OCEAN CASTLE 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 18,825 gross tonnage it is smaller than 76% of the other 3,000 container ships with a recorded tonnage. It is one of 336 container ships here under the Malta flag, 9.6% of the 3,495 on the register. The same builder is recorded for 101 other vessels here, 74 of them container ships. The reported port of registry changed: Valetta (2019–2020), then Valletta (2021–2024).
Its 5,027 t of CO₂ for 2024 is 72% below the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 210.8 kg CO₂, 60% below the type median of 528.5 kg. It logged 2,179 hours at sea against a median of 3,325 hours for its type that year. 7.1% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 7 years with reported emissions, the highest was 2022 (7,822 t) and the lowest 2021 (4,514 t). Its efficiency percentile within the type went from 82 in 2018 to 57 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 952 of 1,661 qualifying container ships by EEOI, at the 57th percentile. The dashed line is the type median, 15.4; this vessel reported 17.4.
EEOI divides emissions by transport work, which for this vessel and year was 289,546,659 tonne-miles over 23,843 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 15.6% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 12.0% while distance sailed rose 1.0%and CO₂ per nautical mile fell 12.8%.That points mainly to how efficiently it sailed, rather than the other.
