NCC YANBU against its type
Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Fleet Management Limited is linked to 40 vessels on this register. Its MRV returns name it NCC YANBU for 2021–2024 and UOG KORTHI for 2025. The returns for 2021–2025 all give MAJURO as port of registry.
Its 12,268 t of CO₂ for 2025 is 2.2 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 401.9 kg CO₂, 1.6 times the type median of 250.2 kg. It logged 2,559 hours at sea against a median of 2,109 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2025 (12,268 t) and the lowest 2022 (6,039 t). Its efficiency percentile within the type went from 7 in 2021 to 47 in 2025 (lower is more efficient). Of the 7 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 637 of 1,348 qualifying chemical tankers by EEOI, at the 47th percentile. The dashed line is the type median, 14.4; this vessel reported 13.9.
Across the 24 ranked vessels operated by Fleet Management Limited, the median percentile is 38. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 880,058,106 tonne-miles over 30,527 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 23.6% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 17.1% and CO₂ per nautical mile fell 0.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
