RAMELIA against its type
Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 12,770 gross tonnage it is smaller than 66% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 17 chemical tankers here under the Sweden flag, 0.7% of the 2,344 on the register. The same builder is recorded for 40 other vessels here, 32 of them chemical tankers. The returns for 2019–2025 all give Donsö as port of registry.
Its 7,073 t of CO₂ for 2025 is 28% 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 145.7 kg CO₂, 42% below the type median of 250.2 kg. It logged 4,635 hours at sea against a median of 2,109 hours for its type that year. 12.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2025 (7,073 t) and the lowest 2019 (2,442 t). Its efficiency percentile within the type went from 31 in 2019 to 69 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 928 of 1,348 qualifying chemical tankers by EEOI, at the 69th percentile. The dashed line is the type median, 14.4; this vessel reported 20.3.
EEOI divides emissions by transport work, which for this vessel and year was 348,104,331 tonne-miles over 48,538 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 189.6% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 16.4% while distance sailed rose 25.7%and CO₂ per nautical mile fell 7.4%.That points mainly to how much the vessel sailed, rather than the other.
