OOCL SEOUL against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 89,097 gross tonnage it is larger than 69% of the other 3,000 container ships with a recorded tonnage. It is one of 202 container ships here under the Hong Kong flag, 5.8% of the 3,495 on the register. The same builder is recorded for 563 other vessels here, 243 of them container ships. The returns for 2021–2025 all give HONG KONG as port of registry.
Its 24,861 t of CO₂ for 2025 is 1.5 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 704.5 kg CO₂, 29% above the type median of 545.6 kg. It logged 2,891 hours at sea against a median of 3,155 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2022 (39,764 t) and the lowest 2025 (24,861 t). Its efficiency percentile within the type went from 34 in 2021 to 43 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 783 of 1,838 qualifying container ships by EEOI, at the 43rd percentile. The dashed line is the type median, 14.2; this vessel reported 12.3.
EEOI divides emissions by transport work, which for this vessel and year was 2,027,812,398 tonne-miles over 35,287 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.2% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 9.0% while distance sailed rose 9.8%and CO₂ per nautical mile fell 17.1%.That points mainly to how efficiently it sailed, rather than the other.
