NIPPON PRINCESS 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 55,909 gross tonnage it is smaller than 57% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 57 other vessels here, 42 of them oil tankers. The returns for 2018–2023 all give Majuro as port of registry.
Its 8,776 t of CO₂ for 2023 is 17% above the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 496.8 kg CO₂, 22% above the type median of 408.5 kg. It logged 1,846 hours at sea against a median of 1,807 hours for its type that year. 10.7% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 4 years with reported emissions, the highest was 2019 (18,643 t) and the lowest 2018 (5,369 t). Its efficiency percentile within the type went from 83 in 2018 to 68 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2023
Position 1,096 of 1,615 qualifying oil tankers by EEOI, at the 68th percentile. The dashed line is the type median, 8.0; this vessel reported 10.1.
EEOI divides emissions by transport work, which for this vessel and year was 870,602,182 tonne-miles over 17,664 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 63.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2020 to 2023, emissions fell 33.9% while distance sailed fell 38.6%and CO₂ per nautical mile rose 7.7%.That points mainly to how much the vessel sailed, rather than the other.
