SILVER 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 60,379 gross tonnage it is larger than 53% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 360 other vessels here, 27 of them oil tankers. Its MRV returns name it ZARIFA ALIYEVA for 2018–2020 and SILVER for 2021–2022. The returns for 2018–2022 all give Valetta as port of registry.
Its 15,370 t of CO₂ for 2022 is 2.1 times the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 466.0 kg CO₂, 12% above the type median of 415.9 kg. It logged 3,006 hours at sea against a median of 1,731 hours for its type that year. 16.6% 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 (22,062 t) and the lowest 2019 (13,425 t). Its efficiency percentile within the type went from 51 in 2018 to 69 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 1,226 of 1,771 qualifying oil tankers by EEOI, at the 69th percentile. The dashed line is the type median, 8.0; this vessel reported 10.3.
EEOI divides emissions by transport work, which for this vessel and year was 1,486,441,006 tonne-miles over 32,984 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 30.3% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 25.6% while distance sailed fell 34.3%and CO₂ per nautical mile rose 13.3%.That points mainly to how much the vessel sailed, rather than the other.
