CHALLENGE PRELUDE against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 28,823 gross tonnage it is smaller than 80% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The same builder is recorded for 114 other vessels here, 20 of them oil tankers. The returns for 2020–2022 all give Hong Kong as port of registry.
Its 8,151 t of CO₂ for 2022 is 13% above the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 291.9 kg CO₂, 30% below the type median of 415.9 kg. It logged 2,286 hours at sea against a median of 1,731 hours for its type that year. 8.0% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Of the 4 sister ships listed below with a 2022 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 1,303 of 1,771 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 8.0; this vessel reported 11.1.
EEOI divides emissions by transport work, which for this vessel and year was 733,004,496 tonne-miles over 27,921 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 196.7% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2020 to 2022, emissions rose 196.7% and CO₂ per nautical mile fell 16.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
