MAERSK NIENBURG 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 26,836 gross tonnage it is smaller than 68% 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. Its MRV returns name it MAERSK NIENBURG for 2018–2020 and SANTA MARTA EXPRESS for 2021–2025. The reported port of registry changed: Hong Kong (2018–2023), then Monrovia (2024–2025).

Its 24,332 t of CO₂ for 2025 is 49% 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 395.9 kg CO₂, 27% below the type median of 545.6 kg. It logged 4,468 hours at sea against a median of 3,155 hours for its type that year. 2.5% 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 (37,604 t) and the lowest 2020 (3,349 t). Its efficiency percentile within the type went from 61 in 2018 to 77 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
