OOCL CHONGQING against its type
Built in 2013, it is 5 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 141,003 gross tonnage it is larger than 86% 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 2023–2025 all give Hong Kong as port of registry.
Its 30,743 t of CO₂ for 2025 is 1.9 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 916.0 kg CO₂, 1.7 times the type median of 545.6 kg. It logged 2,544 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 3 years with reported emissions, the highest was 2024 (31,207 t) and the lowest 2023 (12,628 t). Its efficiency percentile within the type was 36 in both 2023 and 2025.
