BOCHEM OSLO against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 19,910 gross tonnage it is smaller than 56% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The same builder is recorded for 76 other vessels here, 58 of them chemical tankers. The reported port of registry changed: Panama (2018–2020), then MADEIRA (2021–2025).
Its 3,875 t of CO₂ for 2025 is 30% 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 260.8 kg CO₂, close to the type median of 250.2 kg. It logged 1,339 hours at sea against a median of 2,106 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2019 (10,001 t) and the lowest 2018 (3,107 t). Its efficiency percentile within the type went from 33 in 2018 to 63 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 846 of 1,348 qualifying chemical tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 14.4; this vessel reported 17.8.
EEOI divides emissions by transport work, which for this vessel and year was 217,326,977 tonne-miles over 14,860 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 19.4% while distance sailed rose 26.3%and CO₂ per nautical mile fell 5.4%.That points mainly to how much the vessel sailed, rather than the other.
