ALEKSEY KOSYGIN against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 87,146 gross tonnage it is larger than 86% 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 660 other vessels here, 159 of them oil tankers. The returns for 2018–2022 all give Monrovia as port of registry.
Its 5,679 t of CO₂ for 2022 is 21% 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 618.8 kg CO₂, 49% above the type median of 415.9 kg. It logged 2,083 hours at sea against a median of 1,731 hours for its type that year. 12.8% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2020 (34,647 t) and the lowest 2022 (5,679 t). Its efficiency percentile within the type went from 30 in 2018 to 85 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.

Efficiency against its own type2022
Position 1,509 of 1,771 qualifying oil tankers by EEOI, at the 85th percentile. The dashed line is the type median, 8.0; this vessel reported 14.8.
EEOI divides emissions by transport work, which for this vessel and year was 383,204,453 tonne-miles over 9,177 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 66.0% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 21.5% and CO₂ per nautical mile fell 81.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
