ONE INTELLIGENCE against its type

Built in 2023, it is 15 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 235,311 gross tonnage it is larger than 99% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 323 other vessels here, 23 of them container ships. Ocean Network Express is linked to 30 vessels on this register. The returns for 2024–2025 all give MONROVIA as port of registry.

Its 23,480 t of CO₂ for 2025 is 44% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 870.3 kg CO₂, 1.6 times the type median of 545.6 kg. It logged 2,592 hours at sea against a median of 3,155 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025

Position 64 of 1,838 qualifying container ships by EEOI, at the 3rd percentile. The dashed line is the type median, 14.2; this vessel reported 6.0.

0255075100more efficientless efficientThis vessel: 3rd percentile, EEOI 6.0

Across the 30 ranked vessels operated by Ocean Network Express, the median percentile is 11. This vessel is more efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 3,881,061,157 tonne-miles over 26,978 nautical miles.

Reported CO₂ by year

2024: 45,210 t202445,2102025: 23,480 t202523,480

Reported CO₂ in 2025 was 48.1% lower than in 2024, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 48.1% and CO₂ per nautical mile rose 0.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
