ELBSUN against its type
Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,983 gross tonnage it is smaller than 90% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 44 other vessels here, 23 of them container ships. Its MRV returns name it EXPANSA for 2018–2020 and ELBSUN for 2021–2025. The reported port of registry changed: Saint John's (2018–2019), then Madeira (2020–2025).
Its 11,844 t of CO₂ for 2025 is 28% 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 271.7 kg CO₂, 50% below the type median of 545.6 kg. It logged 3,797 hours at sea against a median of 3,155 hours for its type that year. 15.2% 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 (17,322 t) and the lowest 2022 (10,315 t). Its efficiency percentile within the type went from 91 in 2018 to 95 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.
