OVIT against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,444 gross tonnage it is smaller than 93% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. Its MRV returns name it THERASIA M for 2019–2024 and OVIT for 2025. The reported port of registry changed: Catania (2019–2024), then Valletta (2025).
Its 6,708 t of CO₂ for 2025 is 21% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 269.3 kg CO₂, close to the type median of 250.2 kg. It logged 4,171 hours at sea against a median of 2,109 hours for its type that year. 11.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2020 (11,686 t) and the lowest 2019 (6,286 t). Its efficiency percentile within the type went from 99 in 2019 to 100 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,347 of 1,348 qualifying chemical tankers by EEOI, at the 100th percentile. The dashed line is the type median, 14.4; this vessel reported 85.3.
EEOI divides emissions by transport work, which for this vessel and year was 78,664,478 tonne-miles over 24,912 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 6.7% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 22.0% while distance sailed fell 23.8%and CO₂ per nautical mile rose 2.4%.That points mainly to how much the vessel sailed, rather than the other.
