ONE INGENUITY 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 136 other vessels here, 5 of them container ships. Ocean Network Express is linked to 30 vessels on this register. The returns for 2023–2025 all give MONROVIA as port of registry.

Its 42,053 t of CO₂ for 2025 is 2.6 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 814.7 kg CO₂, 49% above the type median of 545.6 kg. It logged 4,074 hours at sea against a median of 3,155 hours for its type that year. 3.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2024 (49,188 t) and the lowest 2023 (3,324 t). Its efficiency percentile within the type went from 0 in 2023 to 2 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025

Position 28 of 1,838 qualifying container ships by EEOI, at the 2nd percentile. The dashed line is the type median, 14.2; this vessel reported 5.6.

0255075100more efficientless efficientThis vessel: 2nd percentile, EEOI 5.6

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 7,509,405,357 tonne-miles over 51,619 nautical miles.

Reported CO₂ in 2025 was 1,165.3% higher than in 2023, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 14.5% and CO₂ per nautical mile fell 2.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
