ARIONAS against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,270 gross tonnage it is larger than 51% 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 same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it ARIONAS for 2018–2020 and HACI KEMAL KA for 2021–2025. The returns for 2021–2025 all give İSTANBUL as port of registry.
Its 2,913 t of CO₂ for 2025 is 47% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 289.1 kg CO₂, 16% above the type median of 250.2 kg. It logged 918 hours at sea against a median of 2,106 hours for its type that year. 13.1% 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 (11,179 t) and the lowest 2022 (420 t). Its efficiency percentile within the type went from 53 in 2018 to 64 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 863 of 1,348 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 14.4; this vessel reported 18.2.
EEOI divides emissions by transport work, which for this vessel and year was 159,723,136 tonne-miles over 10,077 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 73.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 105.9% while distance sailed rose 122.4%and CO₂ per nautical mile fell 7.4%.That points mainly to how much the vessel sailed, rather than the other.
