EASTERN NYMPHAEA 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 8,611 gross tonnage it is smaller than 84% of the other 1,899 chemical tankers with a recorded tonnage. It is the only chemical tanker on this register under the Belize flag. Its MRV returns name it EASTERN NYMPHAEA for 2023–2024 and NGOL OKAVANGO for 2025. The reported port of registry changed: Monrovia (2023–2024), then Belize (2025).
Its 5,258 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 195.4 kg CO₂, 22% below the type median of 250.2 kg. It logged 2,635 hours at sea against a median of 2,109 hours for its type that year. 15.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (5,258 t) and the lowest 2023 (3,076 t). Its efficiency percentile within the type went from 66 in 2023 to 93 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,258 of 1,348 qualifying chemical tankers by EEOI, at the 93rd percentile. The dashed line is the type median, 14.4; this vessel reported 40.7.
EEOI divides emissions by transport work, which for this vessel and year was 129,177,887 tonne-miles over 26,905 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 70.9% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 6.6% and CO₂ per nautical mile rose 12.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
