TAI HUA WAN against its type
Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 7,414 gross tonnage it is smaller than 97% of the other 2,841 oil tankers with a recorded tonnage. It is one of 30 oil tankers here under the China flag, 0.8% of the 3,548 on the register. The returns for 2023–2025 all give HAI KOU as port of registry.
Its 8,483 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 178.5 kg CO₂, 56% below the type median of 403.2 kg. It logged 4,307 hours at sea against a median of 2,030 hours for its type that year. 17.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.
