HERON against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 156,517 gross tonnage it is larger than 88% 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 74 other vessels here, 10 of them oil tankers. The returns for 2018–2022 all give Monrovia as port of registry.
Its 11,360 t of CO₂ for 2021 is 47% above the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 515.0 kg CO₂, 26% above the type median of 409.1 kg. It logged 2,200 hours at sea against a median of 1,921 hours for its type that year. 0.9% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Its efficiency percentile within the type went from 3 in 2019 to 1 in 2021 (lower is more efficient).
No EU/EEA voyages were reported for 2022: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2021
Position 17 of 1,636 qualifying oil tankers by EEOI, at the 1st percentile. The dashed line is the type median, 8.4; this vessel reported 2.8.
EEOI divides emissions by transport work, which for this vessel and year was 4,057,317,857 tonne-miles over 22,059 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 7.9% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2019 to 2021, emissions fell 7.9% while distance sailed rose 19.9%and CO₂ per nautical mile fell 23.2%.
