 26.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions rose 42.5% while distance sailed rose 46.8%and CO₂ per nautical mile fell 2.9%.That points mainly to how much the vessel sailed, rather than the other.
