AYSENAZ against its type
Built in 1993, it is 17 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 5,401 gross tonnage it is smaller than 97% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 29 chemical tankers here under the Türkiye flag, 1.2% of the 2,344 on the register. The returns for 2018–2024 all give Istanbul as port of registry.
Its 4,049 t of CO₂ for 2024 is 31% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 159.9 kg CO₂, 37% below the type median of 253.5 kg. It logged 3,654 hours at sea against a median of 2,177 hours for its type that year. 9.9% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 6 years with reported emissions, the highest was 2024 (4,049 t) and the lowest 2022 (1,491 t). Its efficiency percentile within the type went from 80 in 2018 to 92 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 1,099 of 1,194 qualifying chemical tankers by EEOI, at the 92nd percentile. The dashed line is the type median, 15.9; this vessel reported 41.7.
EEOI divides emissions by transport work, which for this vessel and year was 97,125,930 tonne-miles over 25,325 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 35.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2023 to 2024, emissions rose 115.3% and CO₂ per nautical mile rose 7.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
