SILVERSTONE against its type

Built in 2020, it is 10 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 154,046 gross tonnage it is larger than 87% 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 461 other vessels here, 179 of them oil tankers. The returns for 2020–2025 all give MONROVIA as port of registry.

Its 5,339 t of CO₂ for 2022 is 26% 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 626.4 kg CO₂, 1.5 times the type median of 415.9 kg. It logged 664 hours at sea against a median of 1,731 hours for its type that year. 18.8% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 3 years with reported emissions, the highest was 2022 (5,339 t) and the lowest 2021 (2,894 t). Its efficiency percentile within the type went from 13 in 2020 to 26 in 2022 (lower is more efficient). Of the 2 sister ships listed below with a 2022 return, 2 reported a lower CO₂ per nautical mile than this vessel.

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022

Position 458 of 1,771 qualifying oil tankers by EEOI, at the 26th percentile. The dashed line is the type median, 8.0; this vessel reported 6.0.

EEOI divides emissions by transport work, which for this vessel and year was 888,404,326 tonne-miles over 8,524 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 1.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2021 to 2022, emissions rose 84.5% while distance sailed rose 107.3%and CO₂ per nautical mile fell 11.0%.That points mainly to how much the vessel sailed, rather than the other.
