JULIUS against its type

Built in 2009, it is 1 year newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 15,636 gross tonnage it is smaller than 83% 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 MERCS JAFFNA for 2018–2019, JULIUS for 2020–2022 and MARINA L for 2023–2025. The reported port of registry changed: Colombo (2018–2019), then SAINT-JOHN'S (2023–2025).

Its 11,708 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 253.7 kg CO₂, 54% below the type median of 545.6 kg. It logged 4,498 hours at sea against a median of 3,155 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2021 (22,024 t) and the lowest 2020 (7,496 t). Its efficiency percentile within the type went from 80 in 2018 to 82 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
