BOW STAR against its type

Built in 2004, it is 6 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,971 gross tonnage it is larger than 88% 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 80 other vessels here, 7 of them chemical tankers. The reported port of registry changed: Singapore (2018–2020), then Bergen (2021–2025).

Its 18,388 t of CO₂ for 2025 is 3.3 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 315.1 kg CO₂, 26% above the type median of 250.2 kg. It logged 4,413 hours at sea against a median of 2,109 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2025 (18,388 t) and the lowest 2021 (5,338 t). Its efficiency percentile within the type went from 20 in 2018 to 56 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 752 of 1,348 qualifying chemical tankers by EEOI, at the 56th percentile. The dashed line is the type median, 14.4; this vessel reported 15.7.

EEOI divides emissions by transport work, which for this vessel and year was 1,168,260,483 tonne-miles over 58,365 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 65.8% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 171.1% while distance sailed rose 206.3%and CO₂ per nautical mile fell 11.5%.That points mainly to how much the vessel sailed, rather than the other.
