MAERSK BUTON against its type

Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 35,835 gross tonnage it is smaller than 60% 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 133 other vessels here, 105 of them container ships. The returns for 2018–2023 all give Singapore as port of registry.

Its 17,904 t of CO₂ for 2023 is 22% above the median of 14,627 t among the 1,920 container ships on this register that reported for 2023. Per nautical mile it emitted 407.8 kg CO₂, 20% below the type median of 509.2 kg. It logged 3,009 hours at sea against a median of 2,716 hours for its type that year. 1.4% of its 2023 emissions were at berth; the median for container ships was 4.0%. Across 6 years with reported emissions, the highest was 2020 (34,199 t) and the lowest 2019 (13,619 t). Its efficiency percentile within the type went from 51 in 2018 to 65 in 2023 (lower is more efficient).
