NCL SVELGEN against its type

Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,990 gross tonnage it is smaller than 89% 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 180 other vessels here, 110 of them container ships. Its MRV returns name it NCL SVELGEN for 2019–2021 and WEC FRANS HALS for 2022–2025. The reported port of registry changed: Saint John's (2019), then Madeira (2020–2025).

Its 15,550 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 251.4 kg CO₂, 54% below the type median of 545.6 kg. It logged 5,509 hours at sea against a median of 3,155 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2021 (18,304 t) and the lowest 2019 (14,563 t). Its efficiency percentile within the type went from 98 in 2019 to 94 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
