BOW GEMINI against its type

Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 26,364 gross tonnage it is larger than 62% 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 118 other vessels here, 7 of them chemical tankers. The returns for 2018–2025 all give Bergen as port of registry.

Its 12,053 t of CO₂ for 2025 is 2.2 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 316.5 kg CO₂, 27% above the type median of 250.2 kg. It logged 3,038 hours at sea against a median of 2,109 hours for its type that year. 9.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (13,836 t) and the lowest 2023 (3,994 t). Its efficiency percentile within the type went from 34 in 2018 to 35 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 476 of 1,348 qualifying chemical tankers by EEOI, at the 35th percentile. The dashed line is the type median, 14.4; this vessel reported 11.9.

EEOI divides emissions by transport work, which for this vessel and year was 1,008,621,757 tonne-miles over 38,087 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 12.9% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 39.7% while distance sailed rose 33.0%and CO₂ per nautical mile rose 5.0%.That points mainly to how much the vessel sailed, rather than the other.
