DUKE OF PEACE against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,835 gross tonnage it is smaller than 60% of the other 2,841 oil tankers with a recorded tonnage. It is one of 58 oil tankers here under the Norway flag, 1.6% of the 3,548 on the register. The same builder is recorded for 56 other vessels here, 24 of them oil tankers. Its MRV returns name it MARILEE for 2018–2020 and DUKE OF PEACE for 2022–2023. The reported port of registry changed: Larvik (2018–2020), then Monrovia (2022–2023).
Its 4,011 t of CO₂ for 2023 is 46% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 397.2 kg CO₂, close to the type median of 408.5 kg. It logged 823 hours at sea against a median of 1,807 hours for its type that year. 4.3% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 5 years with reported emissions, the highest was 2018 (13,482 t) and the lowest 2022 (3,591 t). Its efficiency percentile within the type went from 64 in 2018 to 44 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 704 of 1,615 qualifying oil tankers by EEOI, at the 44th percentile. The dashed line is the type median, 8.0; this vessel reported 7.3.
EEOI divides emissions by transport work, which for this vessel and year was 547,923,497 tonne-miles over 10,098 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 70.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2022 to 2023, emissions rose 11.7% while distance sailed rose 13.6%and CO₂ per nautical mile fell 1.7%.That points mainly to how much the vessel sailed, rather than the other.
