NOCTURNE 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 22,988 gross tonnage it is smaller than 51% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The returns for 2022–2025 all give MAJURO as port of registry.
Its 2,574 t of CO₂ for 2025 is 53% 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 294.0 kg CO₂, 18% above the type median of 250.2 kg. It logged 763 hours at sea against a median of 2,109 hours for its type that year. 9.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (11,478 t) and the lowest 2023 (2,555 t). Its efficiency percentile within the type went from 14 in 2022 to 73 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 982 of 1,348 qualifying chemical tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 14.4; this vessel reported 21.9.
EEOI divides emissions by transport work, which for this vessel and year was 117,434,763 tonne-miles over 8,756 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 0.7% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 77.6% while distance sailed fell 80.0%and CO₂ per nautical mile rose 12.2%.That points mainly to how much the vessel sailed, rather than the other.
