NYK ROMULUS 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 55,487 gross tonnage it is larger than 57% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 461 other vessels here, 155 of them container ships. The returns for 2018–2025 all give SINGAPORE as port of registry.

Its 11,936 t of CO₂ for 2025 is 27% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 532.5 kg CO₂, close to the type median of 545.6 kg. It logged 1,674 hours at sea against a median of 3,155 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (26,833 t) and the lowest 2024 (8,726 t). Its efficiency percentile within the type went from 54 in 2018 to 60 in 2025 (lower is more efficient). Of the 4 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 1,107 of 1,838 qualifying container ships by EEOI, at the 60th percentile. The dashed line is the type median, 14.2; this vessel reported 17.1.

EEOI divides emissions by transport work, which for this vessel and year was 699,654,162 tonne-miles over 22,416 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 55.5% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 36.8% and CO₂ per nautical mile fell 3.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
