MOSKOVSKY PROSPECT against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 62,504 gross tonnage it is larger than 59% of the other 2,841 oil tankers with a recorded tonnage. It is one of 3 oil tankers here under the Oman flag, 0.1% of the 3,548 on the register. The same builder is recorded for 461 other vessels here, 179 of them oil tankers. The returns for 2018–2022 all give Monrovia as port of registry.
Its 5,478 t of CO₂ for 2022 is 24% 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 472.0 kg CO₂, 13% above the type median of 415.9 kg. It logged 1,680 hours at sea against a median of 1,731 hours for its type that year. 23.4% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2018 (28,835 t) and the lowest 2022 (5,478 t). Its efficiency percentile within the type went from 51 in 2018 to 46 in 2022 (lower is more efficient). Of the 3 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 806 of 1,771 qualifying oil tankers by EEOI, at the 46th percentile. The dashed line is the type median, 8.0; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 721,760,211 tonne-miles over 11,606 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 81.0% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 79.6% while distance sailed fell 79.9%and CO₂ per nautical mile rose 1.3%.That points mainly to how much the vessel sailed, rather than the other.
