AMPLEFORTH against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,863 gross tonnage it is larger than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 8 oil tankers here under the Sierra Leone flag, 0.2% of the 3,548 on the register. The same builder is recorded for 194 other vessels here, 56 of them oil tankers. Its MRV returns name it OCEAN QUEST for 2019 and AMPLEFORTH for 2021–2022. The reported port of registry changed: Singapore (2019), then Majuro (2021–2022).
Its 13,265 t of CO₂ for 2022 is 1.8 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 536.3 kg CO₂, 29% above the type median of 415.9 kg. It logged 2,553 hours at sea against a median of 1,731 hours for its type that year. 6.8% 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 (13,265 t) and the lowest 2019 (3,034 t). Its efficiency percentile within the type was 28 in both 2019 and 2022.

Efficiency against its own type2022
Position 502 of 1,771 qualifying oil tankers by EEOI, at the 28th percentile. The dashed line is the type median, 8.0; this vessel reported 6.2.
EEOI divides emissions by transport work, which for this vessel and year was 2,136,035,427 tonne-miles over 24,736 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 337.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2021 to 2022, emissions rose 196.6% while distance sailed rose 189.8%and CO₂ per nautical mile rose 2.3%.That points mainly to how much the vessel sailed, rather than the other.
