ORIENTAL VIOLA against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 9,442 gross tonnage it is smaller than 82% 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 same builder is recorded for 17 other vessels here, 14 of them chemical tankers. The returns for 2020–2025 all give Panama as port of registry.
Its 4,839 t of CO₂ for 2025 is 13% 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 148.1 kg CO₂, 41% below the type median of 250.2 kg. It logged 2,841 hours at sea against a median of 2,109 hours for its type that year. 4.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (6,439 t) and the lowest 2023 (3,009 t). Its efficiency percentile within the type went from 49 in 2020 to 62 in 2025 (lower is more efficient). Of the 3 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 833 of 1,348 qualifying chemical tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 14.4; this vessel reported 17.6.
EEOI divides emissions by transport work, which for this vessel and year was 275,232,082 tonne-miles over 32,680 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.9% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 33.2% 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.
