BW COLUMBIA 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 43,797 gross tonnage it is larger than 99% 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. Its MRV returns name it BW COLUMBIA for 2018–2021, HAFNIA COLUMBIA for 2022 and PM CROWN for 2024. The returns for 2018–2024 all give Singapore as port of registry.
Its 2,990 t of CO₂ for 2022 is 49% below the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 328.4 kg CO₂, 23% above the type median of 266.3 kg. It logged 906 hours at sea against a median of 1,995 hours for its type that year. 5.3% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 4 years with reported emissions, the highest was 2019 (7,043 t) and the lowest 2021 (2,948 t). Its efficiency percentile within the type went from 25 in 2018 to 46 in 2022 (lower is more efficient).
No EU/EEA voyages were reported for 2024: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 811 of 1,771 qualifying oil tankers by EEOI, at the 46th percentile. The dashed line is the type median, 8.0; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 392,967,148 tonne-miles over 9,107 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 44.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2023, so the series has gaps.
From 2021 to 2022, emissions rose 1.4% while distance sailed rose 9.2%and CO₂ per nautical mile fell 7.1%.
