ALEXANDER against its type

Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,981 gross tonnage it is smaller than 90% of the other 3,000 container ships with a recorded tonnage. It is one of 73 container ships here under the Antigua and Barbuda flag, 2.1% of the 3,495 on the register. Its MRV returns name it JSP SKIRNER for 2018–2023, NCL IKORNNES for 2024 and ALEXANDER for 2025. The returns for 2018–2025 all give St. John's as port of registry.

Its 5,082 t of CO₂ for 2025 is 69% 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 296.9 kg CO₂, 46% below the type median of 545.6 kg. It logged 1,359 hours at sea against a median of 3,155 hours for its type that year. 12.0% 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 (17,643 t) and the lowest 2020 (3,036 t). Its efficiency percentile within the type was 98 in both 2021 and 2024. Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 1.3% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 71.2% and CO₂ per nautical mile rose 7.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 8 MRV reporting years, 4 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
