CANGJIE: CO₂ emissions 2018–2023

CANGJIE against its type

Built in 2005, it is 5 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 57,248 gross tonnage it is smaller than 53% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. Its MRV returns name it NS CHALLENGER for 2018–2021 and CANGJIE for 2023. The reported port of registry changed: Monrovia (2018–2021), then AVATIU (2023).

Its 6,227 t of CO₂ for 2023 is 17% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 429.6 kg CO₂, close to the type median of 408.5 kg. It logged 1,395 hours at sea against a median of 1,807 hours for its type that year. 4.3% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 5 years with reported emissions, the highest was 2020 (20,868 t) and the lowest 2023 (6,227 t). Its efficiency percentile within the type went from 69 in 2018 to 40 in 2023 (lower is more efficient).

Efficiency against its own type2023

Position 648 of 1,615 qualifying oil tankers by EEOI, at the 40th percentile. The dashed line is the type median, 8.0; this vessel reported 7.0.

EEOI divides emissions by transport work, which for this vessel and year was 884,461,648 tonne-miles over 14,494 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 5.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2021 to 2023, emissions fell 64.3% while distance sailed fell 57.8%and CO₂ per nautical mile fell 15.2%.That points mainly to how much the vessel sailed, rather than the other.
