LEO against its type

Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 83,747 gross tonnage it is larger than 81% 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 34 other vessels here, 20 of them oil tankers. The returns for 2018–2022 all give Monrovia as port of registry.

Its 5,974 t of CO₂ for 2022 is 17% below the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 482.3 kg CO₂, 16% above the type median of 415.9 kg. It logged 1,418 hours at sea against a median of 1,731 hours for its type that year. 8.8% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2019 (28,959 t) and the lowest 2022 (5,974 t). Its efficiency percentile within the type went from 20 in 2018 to 43 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ in 2022 was 78.3% lower than in 2018, for EU/EEA voyages only.

From 2021 to 2022, emissions fell 9.8% while distance sailed fell 11.6%and CO₂ per nautical mile rose 2.0%.That points mainly to how much the vessel sailed, rather than the other.
