BW KALLANG against its type
It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. Its MRV returns name it BW KALLANG for 2021 and HAFNIA KALLANG for 2023–2024. The returns for 2021–2024 all give Singapore as port of registry.
Its 5,998 t of CO₂ for 2024 is 27% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 287.9 kg CO₂, 29% below the type median of 408.2 kg. It logged 1,862 hours at sea against a median of 2,020 hours for its type that year. 7.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 3 years with reported emissions, the highest was 2021 (6,935 t) and the lowest 2023 (3,223 t). Its efficiency percentile within the type went from 52 in 2021 to 37 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 582 of 1,566 qualifying oil tankers by EEOI, at the 37th percentile. The dashed line is the type median, 7.6; this vessel reported 6.6.
EEOI divides emissions by transport work, which for this vessel and year was 906,042,296 tonne-miles over 20,832 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 13.5% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions rose 86.1% while distance sailed rose 70.8%and CO₂ per nautical mile rose 9.0%.That points mainly to how much the vessel sailed, rather than the other.
