AS NINA against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 36,087 gross tonnage it is smaller than 59% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Marshall Islands flag, 3.4% of the 3,495 on the register. The same builder is recorded for 16 other vessels here, 14 of them container ships. Its MRV returns name it RIO CENTAURUS for 2019 and AS NINA for 2023–2025. The returns for 2019–2025 all give Majuro as port of registry.
Its 29,782 t of CO₂ for 2025 is 1.8 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 434.4 kg CO₂, 20% below the type median of 545.6 kg. It logged 5,534 hours at sea against a median of 3,155 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2025 (29,782 t) and the lowest 2019 (4,503 t). Its efficiency percentile within the type went from 61 in 2023 to 70 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 1,294 of 1,838 qualifying container ships by EEOI, at the 70th percentile. The dashed line is the type median, 14.2; this vessel reported 20.8.
EEOI divides emissions by transport work, which for this vessel and year was 1,433,185,756 tonne-miles over 68,564 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 561.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 51.4% while distance sailed rose 86.8%and CO₂ per nautical mile fell 18.9%.That points mainly to how much the vessel sailed, rather than the other.
