MAERSK HALIFAX against its type
Built in 2017, it is 9 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 153,744 gross tonnage it is larger than 93% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% 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 HONAM for 2018 and MAERSK HALIFAX for 2019–2025. The returns for 2018–2025 all give Singapore as port of registry.
Its 18,954 t of CO₂ for 2025 is 16% 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 799.8 kg CO₂, 47% above the type median of 545.6 kg. It logged 1,452 hours at sea against a median of 3,155 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2024 (23,882 t) and the lowest 2018 (1,966 t). Its efficiency percentile within the type went from 21 in 2018 to 9 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
