STAR OSPREY against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,068 gross tonnage it is larger than 92% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The returns for 2019–2025 all give Panama as port of registry.
Its 3,899 t of CO₂ for 2025 is 30% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 343.3 kg CO₂, 37% above the type median of 250.2 kg. It logged 1,060 hours at sea against a median of 2,109 hours for its type that year. 14.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (14,817 t) and the lowest 2024 (362 t). Its efficiency percentile within the type went from 20 in 2019 to 46 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 620 of 1,348 qualifying chemical tankers by EEOI, at the 46th percentile. The dashed line is the type median, 14.4; this vessel reported 13.8.
EEOI divides emissions by transport work, which for this vessel and year was 283,555,636 tonne-miles over 11,356 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 3.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 976.6% and CO₂ per nautical mile fell 17.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
