ALEXIS against its type

Built in 2015, it is 7 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 70,704 gross tonnage it is larger than 62% 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 74 other vessels here, 49 of them container ships. Its MRV returns name it UASC BUBIYAN for 2018, ALEXIS for 2019–2023 and MEXICO EXPRESS for 2024–2025. The returns for 2018–2025 all give MAJURO as port of registry.

Its 35,488 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 440.1 kg CO₂, 19% below the type median of 545.6 kg. It logged 6,088 hours at sea against a median of 3,155 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2021 (55,097 t) and the lowest 2018 (14,587 t). Its efficiency percentile within the type went from 30 in 2018 to 25 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 461 of 1,838 qualifying container ships by EEOI, at the 25th percentile. The dashed line is the type median, 14.2; this vessel reported 9.0.

Reported CO₂ in 2025 was 143.3% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 14.5% while distance sailed rose 68.4%and CO₂ per nautical mile fell 32.0%.That points mainly to how much the vessel sailed, rather than the other.
