BOW EXPLORER against its type

Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,627 gross tonnage it is larger than 78% 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 8,938 t of CO₂ for 2025 is 1.6 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 345.6 kg CO₂, 38% above the type median of 250.2 kg. It logged 1,886 hours at sea against a median of 2,109 hours for its type that year. 9.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2024 (12,970 t) and the lowest 2020 (2,940 t). Its efficiency percentile within the type went from 47 in 2020 to 62 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 836 of 1,348 qualifying chemical tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 14.4; this vessel reported 17.6.

EEOI divides emissions by transport work, which for this vessel and year was 507,271,850 tonne-miles over 25,863 nautical miles.

Reported CO₂ in 2025 was 204.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions fell 31.1% while distance sailed fell 37.8%and CO₂ per nautical mile rose 10.8%.That points mainly to how much the vessel sailed, rather than the other.
