ARGENT BLOOM against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 19,440 gross tonnage it is smaller than 57% 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. Its MRV returns name it ARGENT BLOOM for 2018–2020 and BOW CAROLINE for 2021–2025. The reported port of registry changed: PANAMA (2018–2020), then Bergen (2021–2025).
Its 7,879 t of CO₂ for 2025 is 42% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 278.2 kg CO₂, 11% above the type median of 250.2 kg. It logged 2,446 hours at sea against a median of 2,106 hours for its type that year. 8.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2024 (10,264 t) and the lowest 2020 (1,392 t). Its efficiency percentile within the type went from 69 in 2018 to 44 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 589 of 1,348 qualifying chemical tankers by EEOI, at the 44th percentile. The dashed line is the type median, 14.4; this vessel reported 13.3.
EEOI divides emissions by transport work, which for this vessel and year was 593,288,404 tonne-miles over 28,324 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 93.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions fell 23.2% while distance sailed fell 34.6%and CO₂ per nautical mile rose 17.3%.That points mainly to how much the vessel sailed, rather than the other.
