NYK CONSTELLATION against its type

Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 55,534 gross tonnage it is larger than 58% of the other 3,000 container ships with a recorded tonnage. It is one of 387 container ships here under the Panama flag, 11.1% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. The reported port of registry changed: MAJURO (2019), then PANAMA (2020–2024).

Its 8,971 t of CO₂ for 2025 is 45% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 447.8 kg CO₂, 18% below the type median of 545.6 kg. It logged 1,823 hours at sea against a median of 3,155 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2020 (19,440 t) and the lowest 2022 (2,351 t). Its efficiency percentile within the type went from 51 in 2019 to 94 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
