BOW PIONEER against its type
Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 45,452 gross tonnage it is larger than 100% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 660 other vessels here, one of them a chemical tanker. Its MRV returns name it BOW PIONEER for 2018–2022 and HAFNIA PIONEER for 2023–2025. The returns for 2018–2025 all give Singapore as port of registry.
Its 3,443 t of CO₂ for 2025 is 38% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 404.9 kg CO₂, 1.6 times the type median of 250.2 kg. It logged 799 hours at sea against a median of 2,106 hours for its type that year. 9.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (16,383 t) and the lowest 2024 (983 t). Its efficiency percentile within the type was 3 in both 2019 and 2025. Of the 2 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 36 of 1,348 qualifying chemical tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 14.4; this vessel reported 6.7.
EEOI divides emissions by transport work, which for this vessel and year was 513,952,239 tonne-miles over 8,504 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 100.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 250.2% while distance sailed rose 194.4%and CO₂ per nautical mile rose 18.9%.That points mainly to how much the vessel sailed, rather than the other.
