ZEUS LUMOS against its type

Built in 2021, it is 13 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 149,525 gross tonnage it is larger than 90% 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 761 other vessels here, 355 of them container ships. Ocean Network Express is linked to 30 vessels on this register. The reported port of registry changed: LONDON (2021–2022), then Monrovia (2023–2025).

Its 35,985 t of CO₂ for 2025 is 2.2 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 695.1 kg CO₂, 27% above the type median of 545.6 kg. It logged 4,320 hours at sea against a median of 3,155 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2022 (38,525 t) and the lowest 2021 (30,542 t). Its efficiency percentile within the type went from 6 in 2021 to 22 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 398 of 1,838 qualifying container ships by EEOI, at the 22nd percentile. The dashed line is the type median, 14.2; this vessel reported 8.5.

0255075100more efficientless efficientThis vessel: 22nd percentile, EEOI 8.5

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

EEOI divides emissions by transport work, which for this vessel and year was 4,233,474,118 tonne-miles over 51,765 nautical miles.

Reported CO₂ in 2025 was 17.8% higher than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 15.6% while distance sailed rose 24.8%and CO₂ per nautical mile fell 7.3%.That points mainly to how much the vessel sailed, rather than the other.
