BOW ORION against its type

Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,000 gross tonnage it is larger than 67% 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. The same builder is recorded for 204 other vessels here, 11 of them chemical tankers. The returns for 2020–2025 all give Bergen as port of registry.

Its 6,226 t of CO₂ for 2025 is 13% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 368.1 kg CO₂, 47% above the type median of 250.2 kg. It logged 1,381 hours at sea against a median of 2,109 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2021 (8,354 t) and the lowest 2025 (6,226 t). Its efficiency percentile within the type went from 15 in 2020 to 21 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 283 of 1,348 qualifying chemical tankers by EEOI, at the 21st percentile. The dashed line is the type median, 14.4; this vessel reported 9.3.

2020: 7,990 t20207,9902021: 8,354 t20212025: 6,226 t20256,226

Reported CO₂ in 2025 was 22.1% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.

From 2021 to 2025, emissions fell 25.5% while distance sailed fell 36.5%and CO₂ per nautical mile rose 17.4%.That points mainly to how much the vessel sailed, rather than the other.
