KATELINA against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,382 gross tonnage it is smaller than 93% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The same builder is recorded for 3 other vessels here, 2 of them chemical tankers. The reported port of registry changed: Gibraltar (2018–2023), then Madeira (2024–2025).
Its 6,516 t of CO₂ for 2025 is 18% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 181.6 kg CO₂, 27% below the type median of 250.2 kg. It logged 3,555 hours at sea against a median of 2,106 hours for its type that year. 11.5% 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 (8,283 t) and the lowest 2024 (6,038 t). Its efficiency percentile within the type went from 87 in 2018 to 98 in 2025 (lower is more efficient). Of the 6 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 1,318 of 1,348 qualifying chemical tankers by EEOI, at the 98th percentile. The dashed line is the type median, 14.4; this vessel reported 51.8.
EEOI divides emissions by transport work, which for this vessel and year was 125,861,889 tonne-miles over 35,890 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 21.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 7.9% while distance sailed rose 9.0%and CO₂ per nautical mile fell 1.0%.That points mainly to how much the vessel sailed, rather than the other.
